Apple's online mobile payment service has been gradually expanding to new markets. Every now and then we hear Apple adding support for Apple Pay to new countries. Now, T-Mobile is looking to integrate Apple's mobile payment service so users can easily pay bills in-app and online. T-Mobile is adding support for Apple Pay to its app and its T-Mobile app.

The move will allow T-Mobile customers to pay their monthly cellular bills using Apple's mobile payment service. The option to pay via Apple Pay appeared on the carrier's website today. However, there are no official announcements of the change. The good thing is that the service can be used to get a 3 percent cash back.
