Tello, a T-Mobile MVNO, now supports RCS on iPhone after updating to the latest iOS version.RCS (Rich Communication Services) support was introduced by Apple with iOS 14, enabling richer communication between Android and iPhone users.Previously, Apple Messages did not directly support RCS for most carriers, requiring them to supply their own carrier bundle for compatibility.With the iOS 14.4 update, Google Fi became the first MVNO on T-Mobile's network to offer RCS support, and now Tello has followed suit.
