EU mobile SIM with your company’s fixed number

Mixvoip introduces a new generation of EU SIM cards that bring your fixed business number directly to your mobile phone without any app or smartphone required.

One number for your business identity

With our fixed mobile convergence (FMC) SIM, every call you make shows your company’s fixed line number. When customers call back, the call is routed to your office phone system, where colleagues can pick up and handle it professionally.
This feature is essential for teams on the move like technicians, healthcare workers, or field staff, who need to stay connected while keeping their professional and private lives separate. It’s also one of the easiest ways to support the right to disconnect. When you’re off duty, on holiday, or sick leave, calls are automatically managed by your company’s system instead of reaching your mobile.

EU coverage with Luxembourg and international numbers

The Mixvoip FMC SIM works across the EU and supports both Luxembourg and international fixed line numbers. Choose between two simple plans:
  • Pay-as-you-use: Starting at € 1.90 per SIM, €1.30 per GB EU-wide. Perfect for mobile staff, caregivers, or teams that need connectivity without large data consumption.
  • Data package: includes 25 GB for those who need more regular use.

Beyond a basic mobile SIM card: rich features for every use case

Compatible with Microsoft Teams, our cloud PBX and our SIP trunks

The SIMs integrate naturally with SIP Trunk’s, Microsoft Teams and our Cloud PBX solutions, offering a unified communication experience wherever you are.

Replace your DECT system

If your company still relies on DECT handsets or costly wireless infrastructure, this is your chance to modernize. Our FMC SIMs let you call colleagues by simply dialing their internal extension, just like from your desk phone without antennas, cabling, or setup costs.

National roaming

You can even switch mobile networks. Just choose the one that gives you the best signal.

Works everywhere, even on a Nokia 3310

No apps, no configuration, no smartphone dependency. The service runs directly on the SIM card, making it compatible with any device — even the classic phones you might still have in your drawer.

Fleet data connectivity

You can also use these SIMs in tablets or routers for affordable fleet data connectivity, which is ideal for work devices that don’t waste data on social media.
