What other kinds of phones are compatible with nextel services other then the regular nextel phones.

[Shane R]

Most Boost Mobile phones are good. You just need to make sure it takes the Nextel sim card and works on the IDEN network. Nextel is one of the only carriers that you need to use their phones on. It's because of their walkie-talkie service.Edit:If you want to use the "Nextel Services" like walkie-talkie, you cannot use a CDMA phone. There are some phones that work on both the IDEN and CDMA networks, but you can't just use any CDMA phone.
