Does the Sonim XP3plus work on Free Mobile?
It works, with caveats.
Works with caveatsWith 2G being switched off, calls and texts fall back to 3G, which this phone supports (2100 MHz). Free hasn't announced a 3G switch-off date. We haven't found confirmation that 4G Calling works on Free Mobile. 4G data should work (shared bands: 1, 3, 7).
It works today, but calls on the Sonim XP3plus rely on a part of Free Mobile's network with a switch-off on the way. Check the dates below before you commit for years.
We worked this out from the phone's published bands and Free Mobile's own published network facts (see How we check). Nobody has confirmed it for this exact pairing yet.
