These smartphones, embedded with eSIM, come with their EID Number to facilitate the connection with the new virtual SIM card.

The most common way to find your EID, and the one applied by most smartphone companies, is to check the phone’s box, which in addition to the EID Number, you will also find about it and how to use it in case you do not have a basic notion on the subject. 

On the other hand, some smartphones have their EID numbers anchored in the internal information or configuration of the phone, so you will have to go directly into your phone settings and find it, which will be very simple.

Through these two options, you will be able to: activate your eSIM through your EID. Remember that the linking will be finished automatically once the EID is entered.

Like many smartphones nowadays, iPhones have their EID written down, stored in the box, specifically in the part where there’s information about the device, so finding it won’t be difficult, and you will be able to: activate your eSIM quickly.
