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.

Fast connection
As soon as we landed in Haneda, I turned it on and it worked perfectly fine. The connection was fast too.

Great connection from the moment I arrived
I bought an internet-only plan before leaving Brazil because I was worried about arriving in Japan without internet, especially for Google Maps, translations, and staying in touch with people.
Ubigi has worked great for me. The internet is fast and reliable, and having a connection as soon as I arrived made everything so much easier.
I’d definitely use Ubigi again and highly recommend it to anyone traveling abroad!
