RCS Messaging on O2

RCS (Rich Communication Services) Messaging enhances the messages you send from your normal Device Messages app, with things you can’t do when sending standard SMS or MMS messages. Here are examples of some of the new features:

• Send longer texts - you're not limited to 160 characters

• Typing indicators – see when your contact is typing in a conversation

• Read receipts – know when your message has been read

• Large group chats – create group chats with up to 100 participants who also have RCS Messaging enabled

• High-quality media sharing – share pictures and videos in high quality

• RCS Messaging over WiFi– send messages even when you don't have a mobile network connection

• Transfer large files – send larger attachments

• Sound Clips

• Location Sharing

No, RCS Messaging enhances what you can do in your normal device messages app, regardless of device type. Any two people who have RCS Messaging enabled on their devices can exchange RCS messages, even if they’re using different messages apps to do it. RCS Messages work on all Android devices supporting Android 5.0 or above and all iPhones supporting iOS 18.2 or above. If your Messages app is compatible, you can use it as normal – just make sure you have RCS features enabled in settings.

RCS Messaging is available on any Android device running Android 5.0 or above and all iPhones supporting iOS 18.2 or above.

You can get RCS Messaging by downloading Google Messages from the Play Store.

If you want to disable RCS Messaging on your device, just follow these steps:

1. Tap Settings

2. Search RCS

3. Disable RCS by tapping the toggle. You can re-enable from here at any time.

It won’t cost you anything to use RCS Messaging but, unlike SMS and MMS messages, RCS Messaging uses your data connection. So, if you use RCS Messaging when you’re not connected to WiFi, the data will come out of your allowance, if you have one, or you’ll be charged for the data you use.

Follow the instructions below to see if RCS Messaging is enabled on your device or for a particular conversation.

Your messaging app will send messages via RCS Messaging whenever it can, you’ll see next to the “send” button, it will show as “SMS” or “RCS”.

And you can also check whether or not a message was sent via RCS Messaging, after you’ve sent it. If data or WiFi is not available to enable RCS Messages, it will revert to SMS/MMS and charges may be incurred.

1. Open the Settings menu

2. Search RCS

3. The RCS toggle in settings will either disable or enable RCS Messaging.  We recommend you leave this switched on.

Long press a sent message and then select Info from the top menu to see whether it was sent as an RCS message or an SMS.

Once RCS is enabled on your device, you can chat with any other person who has RCS enabled on their device, across multiple networks across the world.

Before you send a message, your Messages app will check whether your contact can receive RCS Messaging. If they can’t, your message will be sent as a standard SMS or MMS, unless you disable this in the Messages settings.

Open a conversation with another user who also has RCS features. If the box that you type in says ‘RCS’, then RCS Messages are enabled on your device. If the edit box says, ‘Text message’, your phone is not able to send RCS Messaging to that user.

If you get a new SIM, but keep your phone number, you’ll still be able to use RCS Messaging automatically.

If there is no data connection for your phone, for example if you’ve turned data off or if you’re in an area with low data connectivity, you won’t be able to use RCS Messaging. The Messages app will automatically switch to using SMS/MMS as long as you have a network connection and you haven’t disabled this in the Messages settings.

You can send RCS Messaging when your device is connected to a WiFi network, however you may experience issues if you're not in an area with mobile network coverage. Even when it’s connected to WiFi, your device still needs to use its network connection every now and again to keep your service up and running. If the Messages app is unable to make this connection, RCS Messaging may be unavailable, even if you’re on WiFi.

Yes, you can block someone so that you no longer receive any calls or messages from them.

First open the conversation with the contact you want to block, open the settings menu and you’ll see a ‘block’ option.

You can archive the conversation by swiping to the left or right, or delete it by long pressing the conversation and selecting Delete at the top of the screen.

If an RCS Messaging message can't be delivered and you don't get a delivery confirmation, you are given the option to resend your RCS Message as an SMS or MMS if you want to.
