Is an Annual Plan Worth It? Do Three Calculations First

Long-term plans usually sell themselves on a lower effective monthly price. But that discount only materialises when two things are true at once: you really will use the whole term, and the service stays available throughout it. Treat an annual plan as an expense rather than a saving, and there are at least three calculations to run.

  1. Unit price. Start by estimating how many times a week you'll use it over the next twelve months. Below two or three times a week, the effective monthly price is likely to come out higher than a monthly plan, because idle months still burn money you've already paid.
  2. Usage. Will your needs change? Your work location, the tools you rely on and the number of devices online at once can all shift within a year. The main migration cost of a subscription is reconfiguring clients, but the time spent re-comparing and re-paying counts too.
  3. Exit cost. The one most people skip. Whether the terms state a refund window in days, when that window starts, and which channel the refund goes through all determine what you actually lose when you leave.

Put the three together and you get one line: real cost = amount paid − whatever you can get back for the unused term. The discount only moves the left side; the terms decide the right side.

Payment structureMoney tied upMain riskBest-fit usage pattern
Monthly subscriptionOne monthPicking a tier for peak usage can leave data unusedSteady usage, no long-term commitment
Data packOne-timeAlmost no time risk — use it until it runs outIrregular usage, occasional heavy bursts
Long-term subscriptionOne year or longerThe service shuts down, or you don't use the full termUsage and needs are both predictable

Bottom line: an annual plan isn't off the table — it just shouldn't be bought on the discount alone. Fill in the “what if I don't use the full term, or the service shuts down” cell first, then decide how long a term to take.

How Long Will a Provider Last? Six Signals You Can Check Yourself

Nobody can predict how long a company will stay in business, but there are more signals available before you buy than you'd think. The six below need no insider knowledge and you can verify them yourself; anything you can't verify is itself information.

  • ✅ Refund terms name a specific number of days and a starting point — “60-day no-questions-asked refund”, say — rather than an open-ended “refunds available”.
  • ✅ Data packs state plainly that they're “use until it runs out, never expires”. The balance doesn't depend on continued renewals, and if the provider changes its plans, what you already bought still stands.
  • ✅ More than one payment channel, e.g. Alipay, WeChat Pay and USDT. A range of payment methods says something about how the provider plans to stay around.
  • ✅ The client has a continuous update history and keeps pace with version changes in mainstream protocols such as Shadowsocks, VMess, Trojan, VLESS, Hysteria2 and TUIC.
  • ✅ Subscription links can be reset self-service, with no ticket and no waiting. A dead link is the most common one-off failure in long-term use.
  • ✅ Tickets or live chat have a stated response time, rather than just an email address.

Conversely, be cautious with wording like this: “refunds supported” with no number of days; data packs with an expiry date; only one payment channel; a client changelog that stopped two years ago. None of it is illegal, but it leaves the risk with the person paying.

Run the six checks and what you get is a risk list, not a verdict of good or bad. Which provider suits you depends on which item you care about most.

Refund terms: From Promise to Enforceable

Refund terms are the most valuable page in a long-term subscription, and the easiest to gloss over in one sentence. To judge whether they can actually be enforced, look at four elements: days, start date, refund channel and exceptions.

  • Days. “60-day no-questions-asked refund” and “refunds available” are two different things — with the first, you can count the days yourself.
  • Start date. Does the window run from the purchase date or the activation date? The two can be days apart, so ask up front.
  • Refund channel. Whether the money goes back to the original payment method or into account credit decides how long it takes to reach you.
  • Exceptions. Look for limits such as “no refund once you've used more than X data” and read them before you buy.
WordingVerifiabilityNotes
60-day no-questions-asked refundHighDays and conditions are both explicit — you can tell for yourself whether you're still inside the window
Refund within 7 days if not satisfiedMediumThe number of days is clear, but who decides what counts as “not satisfied” isn't
Refunds available, at support's discretionLowNo boundaries, so it can't be assessed before purchase

One thing worth doing right after you buy: screenshot the terms page and note the order number and purchase date. When the refund window starts on the purchase date, that screenshot is your own basis for counting the days left.

Price structure Matters More Than the Price Itself

It's easy to stare only at the numbers when comparing, but what really matters over the long run is the relationship between price and data: does the allowance reset monthly, or stay valid indefinitely? The two structures suit two completely different usage patterns, and all three tiers can be checked directly on the pricing page.

Monthly plans: reset every month from the activation date

Monthly plans come in three tiers, with data resetting each month from the activation date. They suit people whose monthly usage is steady and roughly predictable. Unused data doesn't roll over, so pick a tier for your peak usage, not your average.

