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.

The network card provided by this adapter in Osaka demonstrated a very stable and fast signal, and was easy to install. It is also very reasonably priced.

These eSIM cards are a great idea. No need to bother with buying physical ones anymore. Have you tried buying and registering a SIM card in the Philippines? Our friends tried, and it took a terribly long time. Overall, if your phone supports eSIM, I highly recommend buying it here. It's less hassle and cheaper.
