customer service

Gamma Mobile is a mobile service built exclusively for the UK business market, designed to ensure you get improved coverage for voice and data. With Gamma Mobile your device will empower, not hinder your ability to conduct business. We have travel bolt-ons that are as flexible as your schedule, a fixed/mobile convergence roadmap that prepares your business for the future and you'll get a network provider with a focus on customer service excellence.


What makes Gamma Mobile different?

The key difference is that we own the core systems within the mobile network, so that makes it easier for us to manage your business mobiles, making adds and changes much more quickly.

Mobile for business

Business needs are much different to consumer - reliability is critical. Traditionally the business market has had very limited access to good value, reliable data. At Gamma we understand that the future is all about data - so we provide our business customers with access to the biggest and most reliable mobile data service in the UK, giving our customers a better overall mobile experience. As well as the best data service we offer a great range of standard and optional features including 4G as standard and business-grade voicemail.  Our voicemail that has been built with the business user in mind, with a range of great features such as extended message storage, flexible greeting options customised to particular numbers, tailored greetings based on business hours and extended greetings.  

A focus on customer service

Gamma is committed to excellence in customer service and support - it's what makes us stand out from our competitors. So with Gamma Mobile you get the same service excellence we already deliver for our other telecom services. Our UK support teams are co-located so you can always get through to the right person to handle your query, and our teams are experts in both fault resolution and provisioning.


Being contactable and able to work as normal when you are mobile is key to doing business well, so having the best business mobile network possible is paramount. With access to the biggest data network available for business in the UK, working on the move won’t be a problem. And wherever you are in the UK, Gamma Mobile’s MultiNet bolt-on enables you to do business in more places than you would with a single network. So, you won’t need multiple provider contracts and while your competitors are out of signal and their calls are going through to voicemail, you keep working - making your business more accessible.

Fixed/mobile convergence roadmap

As a fixed-line network and now with the addition of our own core systems for the mobile network, we can offer highly competitive on-net rates and are in an ideal position to make fixed/mobile convergence an affordable reality for your business.

My business issues

We also understand that you need to deliver these solutions on the back of an extensive and reliable network, which is why we've built our own to give you the best business mobile phone service we can.

We offer the best data SIM service for business in the UK - our network is built specifically for business users. We have a range of cost-effective tariffs to suit any business mobile data requirement. Whether you're using apps, browsing the internet or messaging, our data network will give you the speeds and connectivity you need. We know how important it is to stay connected which is why we won’t cut users off when they reach their threshold, instead we’ll send an alert letting them know they’re reaching their limit.

Business issue

Business issue

With Gamma Mobile there's no need to update your business cards – it’s easy to port your existing number onto the Gamma network or take out a new one.

Business issue

It’s extremely important to your customers that you are contactable for as much of the time as possible. But there are going to be times when it’s not possible to take a call and you'll need a reliable, flexible voicemail platform that's a cut above the standard residential voicemail that comes with the other networks. Our business mobile voicemail platform has been built with the business user in mind and has lots of clever features including:

Extended messages and storage – callers can leave extended voicemail messages of up to 6 minutes; any unsaved messages will be stored for 30 days. Once the message has been saved it will remain in the mailbox until the user deletes it (up to 1000 days)

Flexible greeting options with customised messages to particular numbers

Tailored greetings based on business hours - users can have one greeting for when they’re at work and another greeting for when they’re not

Extended greeting - this feature enables users to set a greeting but does not allow the caller to leave a voicemail message. It’s ideal when they’re on holiday and cannot reply to voicemails
