Bangkok and Phuket sibeh crowded, sometimes the Wi-Fi will spin like sotong kena goreng. But if go ulu places with fewer people, the connection damn fast one.★

Super convenient to have it ready when landing. It does what it says it will do. I would definitely trust this and use it again. The speed was good and installation was very easy. Just follow the instructions. The price here is much better than the other companies like aralo or roamless etc....★

I signed up for 10 days for next to nothing. I don't know why I didn't use this service sooner. It's much cheaper than roaming. It works great in Phuket (I lived in Kata). It's easy to set up.
