It depends on when you will have the documents a local service asks for, and that varies by country and by university. Many students cover the settling-in stretch until registration is done and they have proof of address. Allowing slightly longer than you expect is usually more comfortable, because first-week paperwork tends to run slower than planned. If unsure, ask the international student office how long the process normally takes.

Many students still do, because banks and other services tie verification to the original number. The best sequence is to move that verification onto an authenticator app before departure, then decide whether to keep the number. How to keep it alive from abroad, and what that costs, is set by your own operator — ask them directly.

Once you have whatever documents that country requires and you know which area you will live in and how you will get around — usually after registration and moving in. Documentation rules belong to each country and can change, so check official sources for the destination or ask the international student office rather than relying only on what previous students remember, since the rules may have moved.

It depends on whether that plan permits tethering, which is stated in the plan's own details — check before buying if you intend to rely on it. Also worth knowing: laptops use far more in the background than phones, between system updates and file sync. Set the connection as metered and turn off automatic updates before you tether.

Check three things in order: that the line you enabled is set as the mobile data line, that data roaming is on for that line, and then cycle aeroplane mode and restart the phone. If it still fails, do not delete the profile — it usually cannot be reinstalled. Find airport Wi-Fi and message us on LINE or by email with your phone model, OS version and exactly what the screen shows.

Any prices and offers that exist are shown on the plan pages themselves. We do not quote figures in articles because they change and differ by plan and destination. If you are planning a period of study and want help comparing options for your dates and country, send the details on LINE or by email and we will compare what is actually available at the time.
