doesn't have to be a current one that Verizon offers even a older phone that has the new technology looking at an extravert 2 it's not on this list .No longer supported LG devices | Verizon Wireless
or xpression 2 which states its gsm technology.
There are plenty of places to buy new old stock phones I really despise buying from Verizon as well I just like their network I never have an issue with service where ever I go that's the only reason I keep them as my provider.
The only basic phones that will work are the ones in the link I posted. You can take my word on that or not but it's the truth.
the xpression 2 does not have LTE neither does the extravert 2. It has to have LTE especially band 13 and support Verizon VoLTE. No non-Verizon basic phones do that. And the only Verizon phones that do are the only one still being sold
