In November 2016, RCS Universal Profile ( Rich Communications Services ) was introduced. The technology makes it possible to send text messages into the 21st century, with many of the features being replicated by IM apps such as WhatsApp and iMessage while your phone number is being processed like normal SMS or MMS. The only thing is that your carrier must support RCS-UP in order to use the feature, but fortunately the list is growing.
Another major hurdle in the introduction of RCS Universal Profile is the "Universal Profile" part. Before Google acquired Jibe and introduced the GSMA standardization to a number of functions that should be included in all RCS-UP compliant devices and carriers, RCS had been around for four years. This resulted in fragmentation as several carriers prematurely began to roll out their own proprietary RCS versions, none of which were compatible with the others.
The Universal profile seems to fix this fragmentation, but it turns out to be a tough fight. We now have a unified, agreed set of standards to enable deployment and connectivity between different operators. However, many wireless service providers in the US (and around the world) have been slow to adopt these "Universal Profile" standards, which limits support for RCS-UP. Due to the usefulness of the technology and the slow rollout, we decided to create this list to track the progress of the rollout for your mobile operator and others.
Top US Wireless Carriers
Verizon: Currently Most Verizon phones support RCS messages through their Verizon Messages (Message +) app. However, this is and not Universal Profile. Therefore, it only works with other Verizon devices. For extended communications outside the Verizon network, the country's largest carrier has just begun to introduce support for RCS Universal Profile. But there is a catch: RCS-UP is currently available only for the Pixel 3 and 3 XL on Verizon. Verizon plans to extend Universal Profile support to all Android devices as of the first quarter of 201
- Phones: Google Pixel 3 and 3 XL (more devices arrive in Q1 2019)
T -Mobile: T-Mobile also uses its own RCS implementation through the Advanced Messaging feature. However, this is not Universal Profile. Since June 2018, T-Mobile has been supporting Universal Profile 1.0, which is slowly being transferred to the devices, with Samsung Galaxy S7 and S7 Edge in the first place. With Universal Profile 1.0, users can now transfer files up to ten times the size of standard MMS, and group chats can have up to 100 subscribers (20+) with a subject and an icon to identify the chat, and one Administrator who manages it. T-Mobile is working with Google to quickly implement newer Universal Profile standards.
- Cell Phones: Samsung Galaxy S7, S7 Edge, S8, S8, S8 Active Sprint: Sprint: Sprint was the first US airline to implement the RCS Universal Profile. It will run the latest Universal profile supported by Google's Jibe RCS Cloud. Because this is a true universal profile implementation, all Sprint Android-powered devices can use RCS messaging to communicate with Sprint customers and other vendors around the world who support this feature. From 2017, all new Android devices from Sprint will be preinstalled with Android messages as the front-end for this feature.
- Phones: All Android Devices Officially Released on Sprint
US Cellular: Similar to Sprint, US Cellular has implemented a true RCS Universal Profile. It also runs the latest Universal profile and, like Sprint, is powered by Google's Jibe RCS cloud. This means that all US Cellular Android devices can communicate inside and outside the network by using RCS messaging, provided the receiver supports this feature. For US Cellular devices, subscribers must use the preinstalled Android News app or download the app from the Play Store.

19659014] In addition to postpaid cellular operators, a number of prepaid operators support the RCS Universal Profile. Here is a list of operators who fully support the feature:
- Boost Mobile
- Freedom Mobile
- NTT DoCoMo
- Lonely talk
- Telcel América
- Tiercel Wireless 
- Total Wireless
- Virgin Mobile
AT & T: AT & T is the only major US mobile operator to offer the Universal profile yet has implemented. Instead, AT & T subscribers receive their proprietary version called AT & T Advanced Messaging. This release allows for some RCS features, but is limited to a handful of devices (Samsung Galaxy S7, S9, S9 +, and Note 9) and only works if all members are AT & T subscribers. AT & T is testing interoperability with other operators over Universal Profiles, but no timeline has yet been announced.
Google Fi: According to Nick Fox Vice President of Product Management for Google Communications, RCS should soon come to Google Fi. However, since this announcement in June 2017, we have not heard any news on a final timetable. We assume that this implementation will be fully complemented with the latest Universal profile. However, it is a bit disappointing that Google's MVNO does not. Currently this feature is not supported.
Google Voice: The service launched by Google will also support RCS messaging. Back in 2017, when the service was redesigned for the first time in years, a Google spokesman said it was working to implement the RCS Universal Profile. Similar to Google Fi, however, Google is largely silent on an actual schedule.
