“The transition felt seamless from start to finish. We kept our mobile service and numbers exactly as they were, our team didn’t have to change how they work, and we reduced our monthly costs in the process. It genuinely felt like a straightforward upgrade rather than a switch.”
Built around the way your teams already work
Mobile+ gives you five ways to use your business phone system - depending on how your devices are set up.
Mobile+ SIM
Business calling features built directly into a physical SIM - no additional equipment required.
Mobile+ eSIM
Business calling features built into an eSIM for compatible devices - no physical SIM swap needed.
Mobile+ App
Access your business phone system through the Mobile+ app where a SIM change isn’t required.
Softphone
Make and receive calls from your laptop or computer using a simple softphone app.
Desk phone
Integrates with most desk phones supplied by BT. It should be possible for us to switch your phone without physical interaction.
For SIM and eSIM users, calls are made through your phone’s native dialler - not a separate calling app – so the experience stays familiar.
