# How to Switch from SMS to RCS and What It Means for Your Business

SMS and RCS both support mobile messaging, but they create different experiences for customers and businesses. SMS remains the reliable standard; RCS expands what a message can include and how a recipient can interact with it. Feature SMS RCS Message format Plain text, usually 160 characters per segment Rich messages with images, videos, buttons, and suggested replies Connectivity Uses carrier networks and does not require mobile data or Wi-Fi Requires an active internet connection through mobile data or Wi-Fi Device support Works across nearly all mobile phones Requires compatible devices, carriers, and messaging apps Media support Limited, with MMS used for images or videos Supports higher-quality visuals and more interactive formats Engagement signals Basic delivery information May include read receipts, typing indicators, and interaction data Business branding Limited sender identification Can support verified branded sender profiles Fallback Primary channel Falls back to SMS or MMS when RCS is unavailable The practical takeaway is simple: SMS helps your business reach the widest possible audience, and RCS helps you create a more engaging experience for those customers who can receive it.

For most Android users, the process for enabling RCS happens inside Google Messages or the device’s default messaging app. The exact wording may vary depending on the phone model, operating system version, and carrier, but it generally follows a similar process:
### Step 1: Open Your Messaging App
Start by opening Google Messages . Many modern Android devices use Google Messages as the default app, and it offers one of the most consistent RCS experiences across supported carriers. If your device uses another messaging app, look for a similar area related to RCS chats or chat features. The app must support RCS for the setting to appear.
### Step 2: Access Settings
Tap your profile picture, initials, or the three-dot menu in the upper-right corner. From there, open Messages settings . Look for an option labeled RCS chats . On some devices, this may appear as Chat features . This is where you can check status, manage read receipts, adjust typing indicators, and review resend settings.
### Step 3: Enable RCS Chats
Toggle RCS chats to on . You may be asked to verify your phone number during setup. Once active, your phone will use RCS when you message another person who also has RCS enabled. If the recipient does not have RCS support, the message will be sent as SMS or MMS instead. To confirm the change, send a message to an RCS-enabled contact. Read receipts, typing indicators, or higher-quality media sharing can indicate that the conversation is using RCS.

On iPhone, RCS requires iOS 18 or later, which includes the current iOS 26, and carrier support. Once both are available, enabling RCS is done through the iPhone’s settings.
### Step 1: Confirm iOS 18 or Later Is Installed
Open Settings , then tap General , then About . Check the Software Version field . If your iPhone is running an older iOS version, go to Settings , then General , then Software Update . Follow the prompts to install the latest available version.
### Step 2: Verify Carrier Support
RCS on iPhone also depends on your wireless carrier. You can check carrier details by going to Settings , then General , then About . Look for carrier information that indicates support for voice, SMS, and RCS. If you do not see RCS listed or are unsure whether it is available on your plan, contact your carrier directly.
### Step 3: Enable RCS Messaging
Once your software and carrier support are confirmed, open Settings and go to Messages . Find RCS Messaging and switch it on . After that, your iPhone can use RCS when messaging Android users who also have RCS enabled. These conversations still appear in green bubbles because blue bubbles remain specific to iMessage conversations between Apple devices.

RCS may not activate immediately for every user. In most cases, the issue comes from carrier availability, app compatibility, internet access, or the recipient’s setup. Try these steps first: - Check carrier support:RCS availability depends on the carrier, so confirm that your mobile provider supports RCS on your device and plan.
- Confirm your internet connection:RCS requires Wi-Fi or mobile data. A weak signal or offline device can prevent messages from sending through RCS.
- Restart your phone: A restart can resolve minor setup delays after you turn on the RCS setting.
- Update your messaging app: Older app versions may not support current RCS features, even if your device and carrier are compatible.
- Verify your phone number: Some devices require number verification before RCS becomes active.
- Test another contact: If RCS works with one person but not another, the issue may be on the recipient’s side.
- Look for the message label: If a conversation shows a standard text message label rather than an RCS label, the message is likely using SMS or MMS fallback.
This fallback helps ensure messages can still be delivered even when RCS is not available.

