Huawei P40 and P40 Pro are the first smartphones from Huawei to be equipped with an eSIM. However, the Huawei P40 Pro+ doesn’t support eSIM.
The Huawei P40 and P40 Pro come with a single SIM (SIM + eSIM) and with dual SIM (Nano SIM 1 + NM Card or Nano SIM 2 + eSIM). – If your phone is a single-SIM device, there are still two options displayed on the screen: SIM 1 and SIM 2. The eSIM card is installed in the SIM 2 slot by default. – If your phone is a dual-SIM device and a physical SIM card is already inserted in slot 2, SIM 2 will be disabled when you add an eSIM card. Inserting or removing SIM 2 will not affect the eSIM services.
To activate your eSIM, you need a wireless service carrier which provides you an eSIM profile as well as data plans. eSIM data plans availability may vary depending on country and carrier. Ubigi is one of the carriers that support eSIM for the Huawei P40 series, in about 190 destinations, across the 5 continents.

Excellent eSIM experience in Japan!
Excellent eSIM experience in Japan!
It was super easy to purchase the eSIM before arriving in Japan, and the setup instructions were very clear and easy to follow. As soon as we landed, everything was working perfectly, and we never experienced any connectivity issues throughout our entire trip.
The internet speed was great, and the price was very reasonable for the amount of data we used. I never had to worry about limiting my internet usage or saving data at any point during the trip.
Overall, a fantastic experience! I would definitely recommend it to anyone traveling to Japan.

Switch to 2nd eSIM before flying out of USA!
I didn’t know to switch to the 2nd eSIM before turning my phone off in the US. When I turned it back on in Japan, Verizon immediately charged me $12 for a travel pass day before I switched to the Ubigi sim.
