The 10-person limit you’re hitting is a standard restriction in SMS and MMS group messaging. Default Android messaging apps like Google Messages cap SMS/MMS groups at 10 recipients, while Samsung’s app allows up to 20 (Android Authority 2025). But the 10-person limit isn’t the end of the story. You have several effective ways to reach larger groups, depending on your needs and what your recipients are using.
TL;DR
- Google Messages limits SMS/MMS groups to 10 recipients; Samsung Messages allows up to 20 (Android Authority 2025; Samsung 2026).
- RCS (Rich Communication Services) supports group chats with up to 100 participants when everyone has it enabled (Cricket Wireless 2026; AT&T 2026).
- Third-party apps like WhatsApp, Telegram, and Signal bypass carrier limits entirely.
- Specialized mass SMS apps like SA Group Text Lite can send personalized messages to 10,000+ recipients via Excel import (SA Group Text Lite 2026).
- Mixed iPhone/Android groups often force SMS/MMS fallback with lower limits, requiring third-party app solutions (Tom’s Guide Forum 2025).
Understanding the 10-Person Limit
The 10-person limit isn’t arbitrary. It’s a carrier-level constraint built into SMS and MMS group messaging protocols. AT&T’s MMS configuration file explicitly sets the recipient limit to 10 in its network settings (Replicant 2024). When you exceed this limit, your messaging app may prevent you from adding more contacts or your carrier may reject the message.
Samsung explains that the default Messaging app supports group SMS to a maximum of ten contacts, and messages exceeding the size limit automatically convert to MMS (Samsung 2026). Google Messages’ product experts confirm that the 10-person limit applies specifically to SMS/MMS group messages (Google Support 2024).
RCS: The 100-Person Solution Within Default Apps
RCS (Rich Communication Services) is the modern messaging standard replacing SMS and MMS. With RCS, you can create group chats with up to 100 participants, a significant upgrade from the 10-20 SMS/MMS limit (Cricket Wireless 2026; AT&T 2026).
The catch: everyone in the group must have RCS enabled. As O2 UK explains, RCS group chats work only when all participants have RCS messaging enabled on compatible devices (O2 UK 2025). If someone uses an iPhone without iOS 18.2 or an Android device without RCS support, the chat reverts to SMS/MMS limits.
Google Messages is the recommended app for RCS functionality. Cricket Wireless notes that they’re migrating all RCS support to Google Messages, as it offers the best RCS interoperability with more devices, including iPhones (Cricket Wireless 2026).
To use RCS group messaging: ensure everyone in your group has Google Messages installed and RCS enabled, check that all participants have compatible devices and carrier support, then create your group chat normally. If the group stays within the RCS environment, you can add up to 100 participants.
Third-Party Apps: The Most Practical Solution
For groups larger than 100 or when you need guaranteed delivery regardless of device compatibility, third-party messaging apps are the most reliable solution. These apps bypass carrier SMS limits entirely by sending messages over the internet.
WhatsApp is the most widely used option, supporting group chats with up to 1,024 participants. Its popularity means most people already have it installed, removing the friction of convincing recipients to download another app (Cashify 2026).
Telegram stands out for its massive group capacity – up to 200,000 members – making it ideal for large communities and organizations. It also supports cloud-based messaging, multi-device access, and file sharing up to 2GB (Cashify 2026).
Signal focuses on privacy and security with end-to-end encryption by default. It supports groups up to 1,000 participants and has earned a strong reputation for minimal data collection (Cashify 2026).
GroupMe is specifically designed for group texting and works across Android and iOS with SMS fallback for recipients who don’t have the app installed.
Specialized SMS Apps for Mass Messaging
If you need to send traditional SMS to large groups and want personalization, specialized apps like SA Group Text Lite and MassPing are excellent options.
