AT&T is offering T-Mobile customers a new deal worth hundreds of dollars just to switch carriers.
The wireless company reports it will give T-Mobile subscribers a 200-dollar credit per phone line, plus up to 250 dollars for their smartphones if they switch over to AT&T.
T-Mobile has shaken up the cell phone industry with several new programs, including its "uncarrier" strategy which got rid of contracts.
AT&T now seems to be fighting back by appealing to T-Mobile customers' wallets.
There's no date given on how long the AT&T offer will last.
