- Check your phone supports eSIM and is unlocked (iPhone XS and later, Pixel 3 and later, most recent Samsung Galaxy S and Z models).
- Buy a plan for your destination before you travel.
- Install it at home over Wi-Fi by scanning the QR code or tapping install in the provider's app.
- When you land, switch mobile data to the eSIM and turn data roaming on for that line only. Keep your UK SIM active for calls and texts if you want, with its data turned off.
Questions
Do I need an eSIM for Thailand? Not strictly, but it is usually far cheaper than roaming on a UK plan. Strong 4G and 5G in cities and islands like Phuket and Koh Samui.
When should I install my Thailand eSIM? At home, before you fly, while you have Wi-Fi. Switch it on for data when you land.
