Vì sao tôi không thể nạp thêm cho gói cước?

Các lý do thường gặp: gói cước không hỗ trợ nạp thêm, hồ sơ đã hết hạn, hoặc chưa từng được kích hoạt. Một khi hồ sơ đã hết hạn, nạp thêm sẽ không khôi phục lại được — cần mua gói mới.

Topping up a plan sounds simple: press a button and more data should appear on the same profile. In practice there are three separate conditions that decide whether it actually works, and each one has its own cause and its own fix. This page keeps the three apart clearly, along with how to check each one yourself before assuming something has gone wrong on our end.

It is written for anyone whose top-up attempt was refused, anyone about to buy a plan who wants to know in advance whether it will be toppable on a future trip, and anyone mid-trip watching their data run low who needs to decide quickly between a top-up and a fresh, separate plan.

Vì sao tôi không thể nạp thêm cho gói cước?

The three main reasons a top-up gets refused

The first reason is that the plan never supported top-ups at all, no matter how many times you try, because that is a property fixed when the plan was issued. The second is that the profile has already expired, which is different from simply running out of data, since once the day limit passes the system closes that profile entirely. The third is that the profile has never been activated even once, so there is nothing existing for a top-up to attach to.

Keeping these three apart matters, because the fix for each is completely different. A plan that never supported top-ups is solved by choosing a top-up-capable plan next time. An expired profile cannot be fixed by a top-up at all — only a new plan will do. A profile that has never been activated needs to be activated successfully first before there is anything to add to.

Check whether your plan supports top-up at all

Every plan page carries a spec line that states 'Top-up available' with a value of 'Yes' or 'No'. Check that line before every purchase, especially if you have previously bought a plan for a different destination that did support top-ups, since the same provider often sells both types side by side, and the cheaper option frequently trades away top-up support for its lower price.

If you are unsure which type your current plan is, your order always records this exactly as it stood at purchase. Open the order history page or the confirmation email to see the value, rather than guessing from memory or from a different destination's plan you bought before, since two plans can differ even when they look similar on the page.

Expired versus never activated: two different states

The plan page also carries a line called 'Install window', stating how many days the profile has to be activated successfully after purchase. Miss that window without ever connecting to the destination network even once, and the profile moves into a state that no longer works, even though it was never actually used. This is a different state from expiring after use, but the end result is the same: no top-up is possible.

A common confusion is assuming that as long as the plan has never been 'used', no clock is running. That is true of the validity clock itself for a first-connection plan, but the window to activate it for the first time is a separate condition, and it is often shorter than people expect. Read both lines on the plan page separately — do not treat them as the same rule.

Why a top-up cannot revive an expired profile

A top-up only works on a profile that is still in an active state. Once a profile has expired, the system closes that line and withdraws its right to use the network entirely, so there is no longer any destination for extra data to attach to, whether the top-up would have extended the same window or arrived as a fresh data block.

That is why the short answer states plainly that a top-up will not revive it, and why the only real fix is a new plan, whether for the same destination or a different one. A new plan carries its own clock, starting according to whichever activation type is stated on that plan's own page.

Topping up versus buying a new plan: not the same thing

A successful top-up usually means adding data onto the profile already installed, without scanning a new QR or installing anything else. It suits being mid-trip with days still remaining but data running low. Buying a new plan, by contrast, creates an entirely separate profile, which needs its own QR scan and installs as a second, distinct line.

The table below compares the two options directly, so you can decide quickly whenever data is genuinely running low mid-trip.

How to tell which state your profile is actually in

Before concluding this is a system problem, check the actual state on your phone and in your account first, since the menu to look at differs slightly between iOS and Android, and can vary further by handset model or operating system version. The steps below are a general guide that applies to most phones.

  1. 1iOS: check the line's statusOpen Settings → Mobile Service / Cellular and tap the line that is this plan's eSIM. If that line has disappeared from the list or shows no service, that usually means the profile has expired. The exact wording of this menu can vary slightly by your iOS version.
  2. 2Android: check the line's statusOpen Settings → Network & internet → SIMs and tap this plan's eSIM profile. If it shows as inactive or never finds a network at all, that can mean either expiry or that it has never been activated successfully. Menu names and positions vary by handset manufacturer and Android version.
  3. 3Check your order pageOpen the order history page in your account to see whether this plan's 'Top-up available' field reads 'Yes' or 'No', and to see the deadline for its install window.
  4. 4If you still cannot tell which state it is inSave a screenshot of the network menu and the order page, then contact the team with your order number so they can confirm exactly which state it is in.
The most common misunderstanding is assuming a top-up can revive a profile that has already expired, whatever type of plan it is. An expired profile needs a brand-new plan — a top-up only works on a profile that is still active.

