This guide is for the moment of deciding which provider to buy from. It doesn't make the choice for you; instead, it lays out the dimensions to judge: line types, bandwidth and concurrency, billing models, device count and sharing, refunds and support, and how to spot common pitfalls. All prices and guarantee terms come from the pricing page fact sheet, so you can compare with confidence.

01Three things to think through before you buy

The answer to choosing a cross-border network service almost always comes down to your use case. The same service can feel fast to one person and sluggish to another; most of the time it's not the service quality fluctuating, but a mismatch between the use case and the line's characteristics. Before you start comparing, write down three things: your main use, how many devices and people will use it at the same time, and your rough monthly data habits.

1.1 Your main use determines how sensitive you are to stability

Uses fall into roughly four categories. The first is everyday browsing and search: visiting international sites, looking up information, reading news - light traffic, high tolerance for fluctuation, and any line type can handle it. The second is AI tools such as ChatGPT, Claude, and Gemini, which feature long sessions and frequent requests; when a connection drops you have to start over, so they're sensitive to stability and packet loss. The third is streaming: Netflix, YouTube, Disney+, and HBO demand high bandwidth - an hour of 4K streaming uses several GB - and are sensitive to buffering. The fourth is remote work: accessing overseas systems, Git repositories, and cloud consoles, where both disconnects and latency are a problem.

Write down your main use, and you'll have a basis for choosing line types and billing tiers later: if AI tools are primary, prioritize line stability and evening peak performance; if streaming is primary, focus on bandwidth and data allowance; if browsing is primary, the basic tier is usually enough.

1.2 People and devices determine your account strategy

The number of devices used simultaneously is the second variable to pin down. One person using a phone plus a computer, versus a family of several people each using multiple devices, makes very different demands on account strategy. Two restriction models are common: limiting by logged-in device count, where the oldest device gets kicked out when you exceed the limit; and limiting by simultaneous connections, where new devices can't connect once you're over. Both mean that "bought N devices" doesn't equal "N devices usable at any time".

If several people in the household share the service, or you have multiple devices online at once, a service with no device limit is more convenient. VPNYS subscriptions have no device limit: Windows, macOS, iOS, Android, and Linux clients can all be installed, there's no device cap at the account level, and family members can use it independently. This is covered in more detail in Chapter 5.

1.3 Budget and data habits determine your billing tier

The third thing is data habits. Light users get by with a few dozen GB a month; heavy streaming users can burn through several hundred GB. Data habits map directly to billing tiers: monthly plans come in three tiers - ¥9.9/month with 60GB, ¥18/month with 250GB, ¥28/month with 500GB - with data resetting each month on the activation date; if your usage fluctuates, data packs (¥158/300GB, ¥358/1000GB, ¥658/3000GB) last until used up and never expire, which suits "some months are heavy" scenarios. See Chapter 4 for a detailed comparison of billing models.

1.4 How this page and the tutorial page divide the work

Before going deeper, let's clarify this page's role. The getting started guide on this site is the quick-start path: sign-up, purchase, retrieving your subscription, importing into a client - the shortest route to using the service. This page is a systematic reference that answers "why choose this way": how line types are divided, how to read bandwidth, how to pick a billing plan, how to avoid pitfalls. If you want to get the flow working first, go to the getting started guide; if you want to understand the reasoning, keep reading.

02How to read line types: IEPL dedicated lines, relay, and direct

Line type is the parameter that affects experience the most in a cross-border network service, and the one most often overlooked. Many users only look at "node count" and "price", but what really determines stability during evening peaks is which kind of link the traffic takes from your location to the destination region. The three mainstream types - IEPL dedicated lines, relay, and direct - differ clearly in cost and experience.

2.1 Definitions of the three line types

An IEPL dedicated line (International Ethernet Private Line) is a carrier-grade point-to-point enterprise line. It doesn't traverse the public internet; instead, a dedicated link is established between the local entry point and the destination region's exit, with bandwidth and routing guaranteed by the carrier and not shared with other traffic. The trade-off is high cost, so providers offering IEPL lines usually position them as a premium option.

A relay line forwards traffic through a third-party relay node. Traffic goes to the relay node first, then onward to the destination region. The relay node's quality determines the whole link's performance: a good relay optimizes routing and avoids congestion, while a poor one adds an extra hop of latency. Cost sits between dedicated lines and direct connections.

