I just bought a TracFone Motorola V170 online but really wanted to use the SIM in another unlocked phone. Reason I bought the V170 because someone on one forum said it was impossible to use another manufacturer's unlocked SIM in a TracFone. Now tonight I read a message on the Cingular side where a person broke his Cingular, bought a TracFone at WalMart (I think) put it in the TracFone and it worked. There wasn’t any other detailed info like calling customer service, etc. Is there a TracFone expert on here that can tell me what’s the real deal? I’ll probably be happy with the V170 (it’s backordered) but really want to use a Cingular Razr that someone is giving me that doesn’t have a SIM card. Thanks for any kind of heads-up informa...

Tracfone's SIMs are different than other GSM SIMs, how exactly I don't know*, but I tried that - I got a Tracfone Nokia 1100, unlocked it, and the phone worked with my AT&T wireless SIM, but the firmware shut it off after the prepaid minutes were used, even though I had a differen SIM in there!
Likewise the SIM itself I tried in several unlocked phones, it always said "Invalid SIM" - the only phone it worked with was the 1100.
Dollars to doughnuts it won't work**.
* - Actually, I do: Tracfone is far too powerful for any mere mortal phone!
you go to hell with your cingular razr! the v170 represents the highest of all cellular achievements! these include: 250 contact storage (on SIM only), 16 chord ringtones (who needs 64?), and, get ready for this one, a calculator! doesn't that just blow your mind? you can do your math while out about in your car, without carrying another device! why would you want something else?!
