DON’T use in China
If you travel to China, DONT USE this service. I bought an Asia unlimited plan for 15 days, payed US$ 43. My trip started in China, I went to Hong Kong, and on my way back to China, the e-SIM stopped working. I was without internet in Shanghai and couldn't even leave the airport because nothing works with the Wi-Fi in Chinese airports. After an hour I managed to leave the airport, but the e-sim still didn't work. I had to buy one from another operator, and when I spoke to AirAlo support in the middle of my vacation, the representative only asked for information and screenshots, even though it was clear that it wasn't working. I didn't need a solution, as I had already spent more money with another operator. The representative did nothing, just give me a measly five-dollar credit. Therefore, if you go to Asia, don't use AirAlo.
