FAQ

How much more do regional plans cost vs single-country?

About 30–60% more per GB. For 1–2 countries go single-country; for 3+ the regional plan wins overall.

Are Myanmar and Laos covered?

Most regional plans include Laos; Myanmar appears less often and local conditions affect service — verify per plan if it's on your route.

Anything to do at each border?

No — it registers on the local network automatically. If nothing after 5 minutes, toggle airplane mode once.