If you can't top up and data is about to run out mid-trip

If you find the plan never supported top-ups in the first place, the remaining option is to buy a new, separate plan, which installs as an additional profile on the same phone as normal, without affecting the one already in use. Choose a data amount that suits the days left in the trip rather than simply repeating the original purchase.

If you are unsure how much to buy for the days remaining, the data calculator tool on the site can give a rough estimate based on your own usage habits before you commit to a purchase.

Choosing a top-up-friendly plan for next time

If you often end up using more data than planned, or want a fallback option mid-trip, look for a plan marked 'Top-up available: Yes' at the point of purchase, rather than solving this once data is already running low. Checking that one line takes only a few seconds but removes most of the problems that could otherwise come up mid-trip.

Choosing a top-up-capable plan does not mean buying a larger data amount up front — it simply keeps an option available if it turns out to be needed. You can still pick the starting amount based on your genuinely expected usage as normal.

If you buy extra data while the profile is still active

A successful top-up may either extend the existing window or arrive as a fresh data block with its own separate expiry, depending on the specific top-up option you choose at the time. Always read that option's details before confirming, since the two behave differently when planning the days left in your trip.

After a top-up succeeds, check the order page or the phone's network menu again to confirm the data balance and expiry updated as expected. If the figures do not look right, save a screenshot and contact the team with your order number.

Before you rely on topping up mid-trip, check these

  • Whether your plan page's 'Top-up available' line says 'Yes' or 'No'
  • Whether the profile is still active, not already expired
  • Whether the profile has already been successfully activated, rather than still sitting in an unstarted install window
  • The actual remaining data against the days left in the trip, before deciding between a top-up and a new plan
  • Your order number ready, in case the team needs to check the status for you

Whether a plan can be topped up is fixed when the plan itself is created

Many people assume topping up is an optional service a shop can switch on or off on request. It is not. The ability to top up is a property built into the plan from the outset, set by the supplier behind it and the arrangements with networks in the destination country. When you buy, you are buying a plan that either carries that property or does not — it is not something added afterwards on request.

The practical consequence is that if your plan does not support top-ups, nobody in the chain can change it — not our team and not the supplier's support desk. That sounds rigid, but it lets you decide much faster, because instead of spending time appealing you move straight to the route that works: buying a new plan as a separate profile.

Two entirely different symptoms: no button to press, and a button that fails

The phrase "I can't top up" covers two very different situations. In the first, you cannot find the option at all — no button, no menu, nothing to press. That almost always means the plan does not support it, or the profile is in a state that no longer accepts one. In the second, the button is there, you press it, and the process collapses partway. That is a payment or connection matter rather than a question of plan terms.

What you seeThe most likely causeBước tiếp theo
No top-up option appears at allThe plan does not support it, or the profile has expiredBuy a new plan as another profile rather than retrying
The option is greyed out and cannot be tappedThe profile was never activated, or is between statesGet the phone to connect to the destination network first
It says the payment was unsuccessfulThe issue is with the card or bank, not the plan's termsCheck with the bank, or use another method shown at checkout
The page spins, then throws you backAn unstable connection, or a public Wi-Fi login page in the wayMove to a more stable connection and start again from the beginning
The top-up succeeds but the data does not appearIt needs time to update, or the phone has not re-registeredToggle flight mode once, wait a little, and check again

Identify the symptom first and you will know whether to talk to the bank, to us, or to nobody at all

If your symptom is a failed payment, that is an entirely separate matter from top-up eligibility. Your plan may well support top-ups while the card is being refused. Fix the payment side first, then return to the eligibility question.

A top-up extends the coverage you had; it is not a ticket to a new country

A frequent misreading is that a top-up is a neutral block of data usable anywhere. In fact it goes into the existing profile, so it stays inside that plan's coverage. If you bought a single-country plan and then travel onward, a top-up will not make it work in the new country — you need a plan whose coverage includes that country instead.

