UK Business Mobile Phone Contracts

Right at home with delivering low-cost mobile contracts.

Amidst rising operational costs for businesses, CoByEx stands as a trusted partner of UK-based businesses as well as organisations with remote teams operating globally to ensure seamless and reliable connectivity. Our tailored solutions have significantly reduced domestic and international roaming by 20-50% for our customers.

Flexibility is at the heart of what we do. Never be locked into a contract again with 30-day rolling SIM-only contracts with no penalty charges so you can scale or adapt your tariff as your needs change.

We don’t have a set tariff list, meaning we can offer a choice or multi-network combination of the major UK networks (O2, EE, Three and Vodafone) to secure the best coverage at the best price, and all on the same invoice for easy invoicing.

At CoByEx, we’re all about transparency and with us, you’ll never get a bill shock with customisable data alerts and spend caps. As part of our data-driven approach, we offer quarterly usage audits and use our data insights to guarantee you are always getting the best value for your money on your tariff.

How It Works

Step 1 - Consultation call

We’ll book in an initial consultation call to discuss your requirements. We understand that no two businesses are the same so we’ll find out how you use your devices, how often you travel and to what locations.

Step 2 – Data audit and proposal

We’ll conduct a free analysis of your last 3-6 months of bills so we can see where we can save you money on domestic mobile use and international roaming charges. We’ll then send you a proposal showing what tariff will best service your needs.

Step 3 – Sign Up

Happy with your proposal? The Customer Support team will onboard you and sign you up to your tariff. They’ll also be on hand throughout your relationship with us to check you’re getting the most out of your plan.

Cost Effective Contracts for UK-Only Operations

If you don’t make international calls or travel abroad, there are still significant savings to be made. We tailor your plan to match real usage - offering shared data pools, individual bundles, or unlimited options across multiple networks. And with 30-day rolling contracts, you can scale up or down as your team changes—without being locked in or overpaying.

Why Pay More For Your Mobile Business Contract?

Many businesses across the UK are unknowingly paying too much for their UK mobile contracts. With so many tariffs, networks, usage patterns, and long contract terms, it’s easy to get stuck with a one-size-fits-all solution.
At CoByEx, we take a different approach—using real data and in-depth analysis to build mobile plans tailored to your business needs. No guesswork. Just the right plan at the right price, for the duration of your contract with us.
On average, we save our customers between 20% - 50% on UK and global mobile tariff charges!

FAQs

How do you create a custom mobile plan for my business?

Whatever your business needs, our Customer Service team is on-hand to deliver you a plan that is bespoke to you. We’ll have a consultation with you to understand your data requirements. We’ll conduct an analysis of your last six months of billing to see where we can save you money and then propose a tariff to save you money and reduce your contract length.

Can I switch networks or adjust my plan if my needs change?

Yes, you can switch networks or adjust your plan when you need changes. We don’t have a standard tariff list, so you can switch between networks that have the best connectivity depending on your location. Don’t worry about monitoring your usage, we’ll produce quarterly reports on your usage to make sure you’re still on the best plan for you.

What roaming options do you offer for international travel?

If you travel internationally, we offer global coverage for voice and data connectivity without excessive roaming charges. We cover 230 countries around the world so you can stay connected wherever you are. Our bespoke international plans are designed to offer flexible and cost-effective solutions on a single bill.

How does your support differ from network providers?

At CoByEx, we’re customer-first and product second. We pride ourselves on our values of transparency, truth and trust and we’ll never sell you a service you don’t need. We’re more than just transactional. We have dedicated account managers on-hand to offer support and to review your usage on a quarterly basis for you. We simplify roaming so you can enjoy travelling stress-free.

CoByEx have been a huge support to our small business with no problem too hard to solve. The service they provide is surprisingly good value & they deliver it with an exceptional level of customer care. Looking forward to many more years working with them.

We have been with CoByEx for many years and now consider them not only long-standing service providers but also trusted industry friends. Their team consistently goes above and beyond to deliver exceptional service, and their pricing remains unmatched. It's rare to find a provider that combines reliability, expertise, and genuine care for their clients the way CoByEx does.

Our business has been a customer of CoByEx for several years. The greatest complement I can pay them is the fact that we don’t speak to them very often, because the service they provide our team works flawlessly. It just works. If we do need ever support, we have real human beings as contacts, who actually achieve the result we need, such as adding a new line at extremely short notice. Highly recommend.
