THE EXACT date that millions of phones will stop working as the UK’s biggest network provider set to turn off their 3G access in a huge shake-up.
Some customers might be left with no data at all to access the internet or message friends on WhatsApp when they’re away from home.

The network provider details
All of the UK’s biggest mobile networks have been slowly turning off access to 3G and that means devices that can’t connect to newer 4G and 5G signals could lose access to data and all-important services.
O2 alerted its 23 million customers of the changes earlier this year.
But now three more locations set to wave goodbye to the old network in just a few days.
O2 is the last of the big networks to make the change, as part of an objective agreed with the Government in 2021.
After more than 20 years, the company is stripping out 3G to make way for more faster 4G and 5G services.
The shake-up will also impact Tesco Mobile, GiffGaff and Sky Mobile, which rely on O2’s network technology.
When it will happen

The next areas will be Norwich, Telford and Guildford[/caption]
For most people, the demise of 3G shouldn’t be a problem but for a small number of users it will result in a data blackout.
Because some older handsets aren’t able to handle 4G or 5G.
They’ll still be able to make calls and send texts, but without 3G they won’t be able to get online when out and about.
However, they can technically still go online when using Wi-Fi.
The next areas where O2’s 3G will be switched off on July 16 are:
- Norwich
- Telford
- Guildford
It’s already ended in the city of Durham.
Torquay will follow on August 4 and the whole of the UK should then lose access by the end of the year.
How to save on your mobile phone bill
NOT happy with your current mobile phone deal?
If you’re outside the minimum term of your contract then you won’t need to pay a cancellation fee – and you might be able to find a cheaper deal elsewhere.
But don’t just switch contracts because the price is cheaper than what you’re currently paying.
Take a look at how many minutes and texts, as well as how much data you’re using, to find out which deal is best for you.
For example, if you’re a heavy internet user it’s worth finding a deal that accommodates this so you don’t end up spending extra on bundles or add-ons each month.
Also note that if you’re still in your contract period, you might be charged an exit fee.
Ready to look elsewhere? Pay-as-you-go deals are better for people who don’t regularly use their phone, while monthly contracts usually work out cheaper for those who do.
It’s worth using comparison websites, such as MoneySupermarket and uSwitch.com, to compare tariffs and phone prices.
Billmonitor also matches buyers to the best pay-monthly deal based on their previous three months of bills.
It only works if you’re a customer of EE, O2, Three, Vodafone or Tesco Mobile and you’ll need to log in with your online account details.
There’s also MobilePhoneChecker, which has a bill monitoring feature that recommends a tariff based on your monthly usage.
If you’re happy with your provider then it might be worth using your research to haggle a better deal.
Customer support

O2 will be focussing on their more reliable connectivity for customers[/caption]
The closure is part of O2’s longer-term plans to deliver faster and more reliable 4G and 5G connectivity for customers.
Vodafone, Three and EE have already completed their 3G switch-off with customers no longer able to access this slower signal.
Virgin Media O2 said: “3G services in those areas will be switched off in the coming weeks, and those who currently don’t have a 4G or 5G device must upgrade to a compatible handset in order to retain access to mobile data services.
“While we know that the vast majority of our customers already have a 4G or 5G device and will not have to take any action, our priority is to provide support to those who need it,” said Jeanie York, Virgin Media O2’s Chief Technology Officer, said
“That is why we are reaching out directly to customers who do not have a 4G or 5G handset, and calling those we know are vulnerable, to provide information about their next steps.
“It is important these customers upgrade their handsets in order to continue using mobile data after 3G is switched off.”
