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.

Coming to Japan alone is comfortable. No need to worry about communication. The signal is good, no cuts. Plus, you can watch many series. Calling the hotel, the signal is good. It's very good. Normally, I use roaming, so the internet runs out very quickly.

This is my second purchase. The signal is strong even in Shangri-La, and I've been able to use it without any problems. I'm going to Kunming-Korea next, so if it works as well as last time, it will be perfect. It's very convenient to be able to use it in other countries without changing the settings. I'll definitely use it again.
