This linked blog post answered one of my questions that made me hesitant to buy the device. I couldn’t see any information that I could understand that would indicate what wireless service provider’s I could use. I was worried that I might need to use Verizon. Today I have a Fi account and it straddles the T-Mobile and Sprint networks. I was guessing that any factory-unlocked phone would work at any carrier, but I have had places say that they couldn’t allow a particular device.
I never had the knowledge of prepaid data SIM’s before. That sounds interesting. My plan was to port over my old cell number from a MagicJack VoIP to the Librem 5. Seems I can do that or maybe some magic forwarding thing to have the Librem 5 pass calls through that VoIP number.
