O2 Is Switching Off 2G in 2029 — What West Yorkshire Businesses Need to Know

26 June 2026 · 3 min read · Airedale Tech

Virgin Media O2 has confirmed it will begin switching off its 2G network in Summer 2029, following the same approach it took with the 3G shutdown completed at the end of 2025.

For most businesses this will pass without issue. But if you have devices — alarms, sensors, remote monitoring equipment, or any other connected hardware — running on a 2G mobile connection, you need a plan.

What's happening and why

2G is old technology. It now carries less than 0.5% of O2's network data but accounts for over 10% of its energy consumption. Retiring it frees up spectrum that can be reallocated to faster, more efficient 4G and 5G services — a genuine improvement for everyone.

The shutdown won't happen overnight. VMO2 will run regional trials ahead of 2029, temporarily (and in some cases permanently) removing 2G coverage in specific areas before the full network closure. Affected customers will receive advance notice of these trials, just as they did during the 3G shutdown.

Who is affected?

Mobile handset users — minimal impact

Most businesses upgraded their handsets during the 3G shutdown, switching to devices that support 4G Calling (VoLTE). If your staff are using reasonably modern smartphones, you're already covered.

If you still have older handsets that don't support VoLTE, you'll need to upgrade them before Summer 2029. This isn't urgent, but it's worth flagging if you're due a device refresh in the next year or two.

IoT and connected devices — action required

This is where businesses need to pay attention. A wide range of devices can connect to mobile networks using SIM cards, often without anyone realising they're running on 2G:

  • Intruder alarms and panic buttons
  • CCTV cameras with 4G/SIM backup
  • Remote site monitoring equipment
  • Environmental sensors (temperature, humidity, CO2)
  • Vehicle tracking and telematics
  • Vending machines, payment terminals, and kiosks
  • Agricultural or industrial sensors
If any of your devices fall into these categories, you'll need to check whether they support 4G data. If they don't, you'll be looking at device upgrades, possible SIM swaps, and in some cases changes to the software or platform the devices connect to.

What you should do now

You have until Summer 2029, but that's not as far away as it sounds — particularly if you have a large estate of IoT devices or ageing hardware that needs replacing on a planned basis.

Step 1 — Audit your connected devices. Make a list of anything in your business that uses a SIM card or mobile connection. Don't forget equipment installed by third parties (alarm companies, facilities managers, telecoms providers).

Step 2 — Check 4G compatibility. For each device, confirm whether it supports 4G data. Your supplier or manufacturer should be able to confirm this. If it doesn't, ask about an upgrade path.

Step 3 — Plan, don't panic. Most of this can be absorbed into normal hardware refresh cycles. The key is knowing what you have so you're not caught out when the regional trials start.