TierDataPriceReset
Monthly subscription60GB¥9.9 / monthResets monthly from the activation date
Monthly subscription250GB¥18 / monthResets monthly from the activation date
Monthly subscription500GB¥28 / monthResets monthly from the activation date

Data packs: use until it runs out, never expires

Data packs take a different approach: buy once, no expiry date, use until it runs out. Once purchased there's no renewal cycle, so there's no “forgot to cancel” problem either. For long-term use that's more practical than a discount: the data you bought isn't tied to a renewal cycle, so if you stop for a few months and come back, the balance is still there.

TierDataPriceValidity
Data pack300GB¥158Use until it runs out — never expires
Data pack1000GB¥358Use until it runs out — never expires

  • 110+Countries and regions
  • 210+Routes available
  • 60 daysNo-questions-asked refund window
  • UnlimitedSimultaneous devices

All four figures can be found directly on the pricing page and in the refund terms — no need to dig through third-party reviews. That kind of self-verifiable information is exactly what long-term use calls for.

When Monthly Billing Works Out Better

A long-term subscription isn't the default choice. In the situations below, monthly billing is actually the better fit — and what you save isn't a few yuan, it's unnecessary risk.

  • First time using this service. Spend a month confirming route quality, client usability and ticket response times before deciding whether to extend the term.
  • Uncertain usage frequency. If you only need it for business trips, travel or short-term projects during the year, a monthly subscription can be started and stopped as needed.
  • You need to change tiers flexibly. Monthly plans reset each month from the activation date, so switching tiers as usage changes is easier than with a long-term plan.
  • Predictable usage but a limited budget. Data packs run until they're used up and never expire — effectively splitting the long term into small units you can pause at any time.

The test: if you can't answer “will I use this every month for the next twelve months?”, start with monthly billing or a data pack; once you've used it two or three months in a row, consider a longer term.

Protocols and Clients: the Maintenance Side You Can't Avoid Long Term

Whether a subscription service works long term is half operations, half technical maintenance. The pace of client updates directly determines whether you can still connect smoothly after changing devices, upgrading your OS or seeing routes adjusted — the relevant steps can be checked one by one against the user guide.

Protocol Updates Are a Thermometer for Maintenance

Mainstream services usually support several protocols at once, each with trade-offs: Shadowsocks is lightweight and simple to configure; VMess supports multiple transport methods; Trojan disguises traffic as ordinary HTTPS; VLESS is leaner and often paired with something like XTLS; Hysteria2 and TUIC are built on QUIC and hold up better on lossy, weak networks. What matters for long-term use isn't how many are supported, but how quickly the client catches up when one of them sees a major version change.

Subscription Links, Routing Rules and DNS Leaks

A subscription link is essentially an address that the client polls periodically to pull and update the node list. For long-term use, three habits are worth building: don't keep the link on only one device; when you switch devices, first confirm the new client can pull it; and if the link stops working, reset it yourself in the panel instead of waiting on support.

Routing rules decide which traffic goes over international routes and which connects directly. Putting your company intranet, banks and local services in the direct list avoids unnecessary detours; after rules update, go back and confirm your custom entries are still there. DNS leaks are another easily overlooked point: if domain resolution doesn't go through the tunnel, the resolving exit exposes your local network and the browsing experience suffers too. On desktop you can check with two commands:

# Current exit IP (which route HTTP requests take)
curl -s https://ifconfig.me

# DNS resolver exit (Google's whoami service returns the requester's IP)
dig +short TXT o-o.myaddr.l.google.com @8.8.8.8
# On Windows use nslookup -type=TXT o-o.myaddr.l.google.com 8.8.8.8

If both results point to an international route exit, resolution isn't going through your local network; if the second one returns a local network address, go back into the client and check the DNS settings.

One small habit: keep your subscription link, current tier and custom routing rules in a local document. When you change devices or reinstall an OS, those few lines are much faster than scrolling back through chat history.

FAQ

Is an annual plan always cheaper than monthly?

Long-term plans usually work out cheaper per month, but only if you use the full term. Once you factor in unused months and exit cost, monthly billing or a data pack can come out ahead in some cases.

How can you tell whether a provider might shut down suddenly?

Nobody can give you a guarantee in advance. What you can do is run through the verifiable signals: are the refund terms specific, do data packs stay valid long term, are there multiple payment channels, does the client keep updating. A full set of signals doesn't mean zero risk, but at least the risk is assessable.

Who are data packs for?

People whose usage fluctuates, or who don't want to be tied to a renewal cycle. Data packs run until they're used up and never expire — no monthly charge after purchase, and no forgetting to cancel.

What should be checked regularly for long-term use?

Three things: whether the client is on the latest version, whether the subscription link still pulls properly, and whether DNS resolution still exits through an international route. If all three are fine, no extra maintenance is needed.
