Frequently asked

Business mobile, your questions answered

What networks do you offer for business mobile?
As a Mobile Virtual Network Operator (MVNO) we have direct access to all the major UK networks, so you can have O2, Vodafone, EE and Three across your handsets, mixed and matched to suit each user, all under one agreement and a single invoice.
What is an MVNO and why does it matter?
A Mobile Virtual Network Operator provides mobile services using the major networks' coverage, but manages its own billing and customer support. For you, that means flexibility and fast, UK-based support, without waiting on a slow third-party provider.
Can you help control our mobile costs and roaming?
Yes. Our team monitors your data usage daily to spot unusual or high usage early, catching roaming spikes before they hit your bill. We also audit your existing tariffs to find savings.
Do you offer SIM-only, or handsets too?
Both. Keep your existing devices with a competitive SIM-only agreement, or take the latest iPhone, Samsung Galaxy and tablets on flexible contracts, preconfigured and ready for work.
Can you secure and manage the devices, not just supply them?
Yes. Alongside connectivity we can set up Mobile Device Management (MDM) so staff can securely access email, calendars and company documents on the move, with your data protected.
