Practical Tips for Staying Connected in Thailand
How much data do I need for Thailand?
For a 7-10 day holiday, 5-10GB covers navigation, Grab rides, WhatsApp, social media, and light browsing. For 2+ weeks or heavy use (video calls, streaming), go for 20GB. Download maps and Netflix episodes on hotel Wi-Fi to save your allowance.
Does it work on the islands?
Yes. Coverage is strong across popular islands including Phuket, Koh Samui, Koh Phangan, Koh Lanta, and Koh Phi Phi. Very small or remote islands may have limited coverage, but this affects all carriers.
Which apps should I download before my trip?
Grab (taxis and food delivery), Google Maps (offline maps available too), Google Translate (has Thai language support with camera translation), and LINE (popular messaging app in Thailand if you need to contact local businesses).
Can I share data with my travel partner?
Yes, use your phone’s hotspot feature. For couples or small groups on a short trip, one 10GB plan with hotspot sharing can work. For longer trips, separate plans are more practical.
What about calls?
Go Simly eSIMs are data-only. Use WhatsApp, FaceTime, or Skype for calls — they’re free over data. Your existing SIM stays active for receiving calls and texts on your home number.
