Mobile Phone Networks: a simple guide
Mobile Phone Networks: a simple guide
If you live in an area where mobile phone coverage isn’t great, you may be frustrated with your mobile network provider. So, it’s always good to look around at the other providers, both big and small, to check coverage in your area and tariffs to suit your budget.
What’s a mobile network operator? (MNO)
These are the companies that provide your mobile phone services. They provide the network that enables you to send and receive calls, texts and access the internet. In the UK there are four main network operators.
Who are the biggest UK mobile networks?
The UK’s four largest mobile networks include EE, O2, Three and Vodafone. These phone networks supply the most customers and have the widest coverage in the country. They also support many of the smaller mobile virtual network operators, by providing them with access to their wider network. This is often referred to as piggybacking.
What is piggybacking?
‘Piggybacking’ is a term used to describe the way that mobile virtual network operators (MVNOs) cover their customers. Smaller mobile networks don’t typically have their own mobile networks, so they instead rent access to the networks supplied by the larger providers.
What’s a mobile virtual network operator? (MVNO)
MVNOs are smaller operators that rent infrastructure, buy space from or piggyback one of the four main network providers.
This means that if you subscribe to one of these MVNOs, then you’ll get the same coverage as the main operator.
It’s often worth knowing who the MVNO is piggybacking services from. If you know you’ve a bad signal or data speeds from one provider, then there’s no point signing up with an MVNO who shares their network.
Which mobile providers are powered by other mobile networks?
Which mobile providers power GiffGaff, Sky & Tesco Mobile?
Giffgaff, Sky and Tesco are all large mobile plan providers, however, none of them operate their own networks. These three are all examples of mobile virtual network operators (MVNOs) who rent the services of even larger networks. GiffGaff, Sky and Tesco Mobile are all powered by O2.
|Main provider||MVNO renting space|
Which mobile phone network has the best coverage?
The mobile phone networks have created a much more level playing field when it comes to 4G coverage across the UK. All of the major mobile networks have achieved almost complete coverage, with EE and Three only slightly ahead.
|Mobile network||4G Coverage (% of UK population)|
Of course, with 5G starting to roll out in 2019, the next coverage race has begun. EE were the first to launch 5G in the UK, and have made a strong start in getting towns and cities connected with the fastest speeds.

Which is the best mobile phone network for customer service?
Customer service is pretty even across the board – which is great news for all mobile phone users. The big four providers appear to provide a consistent level of customer service and Tesco Mobile came out best for the MVNO provider group.
Which is the best phone network?
There are too many factors to crown an overall best mobile network. Your phone model, location, network coverage, data plan and customer service are just some of the things that make up a good phone network, with each provider performing better or worse in each area.
Ofcom runs reports on the main aspects of mobile providers’ services and for 2018 EE performed well for coverage, data speeds and what extras it offers its customers directly. However, all four of the major phone networks (EE, O2, Three and Vodafone) scored a minimum of 92% for general customer satisfaction.
Which mobile networks provide 5G?
The launch of 5G began in the middle of 2019, with more mobile networks joining the race in 2020. Here are the mobile networks currently offering 5G in select locations:
- Tesco Mobile
Are there any disadvantages to using a smaller mobile phone network?
Not really. In terms of coverage and data speeds, you’ll get the same service as customers who buy their phone services direct from the big four networks, so there shouldn’t be too much to grumble about.
The main area where you might be at a disadvantage when using a smaller provider is that you won’t qualify for any of the main network’s freebies and rewards – only those directly contracted to the big four will get these perks.
How to choose a mobile provider
Now you know more about mobile phone networks, you might want to switch provider.
To compare deals, have an idea of what you are looking for from a mobile provider price plan – how many calls you make, texts you send or how much data you would likely use – all to make sure that the best-fit price plan can be found for you.
Some things to consider when comparing mobile providers include:
- Cost – think about how much data, call minutes and texts you use a month. Data is often a big part of mobile cost, and, while it’s great to have unlimited data, if you’re only using 2GB a month, you don’t need to pay the extra for it.
- Contract length – do you want to be tied into a long-term contract, or do you appreciate the freedom to switch when you need to? Common contract types range from rolling monthly, to two-year plans. You normally find slightly better deals for longer contracts, but if flexibility is important to you, it can be worth the higher price.
- Coverage – the big four mobile phone networks (EE, O2, Three and Vodafone) each have approx. 99% national coverage. If you’re looking at a smaller provider, consider a mobile virtual network operator (MVNO), who uses the network of a larger provider.
- Additional benefits and extras – some mobile providers will offer benefits such as data rollover, free access to media streaming or even priority access to events.
