Internet in Thailand: roaming, eSIM, local SIM and VPN explained
From the temples of Bangkok to the islands in the south, Thailand is a popular destination where a good internet connection makes the difference between smooth travel and a lot of hassle. Here's what you need to know.
Roaming with your own plan
Roaming charges for Thailand are high for most non-Asian plans, check with your provider beforehand if you're considering using your home plan.
Local SIM or eSIM?
Local SIM cards are cheap and widely available at any airport in Thailand, but an eSIM saves you the queue and the language barrier on arrival.
Costs
A local SIM or eSIM plan for two weeks typically costs between €10 and €20, Thailand is one of the more affordable destinations for data.
Do you need a VPN?
Thailand has no structural internet censorship, a VPN is optional and mainly useful for browsing safely on hotel wifi or accessing your own streaming services.
Practical tips
- Check island coverage separately, it can be weaker than on the mainland
- Grab is essential for transport and food, expect daily data use
- During monsoon season (June-October), a stable connection helps for real-time weather updates