A direct line is the simplest approach: your location connects straight to the destination region's exit node, with the shortest path. Off-peak, direct lines often show good latency; but international exit bandwidth is generally tight during evening peaks, so direct lines tend to fluctuate with it.

2.2 Cost and experience differences

Looking at the three side by side makes the differences clearer. The core value of an IEPL dedicated line is certainty: it isn't shared with other traffic, so bandwidth and latency stay largely stable during evening peaks, suiting scenarios with high stability requirements. The core value of relay is value for money: routing is optimized, performance is good most of the time, and cost is moderate. The core value of direct is low latency: the path is short and off-peak latency is good, suiting uses that are latency-sensitive and tolerant of peak-hour fluctuation.

The recommendation boils down to three sentences: if you use it heavily during evening peaks and care about stability, prioritize lines with IEPL; if you mainly use it during the day and watch your budget, relay offers the best value; if you want low latency and can accept peak-hour fluctuation, direct is worth a try.

2.3 Line type comparison

IEPL Dedicated LineCarrier point-to-point lineHighStable, guaranteed bandwidthLong AI sessions, streaming, remote work
RelayForwarded via relay nodeMediumDepends on relay qualityEveryday browsing, mixed use
DirectDirect to destination regionLowMay fluctuate with exit bandwidthLatency-sensitive, off-peak use

2.4 How to check line types on VPNYS

VPNYS's network covers 110+ countries and 190+ lines; the nodes page lists each line's type and support status by region, so you can check before choosing. If your main use is AI tools or streaming, prioritize lines marked as IEPL dedicated lines; for everyday browsing, relay and direct are usually enough. Line type isn't a "more expensive is better" ranking - it's a trade-off matched to your use case.

03Bandwidth and concurrency: how to judge evening peak smoothness

"No lag during evening peaks" is the most commonly cited selling point for cross-border network services, and the hardest claim to verify. Judging a service's peak-hour performance requires understanding three concepts - bandwidth, concurrency, and overselling - and how they jointly affect the real experience.

3.1 The two meanings of bandwidth numbers

A line's nominal bandwidth and its actual available bandwidth are two different things. Nominal bandwidth is the capacity the provider purchased or leased; actual available bandwidth depends on how many users are on that line at the same time. On shared-bandwidth lines, more users during peak hours means less bandwidth per person; dedicated bandwidth (such as IEPL lines) doesn't drop noticeably as users increase.

So when you see marketing like "1000M bandwidth", ask one follow-up question: is it dedicated to a single user, or shared across the whole line? The latter's actual evening peak experience can fall far below the nominal figure.

3.2 Concurrent connections: how many devices at once

Concurrent connections describe how many devices or connections are using a line at the same moment. No device limit at the account level doesn't mean no physical limit at the line level - a single line's bandwidth and concurrency capacity objectively exist. For ordinary users, the more practical question is: when several devices at home are online at once, do they crowd each other's speed?

When the account has no device cap, devices online at the same time share the bandwidth of the same line; the more devices, the less each gets. That's physics. What you really need to confirm when buying is whether the account level has a cap, and whether the line itself has enough bandwidth headroom.

3.3 The real causes of evening peak slowdowns

Evening peak slowdowns (usually 8-11 pm local time) have three main causes. First, international exit bandwidth congestion - a physical, objective phenomenon: all cross-border traffic passes through international exits, and when exit bandwidth tightens during peak hours, both latency and packet loss rise. Second, overselling of shared bandwidth: the provider sells more bandwidth than it actually purchased, so peak hours inevitably cause contention. Third, overloaded relay nodes: when a relay line's node carries too many users, forwarding efficiency drops noticeably.

Of the three, exit congestion is an industry-wide issue that no provider can fully avoid; overselling and node overload, however, are things a provider can and should control.

3.4 Self-checks for judging line quality

To judge a line's real performance, do three things. First, test at different times: measure speed once off-peak and once during the evening peak, and compare - the smaller the gap, the more headroom the line has. Second, observe continuity: keep using it for a while after connecting and watch for periodic drops or stutters, rather than only the instant speed right after connecting. Third, check the line type: for the same region, lines marked as IEPL dedicated lines usually outperform relay and direct during evening peaks.

