With our Mobile Solutions, you can...

Tailor your mobile plan to fit your coverage needs

Off-the-shelf mobile contracts often fall short in the areas where you need coverage most—causing dropped calls, poor signal, and unnecessary delays for your teams in the field.

FMSG builds mobile plans around your workforce and operational footprint. By working with all major UK networks, including O2, Vodafone, and EE, we match your business to the right provider and tariff for your typical usage and locations—ensuring strong signal, seamless connectivity, and reliable communication wherever work takes you.

Reduce mobile costs with flexible, usage-based tariffs

One-size-fits-all tariffs often mean paying for data or minutes you don’t use—or getting hit with overage charges when you do. That’s no way to manage business mobility.

At FMSG, we offer flexible business mobile tariffs designed around your actual needs. From SIM-only plans to shared data packages and multi-device bundles, our solutions reduce waste, improve cost control, and give you the freedom to scale without breaking your telecoms budget.

Simplify mobile management across every user and device

Managing dozens—or hundreds—of mobile lines across different users, departments, and devices can be time-consuming and prone to error.

At FMSG, we take that burden off your plate. Our mobile management services include contract oversight, number porting, device provisioning, and direct support—all through one point of contact. Whether you’re onboarding new staff or updating your fleet, we streamline your mobile operations from start to finish.

Take control of mobile usage with secure device and app management

Mobile access is essential for service delivery teams—but without clear controls, devices can quickly become a distraction or security risk in the field.

FMSG enables centralised mobile device and application management to help you stay in control. We configure each device with custom policies, restrict non-business apps, and deploy business-critical tools—giving you complete oversight of how mobiles are used, while supporting productivity and protecting your data.
