Why eSIM here, not a local SIM
Airport SIM kiosks in Bangkok / Phuket / Chiang Mai are abundant but pushy and overpriced — single-week tourist SIMs run $15-20 with confusing top-up rules.
Free Wi-Fi: Common. 5G is strong in Bangkok and along the major beach corridors. Outlying islands and northern hill country may drop to 4G or LTE.

Common questions about Thailand
Will my eSIM work on the islands (Koh Samui, Koh Phi Phi, etc.)?
Yes, coverage on major tourist islands is reliable on 4G. Remote beaches and inland hill country may drop to 3G briefly, but you'll have signal across the popular destinations.
When does my plan's validity start in Thailand?
Validity starts when your eSIM first connects to a local Thailand network, that's usually as soon as you land and switch off airplane mode. Installing the eSIM at home days before your trip doesn't burn any days.
Can I use my phone as a Wi-Fi hotspot in Thailand?
Yes, all Esim70 plans support tethering by default with no separate daily cap. Your phone can share its data connection with a laptop, tablet, or travel companion's phone.
Will my home number still work in Thailand?
Yes, modern phones support dual-SIM. Your home SIM stays active for calls and SMS while the Esim70 eSIM handles data abroad. You can keep WhatsApp / iMessage tied to your home number too.