The line status component on the VPNYS homepage shows real-time latency and bandwidth for each line, which can serve as a reference when choosing. The data refreshes with the session and reflects line quality at that moment; it is not a long-term commitment.

04Billing models: monthly plans vs. data packs

Cross-border network services mainly use two billing models: monthly subscriptions and data packs. The former charges monthly and resets data monthly, suiting users with steady usage; the latter buys data in one go and lasts until used up, suiting users with fluctuating usage. There's only one basis for choosing: your data habits.

4.1 How to choose among the three monthly tiers

VPNYS monthly subscriptions come in three tiers: ¥9.9/month with 60GB, ¥18/month with 250GB, and ¥28/month with 500GB. Data resets monthly on the activation date, and the allowance is restored automatically in the next cycle.

The 60GB tier suits light users: browsing international sites daily, occasionally using AI tools for research, watching a little video - 60GB a month is usually more than enough. The 250GB tier suits moderate users: frequent AI tool use, a few streaming titles a week - 250GB is a comfortable middle ground. The 500GB tier suits heavy users: streaming every day, frequent large downloads, or a household with several people sharing - 500GB is the worry-free choice.

4.2 Who data packs suit

A data pack is a one-time purchase of data allowance: ¥158/300GB, ¥358/1000GB, ¥658/3000GB, lasting until used up and never expiring. The key difference from monthly subscriptions is that it doesn't expire - buy it, set it aside, and use it whenever you like, with no worry about unused data being zeroed out at month's end.

Data packs suit two kinds of people. One is users with highly variable usage: light most of the time, then a sudden surge during business trips or holidays - buy a pack and keep it ready, activating it whenever needed, which is more flexible than upgrading a monthly plan on the spot. The other is "stockpilers": when the price is right, buy a large allowance and use it slowly over the long term, unconstrained by monthly resets.

4.3 Data reset and mid-cycle upgrade rules

Two rules are worth noting. First, monthly subscription data resets on the activation date each month: for example, if you activate on August 15, your allowance refreshes on the 15th of every month, not on the calendar month. Second, when upgrading mid-cycle, the price difference is prorated to the remaining days - you pay the difference by the day, so upgrading doesn't waste what you've already paid. Both rules are fully explained on the pricing page; before buying, you can check against your own activation date.

4.4 Tier quick reference

TierPriceData RulesBest For
Monthly 60GB¥9.9/month60GB/month, resets on activation dateLight browsing, occasional AI

Data Pack 1000GB¥358Lasts until used up, never expiresLong-term stockpiling
Data Pack 3000GB¥658Lasts until used up, never expiresHeavy long-term use

A simple decision path: estimate your monthly data first - steady usage means a monthly subscription, fluctuating usage means a data pack; if you're unsure among monthly tiers, pick the middle one, since mid-cycle upgrade differences are prorated to remaining days and you won't lose out. Payment methods include Alipay, WeChat Pay, and USDT; after ordering, your subscription is available in the user panel.

05Family sharing and device count: what "no device limit" means

Device limits are among the most confusing terms in cross-border network services. "Supports N devices" sounds clear, but the actual algorithms vary widely: some count logged-in devices, some count simultaneous connections, some count "devices that logged in over the last 30 days". Different algorithms, very different real-world usability.

5.1 Common device limit algorithms

The most common is limiting by logged-in device count. Say the limit is N; when the next device logs in, it's either rejected or the earliest-logged-in device is kicked out. The catch with this algorithm: switching phones, reinstalling the OS, or clearing browser data all consume "device slots", and once they're used up you have to contact support to reset them - a hassle.

Another is limiting by simultaneous connections. Say N devices can be online at once; the next device fails to connect. This algorithm is friendly to users with multiple devices who don't use them at the same time, but unfriendly to households where everyone is online simultaneously.

A third approach sets no device cap at the account level and only limits a single line's concurrency. This is the most hassle-free option, and the one VPNYS uses: no device limit, with Windows, macOS, iOS, Android, and Linux clients all installable, and family members using it independently without affecting each other.

