常见问题
Do I need to download a new QR code after topping up?+
No. Topping up adds to the same profile that is already installed and connected, with no reinstall step involved.
If my current plan has no top-up option, what should I do?+
Buy a separate new plan instead. It is worth doing this before the existing plan's data runs out completely, to shorten the connectivity gap while switching over.
Can I buy the new plan ahead of time while the old one is still active?+
Yes. You can buy and install the new profile in advance without switching that line on, then switch over once the old plan is nearly or fully spent. This shortens the time without a connection.
Does topping up always extend the validity period?+
Not always — it depends on the specific option chosen. Some extend validity as well; others add data only, leaving the original expiry unchanged. Always read that option's own details before confirming.
If I change country mid-trip, can I use a top-up on my existing plan?+
No. A top-up only reaches the existing plan's own coverage. You need a separate new plan that covers the next destination.
