Crazy Deal Alert! Get Unlimited Premium Wireless from Mint Mobile and the New Samsung Galaxy S25 for $30/Month

This milestone offer celebrates a major evolution in messaging for Mint customers, as Rich Communication Services (RCS) — the next-gen messaging standard — can now work for Mint customers regardless of which phone they have. That means anyone can “like” messages, send high-resolution videos and participate in group chats, regardless of which device they are using.

Check out what Mint Mobile’s very own Ryan Reynolds had to say about the news

“When we brought this idea to our finance team, they thought we were joking,” said Andrew Fried, CMO at Mint Mobile. “Unlimited data and the incredible Samsung Galaxy S25 for just $30/month seemed impossible, but here we are. And now, because of RCS, you can fully embrace those green text bubbles in the group chat. So this is the perfect time to get one of the most advanced Android devices in the market at an unbeatable price on the nation’s largest 5G network.”

What Is RCS — and Why It Matters

RCS allows all devices to experience the latest messaging capabilities irrespective of what operating system they are on. That includes:

  • Typing indicators and read receipts
  • High-res image and video sharing
  • Smarter, real-time group chats
  • End-to-end encryption (on supported platforms)

For Mint Mobile users, this means no more switching apps or dealing with incompatible texting experiences — just smooth, modern messaging that works across the board.

So that’s it. An unbeatable deal. A better experience. And it’s one more reason Mint Mobile isn’t just the smarter choice — it’s an obvious one. Not to mention, customers get to enjoy even more incredible benefits like free roaming in Canada, free mobile hotspot, Wi-Fi calling and so much more, making Mint the ultimate no-brainer wireless solution.