5.2 Account security with family sharing

With no device limit, family sharing becomes easy, which makes account security more important. The subscription link (subscription URL) is the credential for your account - anyone with the link can import and use the service. When sharing with family, only give the subscription link to trusted members; don't post it in group chats or forums, and don't share screenshots of it.

Another practice is importing the subscription independently on each device: VPNYS clients support importing the same subscription on multiple devices at once, with each device connecting independently without interference - no need to prepare different config files for different devices.

06Refunds and support: what guarantees should you expect

Buying a cross-border network service is essentially buying a commitment to network quality for a period of time. Since it's a commitment, there should be a safety net: if you pay and find it unsuitable, can you get a refund? If something goes wrong, can you reach someone? These two things determine how high the cost of trial and error is.

6.1 14-day no-questions-asked refund

Refund protection is one of the terms you should confirm before buying. VPNYS offers a 14-day no-questions-asked refund: within 14 days of your first payment, if you're not satisfied, you can apply for a full refund with no reason required. This means the first two weeks of use carry almost no risk - unsuitable lines, unsatisfactory speeds, or clients you can't get used to can all be refunded.

When comparing services, treat the refund window as a hard criterion: rule out any service with no refund commitment; if the window is very short, consider whether the provider lacks confidence in its own lines. 14 days is a comfortable trial window, enough to cover the whole flow from sign-up and purchase through importing the client to real use.

6.2 Support channels and response expectations

For support, the user panel has a built-in ticket system (#/tickets); after you submit an issue, support staff handle it. When filing a ticket, include three pieces of information: the symptom (can't connect / slow speed / frequent disconnects), the line and client you're using, and when the problem occurs (whether it concentrates during evening peaks). Complete information makes resolution much faster.

Besides tickets, the support page on this site organizes answers to common questions by category; many connection issues can be resolved there without waiting for support to reply.

6.3 Payment methods and delivery

Payment methods include Alipay, WeChat Pay, and USDT. Alipay and WeChat are the most familiar options for users in mainland China, while USDT suits those accustomed to cross-border payments. Once payment is complete, subscription details appear in the user panel immediately - no need to wait for manual activation.

6.4 When not to rely on refunds

A refund is a safety net, not a plan. If you only need the service for a few days, rather than buying and refunding, work out your needs first: light usage means a low monthly tier, fluctuating usage means a data pack. Also, refunds require submitting a request and waiting for processing - treating "refund" as the default plan is less convenient than picking the right tier from the start.

07Spotting common pitfalls: overselling, fly-by-night operators, inflated node counts

The cross-border network service industry has a low barrier to entry, and provider quality varies widely. Most problems aren't "bad service" but "marketing that doesn't match reality". This chapter covers the three most common pitfalls - overselling, inflated node counts, and fly-by-night operators - and how to spot each. The tone is objective, aimed at no competitor in particular, and only sets out criteria for judgment.

7.1 Overselling: the invisible ceiling of shared bandwidth

Overselling is the most common phenomenon in shared-bandwidth models: a provider sells one line's bandwidth to far more users than its capacity, betting that "not everyone will max it out at the same time". It's fine most of the time, but shows during evening peaks - speed plummets, latency spikes, and connections drop frequently.

Three ways to spot it. First, check the line type: lines labeled IEPL are point-to-point and dedicated, leaving little room for overselling; for lines labeled "shared bandwidth", ask about the sharing ratio. Second, test at different times: measure once at peak and once off-peak; a large gap means the line lacks headroom. Third, see whether the provider discloses its line composition: those willing to spell out each line's type usually have more confidence than those reporting only a "total node count".

7.2 Inflated node counts: good-looking numbers don't mean usable lines

Node count is another metric prone to padding. Common tricks include: splitting different protocol entries for the same region into separate counts, so one region becomes several "nodes"; keeping decommissioned or long-unusable lines on the list to pad the numbers; and mixing "country count" with "node count" to create an illusion of scale.

How to check: go to the nodes page and confirm every line has region, type, and status information; spot-check the actual connectivity of a few lines; and be wary if many lines are marked "under maintenance" or show no status updates for a long time. The VPNYS nodes page lists line details by region with each line's type labeled, covering 110+ countries and 190+ lines, with numbers matching the page one-to-one.

