Multiple lines: two numbers, one sim

[CinePhone]

Has anyone discovered if the iPhone has multiple line capabilities? I have talked with T-Mobile and can have a second separate phone number programed to my sim.

Yes, it has multiple line capability - works with my iPhone great.

Actually, this is not a phone but SIM capability.

What the iPhone DOES NOT have is displaying the actual number - so you have to remember which phone number you have turned on.

To switch between the lines, just go to Settings -> Phone -> Sim Applications.

Today I installed a Cosmote (Greece) SIM card with two numbers (2in1) and the iPhone is operating excellent.
A new menu appeared at Settings-->Phone-->SIMapplications and I activated both numbers. It takes some time and maybe more than one restart to have all set.
Everything went quite smoothly.

you can easily do this with out buying the pricy pone of having a paticular provider - i myself have ATT and i use SecondVoice | One cell phone, two numbers...

and it works fine, i have 2 numbers and it all goes to my blackjack2. works pretty good and its cheap too.

Are you unlocked? You have to be in order to use a none AT&T sim.

Sort of Google Voice type service. But GV is free... for now
