AT&T wants you! So much so that the carrier is currently offering $650 per line when you switch from Sprint, T-Mobile, or Verizon and bring your number with you.

What’s more, if you buy one of the latest devices, you’ll get a second handset free.

Beginning today, if you switch to AT&T and buy a smartphone on AT&T Next, then port your number and trade in your old phone (worth at least $10), you’ll get $650 in credits per line.

If you choose one of AT&T’s most popular devices, such as the Galaxy S6 edge or an iPhone 6s, you’ll also get a second handset free. Together, these offers are perfect for families and small businesses with multiple lines.

“These offers are some of our best to date,” says AT&T president and CEO Glenn Lurie. “Our $650 credit is a great reward for new customers who switch to AT&T and our buy-one, get-one free is another great reward for our valued customers in the market for new smartphones.”

“There has never been a better time for new and existing AT&T customers to rack up the savings.”

The buy one get one free offer is available to new and existing customers who buy two devices from the same manufacturer. The second device must also be taken out on a new line with AT&T Next 24.

Go take advantage of these offers before they expire on March 31.
