What Is the 2G Switch Off, and Why Does It Matter?
The UK’s mobile networks are retiring their oldest technology. The government and network operators agreed back in 2021 that 2G and 3G would be switched off across Great Britain by 2033 at the latest, freeing up spectrum for 4G and 5G. The 3G switch off is already well underway, and the 2G switch off is the next, bigger job.
Most people won’t notice a thing. Smartphones fall back to 4G or 5G without a second thought. The 2G switch off matters far more for anyone still relying on an older basic phone, or a device that quietly depends on a 2G signal without you ever thinking about it, like a telecare pendant alarm.
When Is the 2G Switch Off Actually Happening on Your Network?
Later than you might expect, and staggered by provider. EE plans to begin its 2G switch off from May 2029, O2 from summer 2029, and Vodafone during 2030. Three doesn’t run its own 2G network, so it isn’t affected in the same way. Nothing changes for any of these networks this year.
That gap matters. It gives households years, not months, to check whether any device in the house genuinely needs 2G, and to sort it out at a sensible pace rather than in a last minute scramble. Our guide to the 3G switch off covers the network that’s actually being retired right now, if that’s the more urgent one for you. Confusing the two is an easy mistake, and it’s worth knowing which one actually applies to your household this year.
Why Does the 2G Switch Off Matter So Much for Vulnerable Users?
Because some of the devices that quietly rely on 2G are the ones people depend on most. Telecare pendants, personal alarms and some lone worker devices have historically used 2G to reach a monitoring centre in an emergency. Many have already been upgraded to multi network SIMs that hop onto whichever signal is strongest, but not every device in every home has been.
Ofcom has a real enforcement record here, and it’s worth knowing about even though it involves a different switchover. In late 2025, Ofcom fined Virgin Media £23.8 million for disconnecting telecare customers during its landline digital switchover, after failing to properly identify which customers relied on their line for a personal alarm. It’s a stark example of what happens when a provider gets vulnerable customer protection wrong, and exactly the kind of failure Ofcom is determined not to see repeated as the 2G switch off approaches.
What Are Providers Legally Required to Do Before the 2G Switch Off?
Identify vulnerable customers and treat them fairly, under Ofcom’s General Condition C5. That means providers are expected to have clear policies for spotting customers who may be at risk, whether from a switchover or anything else, and to give them tailored support rather than a generic letter.
For the 2G switch off specifically, Ofcom has already published coverage data and written to local authorities and the telecare sector to raise awareness well ahead of any switch off date. If you or a relative uses a telecare device, it’s worth asking the provider directly whether it already uses a multi network SIM, rather than waiting for a letter that may or may not arrive at a useful time.
Telecare pendants aren’t the only devices quietly running on 2G. Some older burglar alarms, lift emergency phones and payment terminals used the same network, and businesses relying on any of these have just as much reason to check now as individual households do. The 2G switch off timeline gives everyone years of notice, but only if the check actually happens rather than getting filed away for later.
2G Switch Off Timeline, Checked August 2026
| Network | 2G switch off starts |
|---|---|
| EE | From May 2029 |
| O2 | From summer 2029 |
| Vodafone | During 2030 |
| Three | No 2G network to switch off |
| Government deadline for full 2G/3G retirement | By 2033 at the latest |

Key takeaways
- The 2G switch off starts from 2029 depending on your network, with full retirement by 2033 at the latest.
- Most smartphones are unaffected, but older basic phones and some telecare devices may rely on 2G.
- Ofcom fined Virgin Media £23.8 million over a separate but related failure to protect telecare customers during a switchover.
- If a relative uses a telecare pendant, ask the provider now whether it already works on a multi network SIM.
Roo’s take: 2029 feels a long way off, and it is. That’s exactly why now is the easy, unhurried time to check, rather than the week it actually happens.
Frequently asked questions about the 2G switch off
- When is the 2G switch off happening?
- It’s staggered by network: EE from May 2029, O2 from summer 2029, and Vodafone during 2030, with full 2G and 3G retirement across the UK by 2033 at the latest.
- Will my smartphone stop working after the 2G switch off?
- No. Modern smartphones use 4G and 5G and will keep working as normal. The 2G switch off mainly affects older basic phones and a small number of specialist devices.
- Does the 2G switch off affect telecare alarms?
- It can, if the device hasn’t been upgraded to a multi network SIM. Many telecare providers have already made this change, but it’s worth checking directly rather than assuming.
- What happened with Virgin Media and telecare customers?
- Ofcom fined Virgin Media £23.8 million in late 2025 for disconnecting telecare customers during a separate landline digital switchover, after failing to properly identify who relied on their line for a personal alarm.
- What should I do to prepare for the 2G switch off?
- If you or a relative uses an older phone or a telecare device, contact the provider and ask whether it already works without 2G. There’s no need to act immediately, since networks won’t begin switching off until 2029 at the earliest.
