Unlocked T-Mobile iPhone 6+ on AT&T

[AndyDiamond]

Hi there - I know has probably been asked before...

I am selling my unlocked T-Mobile iPhone 6 Plus to a friend and they are on AT&T.

I am sure it will work since both phones are GSM.

I originally bought my phone outright from Apple, not T-Mobile so it wasn't locked and all that.

Should be a matter of swapping out the SIM card and restoring from their backup right?

Anyone have a heads-up?

Cheers.

Yes.
There won't be any problems using it on AT&T.
Just stick the sim inside.
