Why is 3G Shutting Down in the UK?

First introduced in the early 2000s, the older 3G network infrastructure simply isn’t designed to handle the demands of today’s data-intensive mobile services and consumer needs.

Here are the main reasons why UK carriers are shutting down their 3G networks:

  1. To increase capacity for new, high-bandwidth applications such as virtual reality, live video streaming, and other multimedia content.
  2. Provide a better customer experience by improving coverage and signal strength on newer, more advanced networks.
  3. Improve the battery life of mobile devices by reducing the amount of signal interference from legacy networks.
  4. Accommodate the massive growth of connected devices and machine-to-machine communication on emerging Internet of Things (IoT) applications.
  5. Remain in compliance with new regulations and standards implemented across the industry that mandate backward compatibility.
  6. Reduce maintenance requirements, decrease operating costs and encourage more sustainable and environmentally responsible business practices in the long run.
  7. Reduce strain on existing infrastructure and ensure that new 4G and 5G networks continue to deliver high-quality services to customers.
  8. Free up valuable spectrum for upcoming 5G networks that are better equipped to handle the significantly increased data traffic expected in the coming years.
  9. Improve security with modern 4G / 5G networks and make it easier to protect sensitive data transmitted by users and set advanced security measures.

All of these benefits work to provide even better performance, lower latency, and greater network capacity across the country – enabling carriers to offer more innovative mobile services.

Why 2024?

Over the last decade, EE, Vodafone, Three, and O2 have all been investing heavily in new 4G and 5G networks to offer faster speeds and more reliable connections across the UK. These carriers feel it’s time for that investment to pay off.

With these new 4G/5G networks, users will enjoy seamless connectivity and better performance, enabling them to stay online, entertained and productive, no matter where they are.

What to do before the 3G Switch-Off:

Users who still require 3G will either need to switch to newer devices or face network disruptions in the future. It’s important to upgrade your device or tariff before your network deadline.

Here’s what you can do to prepare for the 3G Switch-Off:

  1. Upgrade to a compatible device that supports either 4G or 5G – shop our business phone contracts & work tablets for all of the latest models.
  2. Check network coverage of 4G or 5G networks in your area to ensure the use of your mobile devices without disruption.
  3. Contact your mobile service provider to check your existing tariff includes 4G/5G coverage and upgrade as necessary.
  4. Back up data to avoid any loss of important information when upgrading.
  5. Plan ahead and allow sufficient time to make necessary changes to devices or tariffs to avoid any service disruptions.

Tips for Business Users:

From small businesses with a couple of SIM cards to large corporations with hundreds of employee handsets, the 3G Switch-Off is set to impact companies all across the UK.

To mitigate any negative impact, take an inventory of:

  • Employee devices
  • Mobile SIM applications
  • 3G data-connected devices

Before the date outlined by your network, your business must:

  • Upgrade outdated devices to newer models (all mobiles, tablets, SIMs, and tariffs will need to be 4G/5G ready
  • Replace all active 3G Business SIM plans

What’s next?

Despite the widespread impact of the 3G Switch-Off, EE and other carriers are optimistic that the move will ultimately benefit consumers by improving network performance and reliability. 

They are also encouraging customers to take advantage of upcoming upgrade offers/deals that make it easier and more affordable to transition to newer technologies.

To support this trend, Vodafone has launched several tracking and monitoring solutions, including VOXI which targets IoT services such as remote machine control.

Interestingly, a union under a Vodafone and Three merger has been announced, anticipated by 2024. This will result in a new largest UK mobile network operator.


While the transition away from 3G may cause some short-term interruptions for users, it’s ultimately for the greater good. We’re sad to see it go, but in honesty, when was the last time you actually relied on it?

Vodafone, Three, and EE all urge customers to upgrade their devices to more modern models that support 4G or 5G. If you’re set on sticking with 3G, moving over to O2 is your best bet.

3G Switch-Off UK FAQs

3G and 4G refer to different generations of mobile network technology. “Third generation” was introduced in the early 2000s and provided faster data transfer speeds than its predecessor, 2G.

Mobile users could finally access the internet, make video calls, and download and upload files at a tolerable speed. Later, 4G (or fourth generation) arrived in 2009 and offers far faster data transfers; capable of providing download speeds of up to 100 mbp/s.

While 3G is still in use in some parts of the world, many countries have migrated to 4G and are now beginning to introduce 5G, the next generation with speeds in the gigabits!

Yes – 3G will be turned off all over the UK. The process of shutting down the third-generation network has already started, and it is expected to be completed by the start of 2024. Major mobile network operators EE, Vodafone, and Three, have all announced plans to switch off these networks.

While most operators are preparing to shut down their networks, O2 is expected to continue operating its network for the foreseeable future. However, customers are encouraged to upgrade to 4G or 5G compatible devices for better network performance.

This technology has been used for more than a decade and can no longer keep up with the increasing demand for faster, more reliable mobile internet connectivity.

As a result, mobile network providers are phasing out 3G to make way for more advanced and faster technology, such as 4G and 5G.

The switch to newer, faster networks will also allow mobile network providers to free up valuable radio spectrum frequencies that can be used for other purposes or to boost 4G and 5G capacity.

If you have not upgraded before the deadline, services may be disrupted and you may experience issues making/receiving calls and text messages, or accessing the internet via mobile data.

If you continue to use an incompatible device, you may be able to connect to the network via a 2G signal, which is far slower and less reliable than 4G, or 5G. However, this service may not be available in all areas and may eventually be phased out as well.

To avoid disruption to your mobile services, it is essential to upgrade to a 4G or 5G compatible device before your carrier’s network shut-off deadline. Check with your carrier about its plans and deadlines for shutting down 3G services and consider upgrading to compatible devices on time.

The UK’s 3G switch-off will affect Mobile Virtual Network Operators (MVNOs) in different ways.

MVNOs are mobile phone service providers that do not own their network infrastructure but instead lease it from other network operators. They offer services to customers using the networks of the operators they partner with.

With the upcoming switch-off, MVNOs that resell services provided by EE, Vodafone, or Three must ensure that their services are compatible with 4G or 5G. This would likely result in MVNOs upgrading their technology or leasing new infrastructure to be compatible with the latest networks.

For MVNOs that partner with O2, where 3G will continue to operate, the impact of the switch-off will be less significant. As O2 has decided to continue operating its network, partnered MVNOs will not need to make the same level of immediate changes as those that operate on other networks.

Various devices support 4G and 5G connectivity, including smartphones, tablets, and modems.
Here are 10 popular devices that support 4G:

1. Apple iPad Pro 11″ (2022)

2. Samsung Galaxy Tab S8

3. Alcatel 1S (2021)

4. Amazon Fire HD 10 (2019)

5. Microsoft Surface Pro 7

6. Lenovo Yoga Smart Tab

7. Google Pixel Slate

8. Asus Chromebook Flip C434

9. Sony Xperia XZ3

10. Nokia 7 Plus

And here are 10 devices that support 5G:

1. Samsung Galaxy Tab S7 FE

2. Apple iPad (Pro Range)

3. Google Pixel 6 Pro

4. Apple iPhone 14

5. Samsung Galaxy S23

6. Nokia 8.3 5G

7. LG Velvet 5G

8. Xiaomi Mi 10T Pro 5G

9. OnePlus 8 Pro

10. Sony Xperia 1 II

Please note that this is not an exhaustive list, many more devices support 4G/5G connectivity. Compatibility may vary based on the mobile network and country. Check with your device manufacturer or mobile network provider to confirm if a specific device is compatible with 4G or 5G in your area.
