Prepaid SIM card Bangkok from local phone companies

Within the city, several local operators have good coverage and interesting data plans. However, as visitors, we only have access to prepaid SIMs. Consider also that you may have to go through the SIM card registration process, have local currency to purchase, and locate official carrier stores in the city. We will focus on this type of plan that each operator offers.

DTAC has the largest telephone network in the country, so their Thailand tourist sim cards have several offers. As these packages are focused on tourists, they are one-time purchases, and you will not be able to renew them. If you need more days, you must buy another DTAC SIM card. They also offer benefits such as:

  • Gives access to 4G and 5G connections.

SIM Card Registration in Thailand

It’s mandatory in Thailand for people with a passport to register their mobiles. This will happen at all sales points. As mentioned, the phone is not automatically registered after you grab it. According to reports, people can’t sell ‘SIM cards’ without logging in. In addition, there are five prepaid SIM cards available per phone operator in Thailand. The restriction applies to Thai nationals and non-residents, including migrant workers and tourists. 

This makes the purchase process a bit slower when using a local operator. In this sense, Holafly is a lifesaver for travelers who want a faster solution. From their website, you can purchase and install your unlimited data package in just minutes. All you need is a compatible phone and a temporary WiFi connection.

Recommendations on the best SIM card for Bangkok

As you have noticed, there are a lot of options, both local and international, to stay connected during our trip. These recommendations are general, so you can apply them to any provider you use.

  • Try to buy your Thailand SIM card online before you get to Bangkok. This can help you save money.
  • Choose an option that allows you to use your Apps without limitations, like Google Maps.

  • You can purchase and install your service before you arrive, but you must turn on the data only when you are at your destination.
