In a move that enhances convenience for multi-device users, Serbian mobile operator mts has launched a new service called “One for All.” The innovative feature allows customers to use their existing mobile number across up to three different devices, offering greater flexibility and seamless connectivity.

This means mts users can now make and receive calls, send texts, and access mobile services using a single number—whether they’re on their phone, tablet, smartwatch, or even a secondary handset.

A Simple Idea That Solves a Modern Problem

Many users today juggle more than one connected device. Business travelers, remote workers, or tech-savvy users often carry a phone and tablet—or a smartwatch they want to stay connected. Until now, this usually meant managing multiple SIM cards or forwarding calls between devices.

mts’s “One for All” service simplifies all that. It allows a single mobile number to function across up to three different SIMs or eSIM-enabled devices, creating a more unified digital experience without the need for call forwarding, multiple accounts, or switching between phones.

What’s Included

Though mts hasn’t released full technical details or pricing as of this writing, the service is expected to support:

• Voice calls and SMS on all devices simultaneously
• Single billing across all linked devices
• Easy setup and management, likely through the mts app or customer service

It’s also likely the feature supports both physical SIMs and eSIMs, in line with current European operator trends. That would make it ideal for pairing smartphones with tablets, wearables, or second phones used for travel or business.

mts Leads the Pack

As the dominant player in Serbia’s mobile market—holding over 44% market share—mts continues to set the pace in terms of innovation and customer-centric services. Competitors like Yettel and A1 Serbia offer strong coverage and similar pricing, but mts’s move to launch a true multi-SIM, single-number service gives it an edge, especially as device ecosystems become more integrated.

In fact, services like this have become increasingly popular in global markets, especially as eSIM technology becomes more common. With eSIM-compatible phones and tablets on the rise, being able to manage a single number across all your connected devices isn’t just a convenience—it’s becoming an expectation.

A Strategic Move for Today’s Traveler

For frequent travelers, business professionals, and digital nomads, “One for All” has strong appeal. Imagine being on the go with a tablet and smartwatch, while your primary phone is charging or lost in a bag—you can still receive calls and texts without missing a beat.

This is also an efficient solution for those using dual phones—one for work, one for personal life—who want the simplicity of a single number and bill.

What’s Next?

While mts has made the announcement public, it hasn’t yet released full instructions on how to activate the “One for All” service or what it will cost. If the rollout follows similar offerings in other European markets, we can expect a small monthly fee per additional device, bundled packages, or even introductory free trials for existing subscribers.

The real value, however, lies in the seamless user experience. No more missed calls. No more duplicate contacts. Just one number, working for you—on whatever device you’re holding.

Final Thoughts

With “One for All,” mts is not just launching a new feature—it’s responding to how people live and work today. By turning one mobile number into a multi-device passport, the company is creating a smarter, more connected future for its customers.

As more people adopt multiple smart devices and as eSIMs continue to change the telecom landscape, services like this will likely become the new norm. For now, mts is one step ahead—and users are the real winners.
