Overview

Building on the success of the Sonim XP3plus, the new XP3plus 5G flip phone makes a good thing even better. Built to the same military-class durability standards (MIL-STD-810H, IP68) as its predecessor, the XP3plus 5G incorporates plenty of new features, including faster 5G* connectivity speeds, added bands for more bandwidth and stronger security, and a more useful larger display. Everything you need, nothing you don’t, the XP3plus 5G brings more to the table, for less.

great phone, do consider
I don't understand any of the negative reviews for this phone. It is an awesome flip phone, though is tough and a bit heavy. you can check msgs without opening, as well as change the sound/silent options. you can also answer without opening....i hardly open it and use it well! am about to order my second as backup since it's 5G and will last a while in case I drop/damage mine. large but fits in a back pocket just fine.

Bad Phone
No one could get it to work right--they tried everything-even a factory restart. It's flawed. And I got charged a $55 restocking fee. You must make a killin' on restocking it.
