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 29% of all mobile data traffic in the UK yet retains very few service outages. ​

Great 5G Connectivity

Awarded the UK's "Fastest 5G Network" in 2022 by Ookla. This verdict is based on an analysis of their Speedtest Intelligence data for Q1-Q2 of 2022. Most other major UK networks claim to have the best 5G, so proof from third-party testing is perfect!

Unlimited Data, Calls & Texts

3 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 data caps or speed limits.

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 3.5 times MORE mobile data than the industry standard.

Leading Network Coverage

Three's combined 3G and 4G 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:

Best Network for Data, 2017-2022 - uSwitch Mobile Awards

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.

Best Network for Roaming, 2020 - uSwitch Mobile Awards

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.

Best High Street Retailer, 2019 - Mobile Industry Awards

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…

Three Business FAQs

Thinking of switching over with a 3 Business mobile deal but still have doubts?
Read all FAQs, or find all of the most frequently asked questions for this network below:

Is Three Business your Best Choice?

Choosing a Three Business deal is a fool-proof plan for SMEs and large corporations alike and a great way to save money.


As one of the UK's biggest mobile networks, they also provide business broadband and operate internationally, proving themselves one of the largest in the world.


If you often exceed data limits or have an employee who likes to stream movies a little too much, a 3 contract is the one for you. Otherwise, if you're after additional corporate functionality, Vodafone may be your best bet.

Can I get a Three Business SIM Only contract?

YES – most of our best-value company SIM only contracts are from Three Business and come with several benefits, including those listed above.


Cut out any confusion - call us or contact our team today and we’ll find the best options for you.

Is 3 a good network for the UK?

YES – this brand is considered one of the best mobile network providers for personal and business users alike. We highly recommend choosing between Three, O2, EE, and Vodafone.

Is it Three or 3 Network?

Technically, both are correct. The full word is used throughout their website and whenever referring to their company name.


On the other hand, the “3” number is mainly used throughout their logo, imagery, and branding.

Does 3 Mobile own O2?

YES - founded by BT Ireland and operating under the name "Telefónica Ireland", Three Mobile purchased the O2 brand in March 2015 for £10.25B.


Since then, there have been rumours of BT entering talks of buying back the O2 brand, but nothing is confirmed yet.

What MVNOs are they responsible for?

An MVNO stands for a Mobile Virtual Network Operator, which refers to a service provider that does not own the network infrastructure.


There are currently three MVNOs under this network provider: SMARTY, iD Mobile and FreedomPop.
