We have been talking a lot about eSIM (eUICC) and its advantages.

1oT is launching its eSIM (eUICC) at Mobile World Congress 2019 this February and as this launch has proven to be an educational journey for us we believe this knowledge should be shared. We would like to serialize this blog post as the third, following our previous posts, "eSIM Series #1: Clearing the Confusion around eSIM" and “eSIM Series #2: Challenges for eSIM to Overcome”.
