Overall, the connection is very good. There was one spot in Bangkok where the reception was poor, but maybe not all reception there is good. I'm happy with the product and recommend it.

The internet connection was excellent everywhere: Bangkok, Pattaya, Koh Samet, and Koh Larn. Calls were also excellent, and logging in to Thai apps by phone number worked just as well. Overall, no complaints, everything was perfect! We recommend it.

Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.
