iPhone Carrier Unlocking and Functional Testing

[nerdyiphonen00b]

Hey guys,

Recently purchased 30+ iPhones at an electronics repair store that's going out of business. These phones are all gently used/like new and very little to no information (original carrier, country of origin, ect) was provided about these devices. Models range from iPhone 5c through iPhone 7.

Looking to accomplish 3 things for each phone:
1) Make sure they're all 100% functional (no charging, touch screen, connectivity issues)
2) Carrier unlock them. I know some phones have hardware that only allows them to work on a CDMA or GSM network. Need to make sure if they're carrier unlocked they'll work on all 4 of the major carrier networks.
3) Confirm none of these phones are blacklisted or unable to activate.

Any idea of the best way to do this?

A very risky investment. These phones are probably security locked.

Each of them were data wiped and not icloud locked

If any of them are carrier locked you may have to pay the carrier to have them unlocked, if they’ll do it for a non customer.

And, if there are any outstanding contract fees, you would have to pay those.
