eSIM Travel Tips for Thailand
Install your eSIM before your flight
Set up your HelloRoam eSIM profile at home before flying to Thailand. At Bangkok's Suvarnabhumi airport, skip the long SIM card queues. Enable data roaming in your phone settings and you are online before you reach the taxi rank.
Download offline maps for islands and temples

Use resort Wi-Fi to save data
Most Thai hotels and resorts offer free Wi-Fi. Use it for streaming and large downloads to save your HelloRoam data for day trips, markets, and temple visits where you need navigation and real-time search.
Keep your home SIM for calls
On a dual-SIM phone, keep your home SIM for voice calls and texts. Set the HelloRoam eSIM as your data line in Thailand. You stay reachable on your home number while getting fast local data speeds.
Know the emergency number in Thailand
In Thailand, the tourist police number is 1155 and the general emergency line is 191. Save these before departure. Emergency calls function on any network regardless of your data balance.
