Before you come

Before you trip to Thailand, the most important thing you can do is find out if your phone is locked or unlocked.  If you don’t know the status of your phone, one big tell is if you paid $, $99 or $199 for a top model Apple, Samsung or Nokia phone. A price that low means your phone has been subsidized, and you are likely in a 1-3 year contract where your carriers are trying to make their money back (and more) over the length of the contract.  If your phone is locked, you won’t be able to use a Thai SIM card in your phone.  If you paid $500 and up for your smartphone,  your phone is unlocked and you’ll be fine.  More about unlocking your phone.

If your phone is locked

One option is to buy a cheap unlocked phone before you come.   The other option is a pocket wifi or mifi device.  This gives your smartphone an internet connection to use all features except voice and SMS. There are now many options to rent this device in the airport.

Getting a sim before your trip

You can buy a Thai SIM card online before you come on places like Amazon or EBAY or HERE – if you have planned ahead.  Keep in mind Thai SIMs now require registration, and unless the SIM is pre-registered, you may need to do that after you land at the phone shop.

Phone with SIM or No SIM

Sim SlotAll Thailand phone networks use SIM cards.  Does your phone?  Check if your phone uses a SIM card or not.  If not, you won’t be able to get a local Thai number.  You may, however be able to use roaming if your network has a roaming agreement.

Ask your telco about Roaming

International Roaming means you use your home number and roaming usually must turned on before you leave your home country.  Call the call center and ask them to turn International Roaming on, and also ask about their charges for data and voice roaming in Thailand, as well their preferred partner network.  Data roaming can be as cheap as $10 a day, on the right network.  In other cases roaming charges can be grossly expensive.  Even when it’s a reasonable charge, the prices in Thailand are among the cheapest in the world, so likely still want a local SIM to take advantage.

 

When you get off the plane

The first thing you’ll want to do is get connected.  When you switch on your phone you’ll either be given the option to connect to one of 3 main networks in Thailand: AIS, DTAC or True.  When you connect locally, keep in mind you will be on roaming.  This means you’re paying roaming prices, which can quickly add up.  Even without a phone call you may also be on data roaming as your smartphone’s data may start in the background.

Recharging and adding data

If you finish the 7 day unlimited period, use up your calling credit or finish any data package, you’ll need to add more funds. In Thailand it’s called top up, but other places call it adding minutes, recharge, refill, load or top-up.  How much credit you need is up to your use case.

If you want to get day by day internet packages, they cost from 20 -80 Baht per day.   If you want to make calls, they cost from 1 – 3 Baht/minute for domestic and 3 to 50 Baht for International.

An internet package is a way to pre-purchase an amount of data you would expect to use in a month.  Unlimited data (at capped speeds) starts around 400 thb for the month, and goes up to about 1000 thb.  You can buy daily, monthly, weekly, volume based, time based and add on data packages.

Go here to look at the packages and how to subscribe to them.  All require you have enough credit on your phone.  Monthly packages will auto renew if you have enough credit.  If not, the package will cancel, and you’ll manually need to sign up again.
