How EE actually works in Thailand
Thailand has three main carriers: AIS, True Corp, and dtac. EE’s roaming partners route to AIS, the strongest 5G network. Solid 5G in Bangkok, Phuket, Pattaya, Chiang Mai. 4G LTE everywhere else including Koh Samui, Koh Phangan, Koh Tao, and Phi Phi.
Speeds in tourist areas typically 30-100 Mbps on 5G, 15-40 Mbps on 4G. Roam Abroad triggers automatically on first use; EE sends an SMS confirming.

When EE Roam Abroad is the right call
- You make a lot of voice calls — Roam Abroad includes calls; the eSIM is data-only
- Single-SIM phone where you can’t dual-SIM
- Corporate EE plan with Roam Abroad comped
- You want zero setup — Roam Abroad activates automatically
Note: unlike most non-EU destinations, in Thailand the eSIM is cheaper even for a 1-day trip. There’s no clear “Roam Abroad wins” scenario for Thailand on price alone.

Common questions
Can I buy a SIM at Suvarnabhumi (BKK) or Don Muang (DMK)?
Yes — AIS, True, dtac all have airport kiosks. Tourist SIMs run THB 200-500 (£4.50-12) for 5-15GB packages and require a passport. Reliable but you’ll queue 20-30 minutes. The eSIM is significantly easier.
Should I install LINE before going?
LINE is the dominant messaging app in Thailand — every hotel, tour guide, taxi driver uses it. WhatsApp works for tourist-facing businesses but LINE is better for local communication. Free. Install before flying.
Will I have signal on Koh Samui / Phi Phi / Phuket?
Yes on all major tourist islands and routes between them. AIS has thorough coverage of southern Thailand. Speeds drop on smaller islands but you’ll have 4G almost everywhere a tourist goes.
Does Grab work on the eSIM?
Yes. Grab uses your account login, not your phone number. Works on any data connection.
The bottom line
For any Thailand trip including a single day, an eSIM beats EE Roam Abroad on price. A 2-week Thailand trip: £6.70 with Travelren versus £70 with Roam Abroad — £63 saved on cocktails for the week.
