(Beverly Hills FL)
I purchased this phone with the understanding I could get a USB cable to connect to computer and enter the phone numbers into the computer to then transfer to the phone. But alas... if this is possible there is no indication of what kind of USB cable to get or where to plug it in... nor is there information on the program needed on the computer to accomplish this job. I do have a Mac computer which might it more difficult to find the right program. If anyone knows the answer to this please advise.
In the past I haven't had success connecting Tracfone models to PC's for syncing contacts. I did find one program from Samsung for the PC (not Mac) called Samsung Easy Studio, however it appears to be outdated, so I don't think it's really worth trying.
I don't have a T155g around to test at the moment, however if you have your contacts on another phone, you can try transferring them via Bluetooth. This works on some of the newer Tracfone models, but I don't know if it works on this one.
Sorry I can't be of more help.
