  • It does not have its own number, so it is not possible to make calls or SMS.
  • Another important aspect to consider is that not all cell phones are compatible with eSIM technology.

Roaming in Thailand with your local operator

Many travelers today still prefer to use their local carrier’s international roaming while traveling. The advantage of this option is that it is as easy to use. Just activate the roaming option or contact your operator to activate it. However, the disadvantage of it is that it can be quite expensive. 

The reason why roaming is so expensive is that you will usually be charged per MB or GB used, so if you don’t keep track of your data usage, the bill at the end of your trip could be quite high. Below we will tell you about two famous operators, with which their users can activate international roaming in Thailand. 

T-Mobile USA

This company from the USA allows its users to use its roaming service in Thailand. You will be charged USD 15 per MB. But if you are subscribed to the Simple Gold plans you could have unlimited text and 2G data at no extra cost.


If you are a user from Telstra, then you’ll probably be able to use the International Roaming Day Pass. The price for this plan of 500MB of data plus unlimited calls and messages is USD 10 per day.  However, this plan is only compatible with Telstra cellular services on a postpaid plan. On the other hand, you could use the pay-as-you-go plan, the price of which varies depending on the destination, but it is usually around $3 per MB.

Pocket WiFi for Internet in Thailand

A Pocket WiFi is a device that gives you your own WiFi hotspot, which you can carry with you everywhere you go and connect multiple devices to it. However, its price tends to be higher than the other options, as you will have to pay for the rental, plus shipping to your location, internet service, and sometimes insurance for the device. 

Travelers WiFi is one of the oldest companies offering Pocket WiFi. The weekly rental price is 73,4 dollars, and the service is unlimited. The company provides to ship its equipment to any country in the world. However, price variations range from $4,55 to USD 34,09, depending on the country of destination. Finally, the company charges 159,08 dollars to those who lose their equipment. 

Cello Mobile is a company from the United States. For a week’s rental, renting a Pocket WiFi is $349.99, regardless of the traveler’s destination, and the service is not entirely unlimited. Shipping for Thailand can go up to 75 dollars.  The last thing to mention is the penalty imposed by the company in the event of losing one of its devices, which is 75 USD. 

Free WiFi

Last but not least, we bring you the cheapest alternative for cellular internet since you won’t have to pay a single dime for it. We are talking about free WiFi. If you don’t have a big budget for good Internet service in Thailand, you can go to the free WiFi points that you will find in hotels, restaurants, and even shopping malls in this country. 

Although this option does not cost you any money, this would be an attractive rate if not because the connection you will access will not be ideal for things such as video calls, watching HD videos, or loading maps on Google Maps. In any case, accessing Wifi can help you perform simple tasks on your cellphone. Also, it is not a very secure option at all.