This is why people covering several countries in one trip usually pick a regional plan from the start rather than buying country by country and hoping to extend. That decision is far easier while planning, when the whole route is still in front of you, than at a border crossing with no working connection.

If you have already deleted the profile from the phone

Deleting a profile is something people do without thinking twice — tidying up the SIM menu, handing a phone back to a shop, resetting a device to factory settings. The difficulty is that once it is deleted, it usually cannot be reinstalled with the original code, and with no profile on the device a top-up has nowhere to go, even on a plan that supports one.

Before resetting a phone, switching devices, or clearing out a profile you think is unused, pause and ask whether it still holds data or days. Deletion is generally irreversible, and it is a common way people lose a plan they had not finished using.

Several profiles on one phone, and topping up the wrong one

Frequent travellers accumulate old profiles from earlier trips that were never removed. When the moment comes to top up, the names in the menu often look near-identical, because several were labelled after the same underlying supplier. People end up adding to a profile that expired months ago, or activating the wrong one mid-trip.

  1. 1Rename each profile the moment you install itUse the country and month, such as Japan April, so several of them stay distinguishable. Where the rename control sits differs by brand and OS version.
  2. 2Match against the order email before pressing top upOpen the confirmation email for the plan you are actually using and check it is the same order as the profile you are about to add to.
  3. 3Confirm that profile is the line currently carrying dataIn the line settings, see which line is set as the mobile data line — that is the profile genuinely in use.
  4. 4Delete only the profiles you are certain have expiredIt reduces confusion next trip, but be sure no data or days remain, because deletion is usually final.
  5. 5Keep the order emails in one folderWhen you need to check back or contact the team, the order number is immediately to hand without a long search over a slow connection.

Time zones and the feeling that there was still a day left

A common protest is: I still have a day left, so why can I not top up? The explanation is usually the time zone. Validity is counted against the system's own reference time rather than the clock on your screen, which shifts to wherever you are standing. Fly across several zones and the gap becomes hours — and on the final day, that is the difference between in time and too late.

The safe approach is not to plan on using the last day to its final minute. If you know you will need data right up to the end of the trip, settle the extra-data question at least a day before, not on the morning of the flight home. A one-day margin resolves the whole issue without needing to understand the time-zone details at all.

Topping up on an unstable connection or behind a public Wi-Fi login

A top-up is a full online transaction: a payment, a confirmation, and a status update coming back. If the connection stutters midway, the result can be an ambiguous state that looks like failure although it may have gone through. Public Wi-Fi that requires you to accept terms before use causes this most often, because it drops the connection silently while you are mid-transaction.

If that happens, do not immediately press top up again. Check your email for a confirmation and look at your order page once more. Pressing again straight away can create overlapping transactions, which are harder to untangle than a short wait and a proper check.

Ordering with a different email from the original purchase

An order is tied to the email used when it was placed. Come back with a different address — the work one instead of the personal one — and the system reads it as a fresh, unrelated purchase. You will not see the earlier plan's history, and the confirmation will land in an inbox you are not watching.

If you suspect the wrong address was used, search every inbox you use regularly for terms relating to the order, and check the spam folder too. If it genuinely cannot be found, message the team with all the addresses it might have been, so we can help locate the order.

The leftover data when you buy a new plan

When you have to buy a new plan because a top-up is not possible, the next question is what happens to whatever remained in the old one. The plain answer is that it stays with the old profile and lives by that profile's terms. It does not merge into the new plan, because the two are separate profiles with separate clocks.

In practice, if the old profile has not expired and still holds data, you can switch back and finish it before moving to the new one. The thing to watch is changing the data line in settings to match whichever profile you intend to use, or you will draw on the wrong one and conclude that the new plan is disappearing unusually fast.

Ưu điểm

  • Two shorter plans let you adjust to real usage partway through the trip
  • If you use less than expected, you are not paying up front for the whole allowance
  • It limits the damage if one profile has trouble, because another remains

Nhược điểm

  • It means another installation and line switch mid-trip
  • Get the timing wrong and there is a gap with no connection at the changeover
  • It requires paying while abroad, which is fiddlier than paying at home

Planning so that you never need to rely on a top-up

The best way to handle top-up limits is to design the trip so you never depend on one. Start by estimating your usage from a previous trip rather than from impressions, then allow extra for long travel days and days when you have to work. After that, choose a plan covering every country on the route rather than only the first.

