Frequently asked questions.
Answers to common setup and buying questions.
How do I pick the right Thailand eSIM?
Start with how many days you'll be away, then your likely data use. The 100 MB option is the cheapest listed plan, but it leaves almost no room for images or downloads, so it is rarely the best value for more than one day. The practical recommendations for a short stay are to compare 3 GB for 15 days at €2.19 with 10 GB for 30 days at €6.89; these data plans differ mainly in total allowance and validity, so pick the best fit for your usage. The best price is simply the plan whose allowance and validity match your trip, and the most affordable choice is usually the one you won't have to replace. Keep large backups for Wi-Fi.
Which networks and mobile technologies does it use?
The network list covers AIS Thailand and DTAC Thailand, both of which support 4G/LTE and 5G. Actual access depends on your device, location and conditions, and no carrier here earns a blanket best coverage claim. A signal on the coast doesn't promise reception during a boat crossing.
Will my phone work with this eSIM?
Confirm your exact phone model and regional variant supports eSIM and is network unlocked. On iPhone, open Settings, then General, then About and check Carrier Lock: No SIM restrictions means it's unlocked. On a Pixel, go to Settings, Network & internet, SIMs, Add SIM, Set up an eSIM. For other Android models, the compatible phones list and setup path vary, so check the maker's guide before buying. Both iOS and Android install the eSIM card from a QR code or carrier app over Wi-Fi.
When should I install and activate it?
Install over reliable Wi-Fi and keep the instructions where they open offline. Follow the activation steps supplied with your plan before switching the line on: instant installation is not promised, and installing the profile may not start your validity, which depends on the plan's own instructions. On arrival, select the travel eSIM for mobile data and apply the roaming and APN settings specified for it.
Can I still use WhatsApp and get bank codes?
Your existing WhatsApp account works over the eSIM's internet connection, and so do calls and uploads on apps like YouTube if your allowance allows. Standard SMS and bank verification codes still rely on your regular SIM, bank and carrier, because this data-only plan adds no local phone number. Check your home carrier's charges if you keep that line on.
Can I tether a laptop to this eSIM?
The listed networks support hotspot. Any device you connect draws from the same data allowance. The data hotspot and tethering features let a laptop share the same allowance. Automatic updates, video meetings and cloud backups on connected devices can eat a large part of a fixed total, so pause those transfers or use Wi-Fi when you can.
Does the allowance renew each day, or is it unlimited?
Each plan card shows a fixed total allowance for its validity period. It is not unlimited and does not reset each day; a 30-day plan is one block of data, not a monthly subscription that refills. Tethering and hotspot devices draw from that same total, and a longer validity window does not add data. The listed features are fixed at purchase, and any no contract claim should be confirmed in the purchase terms rather than assumed.
Does it work in neighbouring countries?
No. These offers cover Thailand only, so arrange separate coverage for onward destinations and check the stated country list of any regional plan. A connection close to a border does not mean the neighbouring country is covered.
Can I top up or extend a plan?
No top up amounts are published on this page, so the practical route is to choose an available plan that covers the extra data and days you need. Follow the instructions for that purchase; don't assume it extends an existing plan, reuses its profile or carries over remaining data. Keep the installed profile while you sort out any connection issue.
What should I check when data won't connect?
Confirm you're in Thailand, the eSIM line is enabled and set for mobile data, and the plan still has data and validity left. Follow the supplied roaming and APN instructions, toggle airplane mode or restart, then try another spot, since service quality varies by location and the chosen operator's network. Keep the profile installed and have your phone model, location and order reference ready when asking for help.
How do I stop my regular SIM from using data?
Set the travel line as your mobile data line and turn off automatic data switching. Keep data roaming off on your regular SIM, and apply any required roaming setting only to the travel line. Calls and texts on your regular number stay subject to your home carrier's terms.
What should I keep in mind before a refund request?
Keep the order reference, installation details and a description of the problem. Refund eligibility depends on the purchase conditions and whether the plan has been activated or used, so read the applicable policy and the pricing terms before you buy. Don't delete an installed eSIM as your first troubleshooting move.
Will there be data on a Phuket boat trip?
The plan covers Thailand, but it does not guarantee reception at sea. Download the boat ticket and pier location before boarding, agree a return pickup, and send time-sensitive messages while still ashore. This gap catches tourists on holiday and family vacations alike: buying more data does not improve the network's reach.
Getting online across Thailand
A Thailand eSIM sized to your trip
A rail link from Bangkok airport, a temple run in Chiang Mai and a boat day out of Phuket each ask for different planning. Keep the booking you need next where you can open it without signal. The eSIM is a virtual sim card you install digitally on a compatible, unlocked phone, so there's no physical SIM to swap when you land.
The 100 MB and 500 MB options are small allowances for light use; for a one-day (1 day) stopover, 100 MB may be enough. Across a short stay of several days, compare 1 GB for 7 days at €0.85 with 3 GB for 15 days at €2.19. Choose more data if you expect video calls or regular tethering.
For 2 weeks (14 days) away, 3 GB for 15 days at €2.19 usually fits. For one month, 10 GB for 30 days costs €6.89, but 30 days is not always a calendar month and none of these is a monthly subscription that renews. The 50 GB for 180 days option carries a longer validity window yet remains a single total allowance. Compare days and data before you buy.
Plan for the gaps between connections.
The listed networks, AIS Thailand and DTAC Thailand, carry 4G/LTE and 5G. What you actually get depends on your phone, location and network conditions. A strong signal on the coast says nothing about reception mid-crossing.
within reach.Wat Arun, Bangkok
Bangkok: sort the airport leg before the train.
Landing at Suvarnabhumi, weigh the Airport Rail Link against the airport's own bus and taxi listings. Save your hotel address in Thai and your arrival terminal, and decide the final leg of the trip, not just the airport transfer.
The transfer only begins a city day. Before setting off toward Wat Arun, pin your destination and settle which riverbank your group will meet on. A photo of the meeting spot is easier to follow than a temple name.
Use your data to pull up the next booking or check a transport operator's current departures. The travel eSIM provides the connection; fares and any app sign-up stay separate.
Save before you goHotel address in Thai, airport pickup instructions and the station or riverbank meeting point for the next leg.
Chiang Mai: fix the return before you climb.
Wat Phra That Doi Suthep is its own outing, not part of the old city. Give the driver your accommodation entrance and agree where you'll regroup after the temple, especially if people wander at different speeds.
Check the tourism authority's attraction details before leaving. Save the temple pin and return plan while you still have a connection; hills, buildings and local network conditions can cut mobile service.
Back in town, a small allowance covers messages and directions if you leave video uploads for Wi-Fi. A larger plan just gives you more data for photos; it doesn't extend the network's reach.
Save before you goDoi Suthep pickup point, agreed return time and a copy of your accommodation address.
Phuket: a beach name isn't a pickup point.
Patong, Karon and Rawai sit far apart on a big island. Confirm the exact hotel or tour pickup pin before you leave the airport instead of asking for a transfer just to Phuket.
For a boat trip, ask the operator for the pier, check-in time and return plan. Download the ticket and send final messages while still ashore; these plans don't promise a signal at sea.
Reconfirm the trip with the operator before heading to the pier. Leave enough data for afternoon pickup changes, and use hotel Wi-Fi for full photo backups.
Save before you goBoat voucher, named pier, pickup details and return instructions, saved so they open without a connection.
