套餐在旅途中用完了，接下来怎么办
先分清是流量用完还是有效期到期，两者的解决办法并不一样。
快速解答
- Data exhausted but still in validity can usually be topped up; expired validity usually needs a new plan.
- Do not delete the old profile before confirming a top-up is impossible: deleting removes options.

常见问题
How can I tell whether it was the data or the validity that ran out?+
Open the purchase confirmation and read two lines: the data volume and the number of days. Compare both against today's date and against the usage figure the provider reports. If the day count has passed, it expired. If you are still inside the window but the volume is at its ceiling, it is exhausted. If both still have room, the problem is more likely network attachment than the plan.
Does topping up extend the expiry date as well?+
Not always, and the rule is set by that plan's upstream supplier. Some top-ups add volume only, with the original expiry still governing; others extend the window too. Read the terms on the plan page before paying, because if the trip is longer than the validity left, a top-up may not help at all.
Can I buy a new plan while the old profile is still installed?+
Yes, if the device still has room for another profile. Keep only one enabled at a time so it stays clear which plan is being consumed, and hold on to the old profile until the new one is proven. Deleting first is an unnecessary risk, since the original QR code usually cannot be reinstalled.
There is no connection and no Wi-Fi nearby. What now?+
If you have a travelling companion, borrow their hotspot just for the installation. If not, look for a venue offering Wi-Fi to customers, or enable home-SIM roaming briefly and switch it off immediately afterwards. In the meantime, rely on offline maps and documents saved to the device, which is exactly why they are worth downloading while you still have a connection.
I bought a replacement and it still does not work. What next?+
Do not buy a third. Stop and check three things: whether the new profile is set as the line for cellular data, whether data roaming is enabled for that profile, and whether the phone is attached to a network the plan actually supports. If all three are right and it is still silent, message us with screenshots and the order reference so we can check the status on the supplier's side.
How do I stop this happening on the next trip?+
Two things work best: an expiry alert set a day early, and a data estimate built from your own real behaviour instead of a guess. After each trip, look at what you actually used per day and make that the baseline for the next one. Add two habits: always download offline maps, and keep the support contact somewhere you can open it without a connection.

Does a top-up extend the validity?+
Not always: some top-ups add volume while the original expiry still governs. Check the terms before topping up.
Can I buy a second plan alongside the old one?+
Yes, if the device can hold another profile, but enable one at a time so it stays clear which plan is being used.
