SIM Unlock the Audiovox SMT5600

HTC Voyager (C500, AudioVOX SMT5600) unlock in under 5 min

Florin, the head honcho over at has finally found a fix for the problem he ran into when SIM unlocking Audiovox SMT5600 Smartphones. Whereas before, the unlock would turn your phone into a paperweight, the unlock process now fully supports the SMT5600.

If you want to use an SMT5600 on a carrier other than AT&T Wireless (and who wouldn’t?), you can purchase an unlock from Florin, and then use the phone on any GSM network in the world (since it’s quad band).

Being able to unlock the SMT5600 for use on T-Mobile was one of my critical criteria, and I’m happy to see that this barrier has been lifted. Thanks, Florin!

    Hi, you mentioned above that the SMT5600 is a quad-band phone. Is this correct? All the info I have gathered about the SMT5600 is that it is 850/1800/1900mhz and missing the 900mhz. Perhaps unlocking the SMT5600 will enable 900Mhz?

    the date is charged based on your carrier,some carriers charge by the minute,some charge totally separate from the voice minutes.
