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.

Highly recommended for Turkey
I went to Turkey for a few days (Istanbul to be exact). I bought the 10GB eSim from Ubigi for one week. I never had an issue of connectivity or something else, the speed was very good. It's a pity I didn't have much time to spend the whole 10 GB package I bought.
Highly recommended. Just make sure your phone supports the eSim technology.

Sometimes get no internet connection on dual eSIMs. Have to disable the alternative one to make Ubigi work. But other then that it works

Simple & easy to use
Had been reading lots of info about travelling & esims, and Ubigi was really straightforward, easy to use and had great deals. So reassuring to be abroad and not have to worry about any data costs while navigating & getting online. Will def use again in the future.

Great Experience
I’ve used a few eSim providers when travelling overseas and Ubigi is my favourite to date. Very intuitive to set you and no drop outs.