  • Check before buying whether the plan states that top-ups are available; do not assume
  • Look at when validity starts counting and whether that matches your dates
  • Confirm coverage includes every country you will stop in, including layovers where you leave the airport
  • Allow more data for travel days than for ordinary ones
  • Keep the order email and number reachable without a connection — a screenshot is enough
  • Decide about extra data at least a day ahead, not at zero
The question to ask before buyingWhy it matters
Does this plan allow top-ups?If not, the only mid-trip route is a new profile, which is better known in advance
Which countries does it cover?A top-up does not extend coverage, so it must be complete at purchase
When does validity start counting?If it starts earlier than you assumed, the last day arrives before you fly home
Is a connection needed to install it?It decides whether to install at home or wait until arrival
How can the remaining balance be checked?Without a way to check, you find out too late that data is running low

These five questions take under a minute and remove most mid-trip trouble

If you are unsure about size or coverage, use the data calculator to estimate the size, then browse plans by region to compare coverage. Between them they answer most of the questions that push people into needing a top-up midway.

If a top-up is impossible and you are hours away from having no connection

In an urgent moment the sequence that works is: get any temporary connection first — the accommodation's Wi-Fi, a restaurant, a companion's hotspot — then buy a plan covering the country you are in and install it as an additional profile. Do not delete the old profile at this point: if something goes wrong with the new one, you would be left with nothing.

Once it is installed, set the mobile data line to the new profile and confirm the phone actually registers on a network before you leave the Wi-Fi. That last step matters, because a successful install and a working connection are two different things, and you want to find out while a remedy is still within reach.

Câu hỏi thường gặp

If the top-up option does not even appear when I try, what does that mean?+

It usually means the plan never supported top-ups at all, or the profile has already expired. Check the 'Top-up available' line on your order to confirm which it is.

I topped up but the data did not increase — what should I do?+

Check the order page and the phone's network menu again first. If it still does not match what it should show, save a screenshot and contact the team with your order number.

Can I top up a profile that has never been activated at all?+

No, since there is no active profile yet for a top-up to attach to. It needs to be activated successfully first, by letting the phone actually connect to the destination network, before a top-up can even be considered.

Can I buy a new plan to use alongside one that has already expired?+

Yes. The new plan installs as a completely separate profile with its own clock, entirely unconnected to the expired one already sitting on your phone.

For a top-up-capable plan, does the top-up itself have its own separate expiry?+

It depends on the specific top-up option chosen at the time: some extend the existing window, others arrive as a fresh data block with their own separate expiry. Always read the details before confirming.

How can I know in advance whether the plan I am about to buy supports top-ups?+

Look at the 'Top-up available' line on that plan's page before you buy — it clearly states 'Yes' or 'No'. Do not assume it based on a different destination's plan you bought previously.

Can the team enable top-ups on a plan that does not support them?+

No, because that property is built into the plan when it is created rather than being a switch to flip afterwards. What we can do is confirm the status of your order and point you to a plan that suits what you need from here.

Does topping up move the plan's expiry date as well?+

It depends on the option you pick at the time. Some add only data while the expiry stays where it was; others carry different terms. Read that option's details before confirming, because there is no single rule covering every plan.

If I change phone mid-trip, does the profile and its top-up follow?+

An eSIM profile is tied to the device it was installed on and does not follow you automatically. Whether it can be moved depends on the plan and the supplier behind it, and in many cases it cannot. If you expect to change handsets during a trip, ask us before buying — and do not delete the profile from the old phone yet.

If I buy a new plan while the old one is still valid, will they clash?+

They do not clash: each is a separate profile with its own clock, and the phone draws only on whichever you set as the mobile data line. The thing to watch is remembering to switch, or you will carry on using the old one without realising.

If the money was taken but the data never arrived, what should I do?+

Do not immediately top up again. Toggle flight mode once and give it a short wait, since the status sometimes needs time to update. If it still has not appeared, keep screenshots of the payment record and the order page, then message the team on LINE or by email with your order number.
