• Spectrum Re-allocation:
  The radio frequency spectrum utilised by 2G and 3G networks is being re-allocated to facilitate the expansion and enhancement of 4G and 5G services.
• Infrastructure Modernisation:
  The maintenance of legacy 2G and 3G infrastructure presents increasing logistical and financial challenges. Newer network technologies offer improved performance and energy efficiency.
• Technological Advancement:
  The growing demand for high-bandwidth mobile data and advanced communication services necessitates the deployment of 4G and 5G networks, rendering older technologies increasingly obsolete.
• Energy Efficiency:
  Newer network technologies are more energy efficient, and this is a major driving factor in the switch over.

The decommissioning of 2G and 3G networks is a strategic move to optimise the UK's mobile network infrastructure, ensuring its capacity to support future technological advancements and evolving user demands.

2G Switch-Off: Q&A

General Information

• Q: What is the 2G switch-off?
  A: It's the process where mobile network operators are decommissioning their 2G (second-generation) mobile networks. This means the infrastructure supporting older services like basic voice calls and text messages will be shut down.
• Q: Why is the 2G network being switched off?
  A: To free up radio frequencies (spectrum) for more efficient 4G and 5G networks.
  To reduce the costs of maintaining outdated infrastructure.
  To promote the use of modern, faster, and more efficient mobile technologies.
• Q: When will 2G be switched off?
  A: UK mobile network operators have agreed with the government to switch off 2G by 2033 at the latest. However, individual operators may begin to phase out 2G services before that date. It is important to know that operators are at different stages.
• Q: What about the 3G switch off?
  A: The 3G switch off is already underway in the UK. Vodafone and EE have completed their 3G switch off, Three are nearing completion, and O2 are planning to complete their switch off in 2025.

Impact and Devices

• Q: How will the 2G switch-off affect me?
  A: If you use an older mobile phone that only supports 2G, it will no longer work for voice calls or text messages.
  Devices like some older alarm systems, tracking devices, and certain smart meters that rely on 2G will also be affected.
• Q: Will my old mobile phone still work?
  A: If it's a 2G-only phone, no. If it supports 4G or 5G, it will continue to work.
• Q: What about emergency calls?
  A: After the 2G switch-off, you'll need a 4G or 5G-enabled phone to make emergency calls over the mobile network.
• Q: I have devices that use 2G for machine-to-machine (M2M) communications. What should I do?
  A: Contact your device providers to discuss upgrading to 4G or newer technologies. This is very important for businesses that rely on these devices.

Solutions and Alternatives

• Q: What if my phone is 2G-only?
  A: You'll need to upgrade to a 4G or 5G-compatible phone. Contact your mobile provider for upgrade options.
• Q: How do I know if my phone is 2G-only?
  A: Check your phone's specifications online or in the user manual. You can also check your phone's network settings or contact your mobile provider.
• Q: Will Wi-Fi calling be affected?
  A: No, Wi-Fi calling uses your broadband internet connection, not the 2G network.
• Q: What are the main network operators doing?
  A: Operators are communicating with customers who may be affected.
  They are working to improve 4G and 5G coverage.
  They are providing information on upgrade options.

Key Considerations:

• Ofcom is overseeing the switch-off to ensure minimal disruption.
• Mobile network operators are expected to provide support for vulnerable customers.
• It is very important to contact your mobile phone provider for the most up to date information regarding their switch off plans.
• The 3G network switch off is well under way, so if you have a 3G only device, that will also soon be obsolete.
