T-Mobile Simple Choice subscribers will soon be able to make and receive phone calls, SMS and access 4G LTE Web without paying any roaming charges in Mexico and Canada. The carrier's new initiative, dubbed “Mobile Without Borders,” is slated to begin from July 15.

The new move from T-Mobile will allow customers to travel in North American countries and avail the same service as the carrier provides in the U.S. The free roaming services are exclusive to U.S. citizens, available for free for both postpaid and prepaid customers with Simple Choice plan, reports Mac Rumors.

T-Mobile subscribers who are on other promotional or older plans can get Mobile Without Borders free roaming services by paying a fee of $10. Some have said the carrier started this new service only to attract more subscribers from its rivals.

CNET claims that in the previous month T-Mobile launched a new plan that allowed users to upgrade to up to three smartphones a year. For instance, if a user gets a new smartphone with an 18-month lease plan, he will not have to pay any down payment, just a certain amount each month.

After using the handset for some time, the user can swap it and avail another device without paying an extra fee. However, the user will have to get a new 18-month lease plan and make monthly payments for the remaining period. T-Mobile is allowing users to get premium smartphones like the Galaxy S6, the Galaxy S6 Edge, the iPhone 6 and the iPhone 6 Plus through this new plan.

The carrier has added over 1 million new customers consistently for each of the past four quarters. Among them, 760,000 are postpaid subscribers, whereas 178,000 are prepaid customers.
