Build Trust with
Verified Branded Messaging
-
Your brand is verified directly by UK mobile networks, giving customers confidence that they’re coming from a legitimate source and preventing fraudster impersonating your business.
Unlike over-the-top chat apps, RCS is rooted in the mobile ecosystem, where carriers are trusted to protect their customers.
-
Customers instinctively trust the verified tick, thanks to its widespread use across platforms like banks, social media, and commerce.
With RCS, that trusted symbol confirms your brand’s authenticity at a glance.
-
Your logo, colours, and business name appear front and centre, unlike SMS, where plain text can look generic or suspicious.
Branded messaging reassures customers, increases engagement, and enhances recognition over time.

RCS FAQs
-
No. RCS (Rich Communication Services) is a global messaging standard, just like SMS.
While Google currently provides the RCS platform for mobile networks (and Apple has agreed to support the standard), RCS itself is not a Google product. It’s an industry-wide standard adopted by mobile networks, handset manufacturers, and messaging vendors worldwide.
-
There isn’t one. UK mobile networks felt the term Basic undervalued RCS, so they chose to use Branded instead. It’s simply a naming choice, the technology is the same.
-
With QuickSMS, yes.
Branded RCS messages are cheaper than SMS.
Single RCS messages cost more than SMS, but they include rich features like buttons, images, and videos.
If your SMS goes beyond 160 characters (and splits into multiple parts), RCS usually works out cheaper as well, since RCS supports much longer messages in a single send.
-
An RCS agent is just the technical name for the sender of RCS messages.
As a business you can have one agent or multiple agents, depending on how you want to structure your messaging.
-
Each UK mobile network has its own process, but the goal is the same: to verify every RCS agent so that customers know they are receiving messages from genuine businesses.
This prevents spoofing and helps protect customers from fraud.
-
Brand Assure is a third-party vetting company used by BT/EE. They carry out thorough checks to confirm that businesses are legitimate. You may receive emails from them asking you to confirm that QuickSMS is authorised to send RCS messages on your behalf.
-
RBM stands for Rich Business Messaging. It’s simply another name that Google has used for business messaging over RCS. Today, the preferred term is RCS for Business.
-
Not necessarily. In the UK, Google provides the RCS platform directly, so global providers no longer have an advantage in terms of connectivity.
With QuickSMS, you get the same direct connectivity, combined with more personal service and dedicated UK support.
-
Figures are often overstated.
With QuickSMS, you can expect around 65% of your messages to be delivered over RCS today.
This is set to increase to the low 70% range once Vodafone enables RCS on iPhone, which we expect in the second half of 2025.
