Your Razr is equipped with an eSIM (dematerialized SIM) only and has no traditional SIM card slot! This means that you need to have an eSIM provider to be able to use your smartphone to make calls, send SMS, surf the Internet or use your favorite mobile apps.
For calls and SMS, you must therefore contact your usual home-based operator to replace your physical SIM card with an eSIM to be able to use your phone.
For data-only plans while traveling abroad for instance, eSIM allows you to have another line and another eSIM profile provided by another operator such as Ubigi. Ubigi provides a large range of affordable worldwide eSIM data plans, up to 90% cheaper than roaming fees with your home-based operator, in 190 destinations in the world.
Activating your Ubigi eSIM data-only service is easy. Just make sure you have a Wi-Fi data connection on the device and follow the eSIM installation steps below to get started.
Explore Ubigi eSIM data plans for seamless connectivity worldwide!
Install once, stay globally connected for life with a single eSIM, compatible with all eSIM-enabled devices : iOS Phone, iPad OS, Android, and Windows 10 and 11.

Great service with great documentation!
Great service with great documentation!
Initially, the data connection was not working but thanks to Ubigi's extensive documentation I was able to narrow it down to a missing APN configuration and fixed it quickly on my own.
Since I have had no problem and the 5G connectivity works well.

It was very easy to top up or purchase…
It was very easy to top up or purchase a new plan while overseas, and the status updates were useful and relevant. Reception in Tokyo was very good. However, when I travelled to Hakuba in Nagano Prefecture, the reception was quite poor. It would be great if coverage outside the main cities could be improved.

Overall really great
Once I understood how to get everything set up it was great, I only had a handful of times where the reception wasn't amazing.
