T-Mobile will let you use your phone in Canada and Mexico without a roaming fee

They can also call Canadian and Mexican numbers from the US without incurring any fees.

The program kicks off on July 15.

That plan allowed you to use data, but it was limited to a slower 2G connection.

The new move gives customer access to the fastest possible connection in both countries.

T-Mobile partnered with two carriers in Mexico and six carriers in Canada for full roaming coverage.

Customers will have the same amount of high-speed data they have under their usual plan.

An AT&T spokeswoman wasn’t immediately available to comment on T-Mobile’s new plan.

The free calls to Mexico and Canada represent a boon to T-Mobile customers.

“It’s a huge impact for our customers,” Legere said.

For some T-Mobile customers, there are a few wrinkles.

Existing customers will have to check a box in their plan to add the feature.

The carrier is working on making it accessible, a spokesman said.