SA Group Text Lite allows you to import contact lists from Excel files and send personalized messages to thousands of recipients. Features include:
- Importing group text from Excel files via USB or email
- Message personalization with tags like {firstname}, {lastname}, and {company}
- Scheduling messages for specific times
- Support for dual SIM devices
- Sending more than 10,000 personalized messages at once (SA Group Text Lite 2026)
Due to Android’s limitation of 100 SMS per hour per app, you need to install SA Group Text plug-ins to extend this limit. After downloading plug-ins, grant Send SMS permission to these plug-ins in your phone’s app manager settings.
MassPing is an open-source alternative with similar functionality. Features include Google Contacts integration, contact groups support, message personalization with placeholders like {name}, {nickname}, and {firstname}, configurable message delays (1-30s) and timeouts (5-60s) to prevent carrier blocking, and delivery tracking with background processing (MassPing 2025).
Mixed iPhone and Android Groups
Mixed groups with both iPhone and Android users present a special challenge. When you add an Android user to an iMessage group, it falls back to MMS, and carriers often block large MMS groups (Tom’s Guide Forum 2025). One forum user described this exact scenario: a group of 29 people with both iPhone and Android users where messages failed to deliver because of the 10-person MMS limit (Tom’s Guide Forum 2025).
For mixed groups, third-party messaging apps are the only practical solution. WhatsApp, Telegram, Signal, and GroupMe work across both platforms and don’t have the same carrier-imposed limits.
Contact Groups on Samsung and Other Android Phones
If you prefer using your phone’s default apps, here’s how to send a group text on Samsung phones through the Contacts app.
On Samsung Galaxy devices:
Open the Contacts app and tap the hamburger menu. Go to Groups > Create Group, type in your group name, and tap Add Member. Choose the contacts you wish to add to your group from the list. Tap Done, then tap Save. To send a message, tap the three dots menu, then tap Send Message, type your message, and hit the Send icon. You can add up to 20 recipients this way (Android Authority 2025).
On Motorola Droid devices:
Tap the “Contacts” icon on the home screen, then tap the Contacts option to open the Groups screen. Tap the “New Group” icon (showing two people), enter a group name, and tap “Save.” To add members, open the empty group and tap the green “+” button to add contacts. Tap checkboxes next to each group member, then tap Save. To send a group message, open the Messaging app, start a new message, and type the group name in the “To” field.
Frequently Asked Questions
Does group texting have a limit?
Yes. SMS/MMS group texts on most Android devices cap at 10-20 recipients. Samsung Messages allows up to 20, while Google Messages limits SMS/MMS groups to 10 (Android Authority 2025; Google Support 2024). RCS supports up to 100 participants, and third-party apps allow much larger groups.
Can RCS help me send to more than 10 people?
Yes. RCS group chats support up to 100 participants, but everyone in the group must have RCS enabled on compatible devices (Cricket Wireless 2026; AT&T 2026). If some group members don’t have RCS, the chat reverts to the lower SMS/MMS limit.
What’s the best app for sending mass SMS messages?
SA Group Text Lite and MassPing are excellent for mass SMS. SA Group Text Lite supports sending to more than 10,000 personalized recipients via Excel import (SA Group Text Lite 2026). MassPing offers Google Contacts integration and placeholders for personalized messages (MassPing 2025).
How do I send a group text to mixed iPhone and Android users?
Mixed groups often fail due to the 10-person MMS limit. Use third-party messaging apps like WhatsApp, Telegram, Signal, or GroupMe, which work across both platforms and don’t have carrier-imposed limits (Tom’s Guide Forum 2025).
What’s the difference between bulk SMS and group texting?
Bulk SMS sends individual messages to each recipient, often using specialized software or services, and is ideal for businesses and large communications. Group texting creates a true group chat where all recipients can interact and see each other’s responses, with limits set by carriers and messaging apps (Sparrow SMS 2024).
Which third-party messaging app supports the largest groups?
Telegram supports up to 200,000 members, making it ideal for large communities and organizations (Cashify 2026). WhatsApp supports up to 1,024 participants, while Signal supports up to 1,000. GroupMe supports 200 recipients with SMS fallback.