7.3 Signs of a fly-by-night operator: price, domain, and support

A provider disappearing is an extreme case, but the warning signs are general. On price: if a service is priced well below the industry's reasonable range - say, a few yuan a month for "unlimited data, unlimited devices" - ask where the costs are covered. On domain: newly registered domains, no ICP filing, and frequent domain changes are all instability signals. On support: tickets going unanswered for long periods, support going silent, and community forums being shut down suggest the provider may have stopped operating.

Conversely, signs of stability include: long-term steady operation, a clear refund commitment, diverse payment methods (Alipay / WeChat Pay / USDT look more legitimate than a single cryptocurrency), and transparent line composition.

Run through this table and most services that "look off" can be identified before you pay. Many users searching for VPN software are actually looking for a service that reliably accesses international websites - the criteria have nothing to do with keywords, and everything to do with line quality and support terms.

08Sign-up and account security: what "no email required" means

Sign-up is the first step of the buying process, and one many people overlook. It directly affects account security and the overall experience. VPNYS requires only a username and password - no email address. This design has two practical benefits, and also calls for one security habit worth noting.

8.1 Sign-up requirements: username + password

No email address means no email is collected at sign-up, so the whole chain of problems - verification codes that never arrive, spam floods, email being used for password recovery - doesn't exist. The sign-up flow is just two steps: set a username and password, done. For users, one less piece of personal information means a shorter sign-up path and less privacy exposure.

One thing to note: with no email as a recovery credential, the username and password are the account's entire credentials, so be sure to remember them. If you forget your password, recovery relies on the username and security information, so it's a good idea to store the username in a password manager at sign-up rather than using a combination you'll forget.

8.2 Account security practices

Three basic account security practices apply to all online services, and matter especially for cross-border network services. First, use a unique password: don't reuse the same password across sites, because if another site leaks, this one suffers too. Second, make it long: a random password of 12+ characters beats any "birthday + sequential digits" combination. Third, use a password manager: let a tool generate and store passwords, so you only need to remember the master password.

8.3 Safeguarding your subscription link

The subscription link (subscription URL) is the credential for importing into a client, essentially equivalent to your account password. Anyone with the link can use the service without knowing your username or password. So: import the subscription link only in official clients; don't screenshot it, forward it, or post it publicly; and when switching devices, copy the subscription link fresh from the user panel rather than digging an old one out of chat history.

If you suspect the subscription link has leaked, you can reset the subscription in the user panel: the old link stops working immediately and a new one is generated. This is a more direct fix than changing your password.

8.4 Privacy boundaries and further reading

The privacy policy (privacy.html) fully explains data handling. For users, a simple principle applies: anything that can be done in the client doesn't require handing account information to a third party; outside official clients, never enter your subscription details on any "accelerator sharing site". When using the service on public Wi-Fi, just connect through the official client - it handles encrypted transport; don't manually configure a proxy on untrusted networks to "save data".

For more detailed security basics, see VPN Safety Basics for Beginners in the blog. The sign-up entry is in the user panel; no email is needed at any point, and the account is active as soon as you submit.

09FAQ quick reference

The questions most often asked when buying are gathered here; all answers come from the pricing page and fact sheet, so you can compare directly.

Is the ¥9.9/month 60GB plan enough?

60GB suits light use: everyday browsing, occasional AI tools, a little video. If you stream daily or use AI tools frequently, consider the ¥18/250GB or ¥28/500GB tier.

Do data packs expire?

No. Data packs last until used up and never expire. The three tiers - ¥158/300GB, ¥358/1000GB, ¥658/3000GB - remain valid indefinitely after purchase.

How does monthly subscription data reset?

It resets monthly on your activation date. For example, if you activate on August 15, your allowance refreshes on the 15th of each month. When upgrading mid-cycle, the price difference is prorated to the remaining days, so you don't waste what you've paid.

What does "no device limit" mean?

There's no device cap at the account level. Windows, macOS, iOS, Android, and Linux clients can all be installed, and family members can use them independently without affecting each other.

How do I get a refund?

14-day no-questions-asked refund. Within 14 days of your first payment, you can apply for a full refund with no reason required, by submitting a request in the user panel.

Do I need an email to sign up?

No. A username and password are all you need - no email address required.
