Thailand eSIM — Common Questions

Does eSIM work on Thai islands like Koh Samui?
Yes, the major islands are well-covered. Koh Samui and Koh Phangan have solid AIS and True Move H 4G. Smaller, less-touristed islands can have limited signal.
Is coverage good in northern Thailand?
Chiang Mai is well-served with 4G and some 5G. Pai and Mae Hong Son are covered in town but signal drops in mountain valleys.
Do I need a Thai number to use apps like Grab?
No. Grab Thailand accepts international phone numbers for registration. You just need a working data connection from your eSIM.
Does eSIM work in Phuket and surrounding islands?
Yes. Phuket town and all major beach areas have excellent 4G. The Similan Islands have limited coverage as they're in a protected marine national park.
