I did try this, and I’ll relay what I remember from when I tried it and then conclude with what I’m currently doing that works.
VERIZON DOESN’T WORK
Unboxed Fairphone, slotted my Verizon SIM in, and powered on. It looked to show that it recognized a network, but nothing would go through. Not 4G data, not call, not text. What seems to be the issue from that is that Verizon could have it work, but they don’t accept the device on their network. Maybe they do it for security, maybe they don’t have the the right bands support that fairphone has, or maybe they just don’t want to. So that leaves with our only other option…
REJECT VERIZION, EMBRACE LITERALLY ANYTHING ELSE
Okay maybe not anything, but it seems like most other providers work. If you want to spend the dosh, use AT&T or T-mobile, otherwise use a reseller that piggybacks off of their network. The choice there is on you, but I can personally attest to T-mobile working for me.
Hope this helps! Sorry for the delayed response.
