Tips for Using eSIMs in Thailand

Want to make the most of your Thailand eSIM plan? Follow these expert travel tech tips:

✅ Use Data Wisely

Even on an unlimited plan, it’s smart to keep tabs on your usage in case of speed throttling under FUP.

✅ Download Offline Maps

Apps like Google Maps and Grab work best online, but download offline versions for backup.

✅ Battery Life Matters

Using 5G or LTE constantly can drain your phone faster. Carry a power bank while you're out exploring.

✅ Choose Apps Smartly

Some travel apps (like WhatsApp, Google Translate, XE Currency) are data-friendly and incredibly useful.

✅ Use Limited Data Plan If You Need Tethering

Planning to use your phone as a hotspot? Choose a limited data plan, since unlimited ones don’t allow tethering.
