Thailand 3GB 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
