Thailand: before you go
Internet
Roaming depends on your operator — consider an eSIM
EU roaming rules only cover SIM cards from EU and EEA countries. Check your operator's rates or buy a local eSIM.
Documents
Usually a passport — check the requirements
Check the entry rules (visas, passport validity) in your own country's official travel advice.
Healthcare
The EHIC is not valid
You pay for treatment yourself — travel insurance is a must.
Money
Local currency: THB
1 THB ≈ £0.0225 (average NBP rate)
