  • Kind of. GSM (which all but Verizon and formerly Sprint used) let most any phone on the network. CDMA let carriers pick and choose compatible devices. In the early 2010s when Verizon was attempting to buy more spectrum for its 4G network, Google put themselves as a potential buyer, but they wanted the FCC to set a rule for the spectrum that said any phone compatible had to be allowed onto the network. Verizon won that auction and since then Verizon’s been way more open on what they allow.

    And with Sprint being purchased by T-Mobile, it would make more sense at this point to have a phone certified for AT&T and T-Mobile and Verizon would just have to let it on the network. These days, a phone being “certified” is Moore just a carrier making the statement of “we’ve tested the phone and we do know it works on the network.“ it doesn’t mean an uncertified phone will never work, it just means that this one should work by all metrics they’re able to tell.

    My guess is a lot of that rule was created to cut down on the “is this a good server?” Questions. Which I could see becoming a problem.

    Maybe a rule specifically calling that out and a weekly “Hardware guidance” post that people can comment and ask those kinds of questions?




  • You cannot just buy any SFP module and have it work. Most ISPs deploy a “special” (at least compared to normal point to point fiber links) that lets them serve multiple customers out of one port in their office. This is called a Passive Optical Network and requires specialized modules on both ends. There are ways to make a specific SFP work as an ONT and by cloning certain identifiers from the ONT to make the ISP think their box is still there.

    This is a lot of effort and from my research, could stop working randomly in some cases.
