Wi-Fi, SIM & Mobile Rental in Pattaya

• Your phone is SIM-locked or does not support eSIM
• You want one router to connect several devices for your family or travel companions
• You want to keep your Japanese number and add local data only
• You need a phone with a Thai number for booking restaurants or clinics and contacting drivers
• You are not confident with settings and want to be connected from the day you arrive

There are four usual ways to stay connected: a SIM, an eSIM, pocket Wi-Fi or a rental phone. We rent routers and phones. After hearing how you will use them, we may suggest a SIM or eSIM instead if that suits you better.

SIM prices are the usual range for tourist plans as of September 2026 and change with promotions and seasons. For a solo traveller with an unlocked phone, a SIM or eSIM is simplest. For a family sharing one connection, or for connecting a laptop for work, a router is a better fit.

• AIS: the largest carrier, with a reputation for good coverage on islands and in rural areas as well as cities
• True (TrueMove H): merged with dtac in 2023 and has been integrating the two networks. Reliable in cities such as Pattaya
• dtac: now part of the True group and still selling tourist plans

All three have counters in the arrivals halls at Suvarnabhumi and Don Mueang. You register with your passport when you buy, and at busy times you may queue for 10 to 30 minutes. Late-night flights can also land into long queues. Counter staff usually swap the SIM and check that it works, so put the Japanese SIM they remove in a small pouch and keep it safe until you fly home.

If you need to call a driver or contact family as soon as you land, set up an eSIM before you fly or collect one of our routers so you can skip the airport queue. If you are also booking our airport transfer, ask us about handing over the device then.

Here is a rough guide to data use. It varies widely with video quality and app settings.

If you mostly use maps, ride-hailing apps and messaging, about 1 GB a day is often enough. By saving video for hotel Wi-Fi, many visitors fit a week of sightseeing into a 10 to 15 GB plan. If you join video meetings for work or tether a laptop, we recommend an unlimited plan or a router.

What we do

• Ask about your length of stay and usage, then suggest a router, a phone, or a SIM or eSIM
• When you collect the device, we check the connection with you and explain how to use it
• If you cannot connect, message us on LINE and we will walk you through the checks

What you need to do

• Tell us the date, time and place for pick-up and return
• Keep the device charged and look after it so it is not lost
• Return it by the agreed date. If your stay is extended, let us know early

• A SIM bought at the airport does not work: a SIM-locked phone cannot use a Thai SIM. Check your unlock status with your Japanese carrier before you travel
• The eSIM QR code will not scan: a phone cannot scan a QR code shown on its own screen. Display it on another device or print it for a quick setup
• The connection suddenly stops: tourist SIMs and eSIMs stop when either the days or the data run out. Note the expiry and allowance when you buy, and top up if needed
• Bank or payment app codes do not arrive: verification codes often go to your Japanese number, so keeping your Japanese SIM in place helps avoid getting stuck
• The router runs out of battery: on full days out, carrying a power bank is a good idea

If you are unsure which to choose, tell us your length of stay, how many people are travelling, your phone model and whether you need it for work. We will suggest a router, a phone, or a SIM or eSIM on that basis.
