Three Mobile are known as ‘The Network Built for the Internet’. During the last few years, they have gone from strength to strength as a network both in terms of service and infrastructure. You can check online to see if you are in a 4G coverage area in the UK, and while you are abroad it is highly likely that you will fall within one of the 30+ countries currently covered by the network for free roaming (certain tariffs only). Alternatively, you can call 3 Customer Services and for an in-depth review of services available in your area.

About 3 Mobile

Three Mobile’s network was primarily made for the internet and they actually cover around 40% of the UK’s mobile data traffic. They were the first mobile network to offer all-you-can-eat and unlimited minutes, texts and data bundles for their contracts.

They also launched the ‘feel at home’ offer whereby customers can use data within their allowance when abroad and on holiday. This offer is still available and is a core to their sales, giving flexibility for their customers. They offer 4G connection on their mobiles with no extra charges or commitments.

They are dedicated to running their business responsibly and offer customers really fair prices and a great customer service.

Three is a telecommunications and internet service provider operating in the UK. They are a subsidiary of Hutchison Whampoa. The company was formed in March 2003 as the first video mobile network in the UK. The company offers customers 3G and 4G service through their own network infrastructure. In 2004, Three announced that it was the first network to reach its regulatory requirements of 80% of the population coverage across the UK.

The first 3 Mobile stores opened the same day the company launched, with two shops in Oxford Street and Kensington High Street and the Birmingham Mailbox. The company soon grew and their products and handsets were being sold online and by other phone providers. By 2006, the company had opened 95 high street shops from O2 and The Link, expanding the brand.

In 2010, 3 Mobile was voted the best network for mobile broadband in a YouGov survey for the second year in a row. 2014 saw the introduction of the inTouch app which enables Three customers to route calls or texts via Wi-Fi networks when the 3 signal is unavailable. Three customers are able to utilise the Vodafone network when in the London Underground and cannot get any signal. In 2015, Three announced their interest in acquiring the O2 network, subject to regulatory approval.

Contact Three for Outstanding Customer Service

If you have any issues or questions then it would be good to pass them over to Three Mobile customer service advisors who will be able to help you get to the bottom of any issues. Contact them today on 0843 515 9066 and someone will be happy to help.


If you are looking for a contract with Three Mobile then just browse through their option of the latest handsets in-store or online. Once you have picked the phone you like then it is time to look for the deal you want for your network. You need to think about the data and messages you want and how many minutes you will need a month. Most Three Mobile contracts already have unlimited minutes and texts but you can decide the amount of data you want on your phone.

Mobile Phone Upgrades

To upgrade your phone contract you need to check what date your contract finishes. You can do this by going in-store or logging into My Three app online or on your phone. From there you can see all of your allowances and data and the date you will be able to upgrade. If you are ready for an upgrade then take a look at the latest handsets either online or in-store. Once you have decided on your new handset then head in-store and speak to an advisor about upgrading your contract. If you have any issues or questions you can speak to an advisor on 0843 515 9066.

Three Rescue

You can take out Three Rescue to cover your phone or tablet if it were to be damaged, stolen or broken. This is Three’s own brand of insurance and according to reviews is well worth the money. The service is great and it is always a good idea to get your phone insured after purchasing it. If you do have to use 3 Rescue then you may have to pay an excess of around £80, but Three Rescue will cover the rest.
