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.
