XP3plus 5G vs. the original XP3plus
Sonim launched the original 4G XP3plus at T-Mobile in September 2021. It runs "Sonim Proprietary OS (based on AOSP Android 11)" on a Qualcomm SM6115 chip, with 2 GB of RAM, 16 GB of storage, a removable 2300 mAh battery and a 2.8-inch inner screen. Sonim still has a page for it, linking to Verizon Business, Bell and TELUS in Canada, and distributors.
The XP3plus 5G arrived at AT&T on Aug. 20, 2025. Sonim says it "features new bands, a bigger display, and more memory": a 2.95-inch inner screen, 4 GB of RAM, 32 GB of storage, eSIM, and 5G. Sonim's carrier links for the 5G model go to AT&T, T-Mobile and Verizon Business, so it is the model US carriers sell now. This page covers the 5G model; the original's specs are in the paragraph above. [1][4][5][6]