As more customers switch from SMS to RCS, businesses gain more opportunities to send richer, more action-oriented messages. That can be especially useful for campaigns where visuals, trust signals, and quick responses affect performance. SMS still provides the base layer. It offers broad reach, high visibility, and familiar customer behavior. RCS simply builds on that foundation with a more flexible format.
### More Customers Reachable with Rich Messaging
Every customer who enables RCS becomes reachable through a more dynamic native messaging experience. For businesses, that can mean verified branding, product visuals, buttons, suggested replies, and clearer paths to action. Apple’s adoption of RCS also expands the potential audience. Businesses can plan for rich messaging across both Android and iPhone customers while preserving SMS as a reliable fallback. Review your existing contact list. Identify audience segments where richer messages could add value, such as high-intent leads, loyalty members, appointment-based customers, or event registrants.
### Stronger Engagement and Better Analytics
RCS gives businesses more ways to understand customer behavior. Read receipts and interaction tracking can provide more context than basic SMS delivery reporting. That additional tracking data can help you compare campaign types. For example, a retailer might test a product image and button against a standard SMS promotion, or a service business might compare a plain appointment reminder against an RCS message with a confirmation action. [Research shows](/report/2025-consumer-texting-report) that texting already plays a larger role in customer communication: Fifty-two percent of consumers text businesses more often, and 57% expect a response from businesses within 15 minutes. RCS can work with that behavior by making replies and next steps easier to manage.
### A Hybrid SMS and RCS Strategy
Most businesses should use RCS alongside SMS rather than treating it as a full replacement. A hybrid strategy sends RCS when the recipient can receive it and defaults back to SMS when they cannot. This approach protects reach while allowing richer experiences for customers with compatible devices and carriers. It also gives your team room to test RCS on high-value campaigns before expanding it more broadly. It’s also worth noting that [SMS marketing](/resources/sms-marketing) best practices related to compliance, opt-in consent, and message frequency apply to both SMS and RCS. As such, organizations that already have strong SMS programs will likely have an easier time extending those practices to RCS. [EZ Texting Contact Management](/features/contact-management) supports hybrid strategies by keeping subscriber data organized and usable. With contact uploads, platform syncing, custom fields, and segmented groups, businesses can better understand which audiences should receive richer RCS-style messages when available and which should receive SMS fallback. That structure also helps keep messaging more relevant, permission-based, and manageable as subscriber lists grow.

Knowing how to switch from SMS to RCS gives you clearer insight into the customer experience, but your business also needs a clear operating plan . RCS gives you more creative options, yet the message still needs to be useful, compliant, and easy to act on. - Get clear opt-in consent: RCS business messaging still reaches customers on personal mobile devices, so TCPA consent, opt-out handling, and message transparency remain essential.
- Keep one main call to action:RCS can include buttons, visuals, and suggested replies, but each message should still guide the recipient toward one clear next step.
- Use media to clarify the message:Product images, event graphics, maps, and branded cards should support the goal of the text rather than distract from it.
- Segment your audience:Send richer messages to the groups most likely to benefit from them, such as recent buyers, active subscribers, appointment holders, or local event audiences.
- Automate timely follow-up: Automation can be used to trigger messages based on purchases, signups, appointment dates, abandoned carts, or registration activity to reduce manual work.
- Track performance after each send: Review delivery, reads, replies, clicks, conversions, and opt-outs so you can refine your approach.
- Preserve SMS fallback: Some customers will not have RCS available, and some messages still work best as short, direct SMS updates.
The goal is to make richer messaging more useful, not more complicated.

### Will switching to RCS use more mobile data than SMS?
Yes. RCS uses Wi-Fi or mobile data instead of the carrier’s SMS network. Plain text messages use very little data, but rich content like high-resolution images and videos can use more, especially for users on limited data plans.
### Can RCS be enabled on older Android phones?
Sometimes. RCS support depends on the device, Android version, messaging app, and carrier. Most modern Android phones support RCS through Google Messages, but older devices or unsupported carriers may not offer the feature.
### Does switching to RCS affect existing SMS conversations?
No. Enabling RCS does not delete or change existing SMS threads. Your phone simply uses RCS for future messages when the recipient also supports it and continues using SMS when RCS is unavailable.
### Is RCS free to use for consumers?
Usually, yes. RCS typically does not add per-message charges because it uses Wi-Fi or mobile data instead of the traditional SMS network. For most users, it is covered by their existing data plan.
### What happens to group chats when some members have RCS and others do not?
Mixed group chats may fall back to SMS or MMS, depending on the devices, carriers, and messaging apps involved. Full RCS group chat features generally require all participants to have RCS enabled and supported.
### Do businesses need to do anything differently when customers switch from SMS to RCS?
Not manually. A compliant messaging platform like EZ Texting can route messages to the appropriate format, sending RCS where supported and using SMS fallback when it is not available.
