Selling my Sonim phone, this is probably one of the most robust phones available, waterproof down to 2 meters too. I think youtube have clips of these phones being driven over etc!
I have had it about 2 years. It comes with spare battery but I have never used it because the battery life in these phones is about 10 days on stand by!
Its open to any network.
If you have any question, please feel free to get in touch.
