It sounds that way according to their wikipedia entry:

"TracFone service is limited to TracFone-branded handsets (all TracFone 
handsets are pre-programmed by the manufacturer; therefore, the handset is 
locked including its latest GSM models). Other GSM handsets will not accept 
TracFone SIM cards, even if unlocked. Additionally, on most handsets, some 
features like USB and Bluetooth have been modified by the manufacturer to 
prevent direct transfer of user files."

This probably means they do something nonstandard talking to the SIM, which is 
handled by the closed GSM chipset firmware. If Osmocombb ever becomes a 
replacement for the closed firmware you might be able to work out what's 
different and add support for it.
