Frequently asked questions

Yes. Roamis connects through major Thai networks like AIS and TrueMove, covering Bangkok, Chiang Mai, Phuket, Pattaya, Krabi and most urban and island areas.

Korean passport holders can enter Thailand visa-free for 90 days for tourism (as of 2026). Your Roamis eSIM gets you online for immigration, Grab and hotel check-in the moment you land. Confirm current rules before you fly.

Validity starts when you install and connect in Thailand — not when you buy. Set it up before you fly and it begins counting from your first connection on arrival.

Coverage is generally good on the main tourist islands and near ferry piers. Remote beaches and jungle treks can be weak, so we recommend downloading offline maps in advance.

Yes, you can share your connection to a laptop or another device. Heavy tethering may be subject to the fair-use terms shown on the plan.

No. The eSIM runs alongside your existing SIM, so you keep your number for calls and texts while using Roamis for data.
