2G switch-off: every UK network's date, and the devices you need to check

Published 23 September 2026 · 8 min read

A GPS asset tracker of the kind that often still runs on a 2G SIM

Every UK network has now put a date on switching off 2G, and the dates are closer than most businesses think. Almost none of this affects your phones. It affects the equipment that has been sitting in a cupboard, a lift shaft or a van for the last decade, quietly using a SIM nobody remembers buying. Here are the confirmed dates from each network, what they actually mean, and how to find the devices that will be caught out.

The 30-second version

  • EE starts from May 2029. O2 starts in summer 2029. Vodafone switches off in spring 2030. Three has never had a 2G network.
  • Every operator has told the Government that 2G will be gone by 2033 at the latest.
  • These are start dates, not single shutdown days. Local trial switch-offs come first, with notice.
  • 3G has already gone on all four networks, so anything that used to fall back from 3G is now sitting on 2G with nothing underneath it.
  • Your phones are fine. The risk is alarms, card terminals, trackers, telemetry and lift phones.

Every network's 2G date

These come from the networks themselves and from the Government connectivity timeline, checked in September 2026. They are the dates the switch-off begins, not the date every last cell goes quiet.

Network2G switch-offWhat it means in practice
EEFrom May 2029EE will begin a nationwide retirement from that point, after localised trial switch-offs
O2From summer 2029Announced in June 2026. Local trials first, as with its 3G switch-off
VodafoneSpring 2030Vodafone has refined its original "during 2030" wording. Pilot closures in some areas will come earlier
ThreeNo 2G networkThree has never operated 2G in the UK. After the merger, VodafoneThree has only the Vodafone network to retire
All operatorsBy 2033 at the latestA firm commitment given to the Government that no 2G or 3G service will run beyond 2033

If you have read an older article saying EE is switching off 2G in 2030, that figure was never EE’s 2G date. May 2029 is what EE publishes on its own business and consumer pages, and it is what the Government timeline records.

These are start dates, not switch-off days

None of the networks will flip a national switch. All three that have 2G will run localised trial switch-offs first, turning it off in selected areas to see what breaks before going nationwide.

That matters for planning, because it means some sites will lose 2G well before the headline date, and you will not necessarily be the one who notices. Under the 2G Switch-off Charter, published in March 2026 and updated in September 2026, the signatories committed to two things worth knowing:

  • At least three years’ notice of the date a 2G network switch-off begins.
  • At least three months’ notice to affected customers before a trial switch-off in their area.
  • Checking 4G or 5G coverage is genuinely there before switching 2G off in a location.
  • Flagging life critical services to the Government, and reporting progress quarterly.

Who gets the notice?

The notice goes to whoever holds the SIM contract. If your alarm company or your tracking supplier owns the SIM, the warning letter goes to them, not to you. That is worth a phone call to check.

Why this matters more now that 3G has gone

The 2G dates would be less urgent if 3G were still running underneath. It is not. All four networks have completed their 3G switch-offs, and Ofcom confirmed in August 2026 that 3G in the UK is now off.

EE and Vodafone finished in early 2024, Three in November 2025, and O2 completed last. For a business this has a specific consequence: any device that was set to prefer 3G and drop to 2G when 3G was unavailable has already made that drop. It is running on 2G today, and 2G is the last rung on the ladder. When that goes, the device does not degrade. It stops.

One that has already bitten

O2 withdrew 2G access for inbound international roaming in October 2025. If any of your equipment uses a foreign or roaming SIM, which is common with trackers and some alarm signalling, it may already have lost coverage on the O2 network without anyone raising it.

The devices that need checking

2G is cheap, low power and good at getting a tiny amount of data out of an awkward place, which is exactly why it ended up in so much equipment. The devices below are the ones that come up again and again.

EquipmentWhy it is often on 2GWhat usually happens
Card payment terminalsOlder portable and mobile terminals shipped with 2G backupPayments stop, usually at the worst possible moment
Vehicle trackers and telematicsFitted years ago, cheap to run, rarely revisitedThe vehicle silently disappears from the map
Alarm diallers and signallingOlder panels use 2G for the signalling path to the monitoring centreThe panel looks normal, the monitoring centre stops hearing from it
Telemetry and meteringTank levels, pumps, environmental sensors, remote metersReadings simply stop arriving
Lift emergency phonesInstalled with the lift and never touched sinceA safety requirement stops working
Vending and unattended machinesSmall data needs, long service lifeCashless payment and stock reporting fail
Lone worker and telecare devicesLow power, wide coverageA safety device fails quietly

The pattern is the same throughout: these devices fail without telling anyone. That is what makes a deadline four years away worth a couple of hours of attention now.

How to check, in an afternoon

  1. Pull every SIM you pay for onto one list. Include the ones on supplier bills, not just your own mobile account. Unexplained SIMs are almost always these devices.
  2. Ask one question across the business: does anything other than a phone use a SIM? It reliably turns up more than people expect.
  3. For each device, get three facts: what it is, where it is, and which network and technology it uses. The supplier who maintains it will know, and should put it in writing.
  4. Separate the 2G-only from the rest. Anything 4G capable is fine. Anything 2G only needs a replacement date and a budget line.
  5. Ask suppliers who own their own SIMs what their 2G plan is, and when they will contact you. Get a date, not a reassurance.

The useful question to ask a supplier

Not "is this affected by the 2G switch-off" but "is this device 4G capable, and if not, what is the replacement and what does it cost". The second question gets a straight answer.

What to do with the answer

Most businesses find a handful of 2G-only devices, not hundreds, and the cost is in the hardware and the engineer rather than the connectivity. Spread across three years that is a budget line, not an emergency. Left until 2029 it becomes a scramble for engineer visits at exactly the moment everyone else wants one.

Where equipment is being replaced anyway, this is the moment to think about coverage rather than just cost. A device in a lift shaft, a plant room or a rural yard is the sort of place a single network struggles, and a multi-network SIM that can use whichever network is strongest often solves a problem that has been annoying people for years.

Frequently asked questions

There is no single date. EE begins from May 2029, O2 from summer 2029, and Vodafone switches off in spring 2030. Three has never had a 2G network. Every operator has committed to the Government that 2G will be gone by 2033 at the latest.

Almost certainly not. Modern handsets use 4G and 5G, and moved off 2G long ago. The exceptions are very old handsets and some basic phones, which will need replacing.

No, because Three has never operated a 2G network in the UK. Following the merger with Vodafone, VodafoneThree has only the Vodafone 2G network to retire, in spring 2030.

You can, but the equipment is only half the problem. Localised trial switch-offs will begin before the headline dates, and engineer availability gets much worse as a deadline approaches. Finding your 2G-only devices now costs an afternoon.

The supplier who installed or maintains it will know, and so will whoever provides its SIM. If neither can tell you, that in itself is worth following up, because it usually means nobody is monitoring whether the device is still reporting.

Find the 2G devices before the network does.

Tell us what equipment you have and we will work out what is affected, what it needs instead, and when it makes sense to do it.
