Get up to 50% off your first eSIM
No coupon-site scavenger hunt, no expired codes copied from forum threads — WELCOME is our own welcome code, published here at the source. Enter it on your first order in the Thailand eSIM app and land in Bangkok with your plan already discounted.
WELCOME 
How to redeem it
-
Get the Thailand eSIM app on your phone — easiest over home Wi-Fi, before the airport rush.
-
Pick the Thailand data plan that matches your trip, whether it's a week on Koh Samui or a winter working from Chiang Mai.
-
Type WELCOME in the promo code field at checkout and pay the discounted price. Your eSIM is ready before you take off.
The honest fine print: WELCOME works on your first order in the app. The discount is drawn at random when you redeem it — anywhere up to 50%, never a guaranteed flat rate. And the code has no expiry date, so there is no countdown to race.
