    Rock solid and performs very well

    This thing is ready for the next war! Talk about rugged. Very impressed. Solid as a rock. Quite hefty, though. It has nice touches like the light flashes when it is called, along with the usual ringer. It can be made to ring quite loudly. A missed call will have the light blink every couple of seconds, too. Some specs I read elsewhere said it did not have video but this one has photos and video. It also has multiple LAN connections for 2.4 and 5.0. The only slight downside is that the PTT button, when accidentally pushed (in the case of T-Mobile), will ask you if you want to sign up for that service. There probably is a way to turn that off but I haven't delved into all the features yet. It's very solid. I use this as a backup, emergency phone. No doubt it could survive ...

    Works great as a Zello Work radio even without a SIM using wifi. Audio quality seems to be pretty good from the couple transmissions I've heard so far

    Bought this Sonim XP3 Plus flip phone for my elderly mom. The battery life is amazing, several days. But the phone is large and heavy. T-Mobile locked, I'm running on Tello. Only complaint is that a stock T-Mobile app gives a pop-up about wanting to register twice everyday; cannot turn it off. Only requires two button clicks to dismiss, so I guess it's fine.
