Why choose a Three Mobile Business Contract?
Three Mobile claims over 20 years in operation and is a well-established industry leader, now servicing over 110 million customers. It was even the first 100% 3G commercial network in the UK, further advancing to 4G and now leads the charge in rolling out their 5G network.
Here are just a few benefits of choosing a Three Mobile business contract:
Award-Winning Service
You don't stay at the top by offering an average service. Over the years, Three have received an array of awards for their continued operations, coverage, and domination of data deals - even winning "Best Network for Data" between 2017-2022.
Leading Provider
Three has become one of the world's biggest network providers in just 19 years of operation. In fact, this network is responsible for up to 28% of all mobile data traffic in the UK yet retains very few service outages.
Award-Winning 5G Connectivity
Awarded the UK's "Fastest 5G Network" 5 times in a row by Ookla, based on an analysis of their Speedtest Intelligence data from H1 2021 to H1 2023. Most other major UK networks claim to have the best 5G, so proof from third-party testing is perfect!
Unlimited Data, Calls & Texts
Three Business Mobile & SIM-only deals come with unlimited data, coupled with limitless calls & texts in the UK. All of this on one of the fastest 5G networks in the country and the undisputed freedom to use your data however you wish!
No Speed or Data Caps
No more unexpected fees, employees exceeding data limits, slow connections, or dead zones. After waiving these limits, it's no surprise that the average Three customer uses 2 times MORE mobile data than the industry standard.
Great Network Coverage
Three's combined 4G and 5G networks cover 99% of the national outdoor population – resulting in some of the best coverage in the UK. This coverage remains at 99.8% for 4G connections alone, with further plans to increase 5G support in future.
Award Winning Network
Three Business sets itself apart by waiving speed limits/data caps & encouraging endless streaming, receiving “Best Network for Roaming” and “Data” awards, and many more.
Learn about some of the awards Three Mobile have won for their great service over the years:
It’s no surprise that this network saw itself voted as the “Best Network for Data” by Uswitch, not just once, but 4 times in 2017, 2018, 2021 and 2022.
This applies to both personal and Three Business accounts, making them the undisputed king of data allowances.
Alongside being awarded the best network for data, Three Business also received high praise as the “Best Network for Roaming“, also awarded during the Telecoms awards.
However, this title has since been usurped by O2, who claimed this during the latest uSwitch 2022 awards. We believe this is due to changes in EU roaming charges.
At the Mobile Industry Awards of 2019, this brand was voted the best “High Street Retailer”, alongside the “Best MVNO Partner” for wholesale.
With 311 retail stores in the UK and various wholesale agreements, their support team is always nearby…
