A Business-Grade Mobile Network Built for Business Calling

Mobile+ runs on a dedicated business-grade mobile service — built on the UK’s largest mobile network.

The Problem With Standard Mobile & VoIP

Why most mobile business calling falls short

Standard mobile contracts give your team a number, but not a business phone system. App-based VoIP tools add features, but often depend on WiFi or mobile data to make calls.

That creates problems for mobile-first teams:
‍

- Call quality varies depending on signal, WiFi or data conditions
- Users may fall back to personal mobile numbers
- Customers receive an inconsistent calling experience
- Business calls can be missed, delayed or unmanaged
- IT teams have limited visibility and control
‍
Mobile+ is different. It brings business calling into the mobile voice network, combining the reliability of native mobile calls with the control of a cloud phone system.

Business calling at a network level

Mobile+ provides a dedicated business-grade mobile service built on the UK’s largest mobile network.

Business calls are handled as true mobile voice — not VoIP. That means:

True mobile voice quality

Calls run over the mobile voice network, not internet VoIP.

UC features built into mobile calls

Transfer, hold, conference and record calls on mobile.

Business identity at network level

Present your business number on every outbound call.

No reliance on Wi-Fi or data calling

SIM and eSIM calls work through mobile signal.

This is network-level business calling
not app-based VoIP.

Business mobile coverage that goes further

Mobile+ doesn’t stop at the UK. It supports global roaming across a wide range of destinations, helping your team stay connected with a consistent business calling experience when travelling.

Roam like home in selected countries

Roam away in selected destinations for up to 90 days in any 365-day period

Standard roaming in many additional countries via 24-hour Day Passes

So whether your team is working locally or internationally, Mobile+ helps keep business calls connected.
