Multimedia Capabilities
RCS comes with a range of multimedia features that enhance the messaging experience compared to traditional SMS and MMS. These include sending high-quality images and videos, voice and audio messages, the ability to share files, real-time location and status, animated stickers and emojis, as well as the creation of group chats.
SMS: Limitations in Sending Text and Links
SMS has some limitations compared to RCS technology when it comes to sending text and links, making it less flexible.
SMS allows sending text messages of up to 160 characters. If this limit is exceeded, the message is split into parts of 153 characters, creating a concatenated SMS, which results in additional charges depending on the text length.
On the other hand, links can be included in SMS messages, but without preview capabilities. This means images and call-to-action buttons cannot be displayed.
RCS: Support for Images, Videos, and Files
RCS vs SMS allows sending and receiving high-quality images, videos, and files.
One of RCS's key advantages is image sharing, as it allows sending images in their original resolution with broad format compatibility, such as JPEG and PNG. Additionally, users can preview images without needing to download them.
Besides images, RCS also supports high-quality video sharing without requiring downloads, compatible with formats such as MP4 and MOV.
Lastly, this new system allows sending files and documents in widely used formats such as PDF, DOCX, and PPT. These files can be quickly downloaded without requiring external apps for access.
Interactive RCS Features Like Quick Reply Buttons and Shopping Carts
RCS SMS introduces not only multimedia but also interactive features, such as quick reply buttons and shopping carts, which are valuable tools for business campaigns and communications.
Quick reply buttons allow users to respond with a single click, eliminating the need to type. This feature is highly beneficial for customer service and appointment confirmations.
Meanwhile, shopping carts allow users to add products or browse interactive catalogs without typing. With a single button, customers can add items to their cart and even select payment gateways directly, without switching pages.
The table below summarizes the key differences between the two messaging options:
SMS | RCS | |
---|---|---|
Connection | Does not require internet | Requires Wi-Fi or mobile data |
Character limit | 160 characters | No limit |
Sending images and videos | No (except low-quality MMS) | Yes, in high quality |
Read receipts | No | Yes, double check |
Group chats | No | Yes |
Message reactions | No | Yes |
Encryption | No | Depends on carrier and device |
Compatibility | All mobile phones | Only on compatible devices and carriers |
Cost | May have a cost depending on carrier | Free with internet |

Common Use Cases for RCS and SMS
Both RCS and SMS are essential business communication tools, but each has its own strengths and applications. Below are some common use cases to maximize SMS marketing campaigns.
Interactive Promotional Campaigns
Choosing RCS SMS as a marketing and advertising tool allows businesses to reach their audience with a wide range of possibilities. Compared to SMS, RCS offers more interactive features that enhance the user experience.
It also enables automated order tracking with a simple link click and allows customers to take advantage of personalized promotions.
Enhanced Customer Support
By incorporating interactive buttons and links, RCS provides a much richer and improved customer experience. For instance, users can confirm, cancel, or reschedule appointments without making a call or engaging in a live chat.
For customer service, RCS enables AI-powered automated responses and allows solutions to be shared via images or videos.
All of this makes customer interactions faster and more efficient, addressing inquiries instantly.
Urgent Notifications and Alerts
SMS remains the most reliable resource for urgent situations or when users lack internet access, as it enables the delivery of emergency alerts, security codes, and time-sensitive communications.
Ultimately, RCS is a more complete solution when interactivity, multimedia, and higher engagement are required.
However, bulk SMS remains the best option for sending urgent communications, alerts, and verification codes.
