Price per GB in Thailand: Which eSIM Plan Is Best?

If you’re going on a short trip of 5-10 days and only need mobile data outside your hotel, the 3 GB basic plan is a great choice (~$3.66/GB). However, if you need data for remote work, streaming movies, or staying active on social media, we recommend opting for the larger packages. They offer the best value per GB: 20 GB (~$2.25/GB) or 50 GB (~$2/GB).

Benefit #1: Mobile Coverage Across 98,99% of Thailand

Mobile coverage is available throughout almost all of Thailand. The signal is especially strong in Bangkok, Chiang Mai, Pattaya, and Hat Yai. Stable coverage is also common on Phuket, the largest and most popular tourist island, as well as on smaller destinations like Koh Lanta, Koh Phi Phi, and Koh Tao. In most areas, all three local operators we work with, TrueMove H, AIS, and DTAC, provide service. In more remote locations only one or two networks may be available, but you can switch manually if needed.

Benefit #2: High-Speed Mobile Internet via travel eSIM in Thailand

Average download speeds range from 30.2 to 31.3 Mbps, while uploads vary from 5.8 to 12.0 Mbps. You can get some of the best 5G performance in most locations by connecting to AIS. This operator also offers the highest upload rate at 12 Mbps.

Benefit #3: Perfect for Family Trips

We offer a variety of large data packages for Thailand – 15 GB, 20 GB, and 50 GB. Data sharing is also fully supported, so you can buy a big package and use a smartphone as a hotspot in the evening, for example, to watch a movie together on a laptop. Large packages are also a great way to save money, as they give you the lowest price per GB.
