Carriers & coverage
Which networks you ride in Thailand.
In Thailand your eSIM connects on AIS, TrueMove H and dtac. These are the same physical networks a local would use — not a roaming overlay. Your phone hands off to whichever has the strongest signal where you stand, so you don't choose a carrier and you don't get stuck on a weak one.
Expected performance is 70 – 180 Mbps urban · 65 ms RTT in covered urban areas — the same band the local carrier serves its own subscribers. That is comfortable headroom for video calls, large uploads, and tethering a laptop, not a throttled tourist tier.
The reason this beats roaming is simple math. Default home-carrier roaming in Thailand runs about $20 – 40/GB, billed after your trip with no ceiling. A travel.to plan is a single charge for the data you choose, decided before you travel. Over a normal trip that is an order-of-magnitude difference, and there is no bill waiting when you get home.
Coverage detail: Three carriers per region · auto-failover below signal threshold. Failover is automatic — nothing to toggle by hand.

About Thailand
Questions people ask.
Yes. travel.to runs in Thailand on AIS, TrueMove H, and dtac — 3 partner networks in total. Your phone connects to whichever is strongest where you are, the same physical towers a local SIM would use, so coverage in Thailand is carrier-grade rather than best-effort roaming.
Thailand runs on solid 4G/LTE-Advanced, with urban speeds around 180 Mbps (70 – 180 Mbps urban · 65 ms RTT). That comfortably covers maps, messaging, calls, and streaming — you will not feel the difference for normal working-trip use.
A lot. Default home-carrier roaming in Thailand runs about $20 – 40 per GB — a single gigabyte can cost more than an entire travel.to plan, which starts at $19. You pay once, up front, for the data you choose, and there is no bill waiting when you get home.
We keep the Thailand lineup deliberately short: metered plans over 7, 14, 28 days for travelers who want a fixed bucket, plus an unlimited option for heavy use. Most people take the middle plan, which is why it is flagged as our pick.
Maps, messaging, and email sip data; video and streaming are what add up. Our Thailand plans come in 5 GB, and 15 GB, which covers a normal working trip with margin. If you tether a laptop or stream daily, size up — you can always top up mid-trip without reinstalling.
Plans for Thailand start at $19. It is a single charge — no subscription, no metered overage, no post-trip roaming bill. Stripe adds local tax at checkout based on your billing country, so the total you see is the total you pay.
Fast. ICCID assigned at checkout · QR in inbox under 90 seconds. You can install before you leave home; the eSIM stays dormant until it reaches a partner network in Thailand, then activates on its own — usually the moment you land, before you have cleared immigration.
No need. The SIM kiosks in Thailand keep limited hours (Bangkok BKK / DMK · 24h SIM counters) and you would queue at them with the rest of your flight, passport in hand. Install the travel.to eSIM before you board and you walk straight past them, already online.
Thailand sits at UTC+7 year-round. Bangkok mornings overlap European evenings — handle EU calls before lunch local. The connection holds through local peak hours, so video calls and large transfers stay reliable when you need them.
You stay connected where there is signal. Three carriers per region · auto-failover below signal threshold Your phone switches networks on its own — there is nothing to toggle by hand. Coverage is strongest across cities and major routes in Thailand.
Yes. Top-ups reuse the Thailand eSIM already on your phone — no new QR, no second install. Add data from your order page in one tap. The longest plan we list runs 28 days, and topping up extends the same line rather than starting a new one.
Full refund if the Thailand eSIM never activates. Half refund if it activates but underperforms on AIS, TrueMove H, and dtac — and if you used under 500 MB, you get the full amount back. It is one click from your dashboard, not a support ticket.
