The switch off of 2G & 3G networks and the role of Ofcom

The final switch off for 2G & 3G networks is due to happen in 2033; although the actual implementation is up to the mobile network operators so it could be earlier in some areas, Vodafone have in fact started with 3G being turned off throughout 2023.

How will the switch off affect you?

Well, this could potentially affect everyone in some way.  There may be some people with legacy handsets without capability to connect to 4G/5G; there may be geographical pockets without any network coverage at all.   However, it is not just about mobile calls. There is still a lot of IoT technology that is reliant on 2G & 3G networks, smart meters are just one example of how we currently use 2G.

So understandably Ofcom is keen to prevent any potential harm to any consumer.  Whilst it has no formal role (i.e. they have no powers of enforcement), in order to protect consumers from being caught out and to enable Ofcom to track progress and keep the switch-off running smoothly, they have announced some key expectations on how mobile network operators should handle it.

Here are four key expectations:

Minimising coverage impact:

This is self-explanatory; some providers have already made progress on this one.  For example, we recently read that EE, Three and Vodafone have committed to ensuring that they offer a broadly equivalent level of coverage after the 3G and subsequent 2G switch-off. With areas currently reliant on 3G/2G being upgraded to 4G ahead of switch-off.

Contractual information about the switch-off of services:

Mobile providers should explain in their contract information and summary when the service being purchased will no longer function on the 3G and/or 2G networks (where known) and that the customer will need a 4G capable handset after that date.

Communicating with and providing support to customers:

Where customers need to replace or update their handsets, Ofcom expects networks to raise general awareness and provide end-users with a minimum of three to six months’ notice with information about the steps they need to take to make changes.  Vulnerable customers, particularly those struggling financially, will need to be given additional support – this might include offering discounts on replacement handsets.

Other services that rely on mobile networks:

As mentioned, the switch-off will also impact a range of other IoT devices, including Telecare alarms and payment terminals. These services will require a longer notice period. Many of them use “roaming SIMs” and do not have a direct customer relationship with UK mobile providers. Ofcom expects all mobile networks to identify these services, share knowledge and raise awareness so that relevant suppliers have sufficient time to update their devices and consumers do not lose access to vital services.

The Next Steps

Ofcom has confirmed that it is already working closely with mobile providers and other affected stakeholders to keep them informed of any issues that may arise with the 2G/3G switch-off. They will also provide clarity on what to expect during this process. They will also continue to work closely with the Government, Consumer groups and other relevant stakeholders to help raise awareness of the upcoming switch-offs.
