Our software works with most phones and carriers out there (both inside and outside the US) with a few notable exceptions: Nextel, Boost Mobile, and Telus Mobility have disabled the ability for their users to use downloaded songs as ringtones and Metro PCS does not currently offer internet access from phones on their network. Here is a list of a few additional phones that should work, but don't beacuse the carriers have disabled the ability to use downloaded songs as ringotnes: Audiovox CDM-8915 Pantech PN-215 Sidekick II Sidekick III LG VX5200 LG VX8100 LG VX9800 (The "V") Samsung SCH-A850 As long as a phone can access the internet and can play real music ringtones chances are we've got it covered.
