Can a phone be unlocked for both GSM and CDMA?
The short answer is no. If you have an older device that is only equipped with GSM technology, it will never work well on CDMA networks like Verizon or Sprint, even if it’s an unlocked phone. If you have a phone that’s CDMA only then it won’t work well on GSM networks, like AT and T-Mobile.
What can you do with old CDMA phones?

Is it possible to switch from CDMA to GSM?
It’s possible to switch from CDMA to GSM. Bell and Telus in Canada have done it to get access to the wider variety of off-the-shelf GSM phones.
