As technology moves forward at a rapid pace, there are some businesses that remain unaware that their older mobile phones – often referred to as ‘dumb’phones – will soon become obsolete. With the UK set to shut down its 2G and 3G networks by the end of 2024, these simpler devices, often favoured for their reliability, may become a serious risk for businesses. Not only could communication be disrupted, but scammers are also ready to exploit this transition.

Here’s what you need to know to protect your business and prepare for the changes.

What is Happening with 2G and 3G?

The UK’s telecom providers are moving to shut down 2G and 3G networks as part of an ongoing transition to faster, more reliable 4G and 5G services. These older networks, which have served businesses for years, are now considered inefficient compared to newer technologies. As a result, they are being phased out to free up bandwidth for more advanced services.

Who Will Be Affected?

If your business still uses devices that rely on 2G or 3G networks, such as older mobile phones, you are likely to be affected by this shutdown. These early mobile technologies won’t be able to connect once the networks go offline. Many SMEs that invested in basic phones for staff communication, logistics, or even customer service will find these devices rendered useless.

The Risks of Continuing to Use ‘Dumb’phones on 2G/3G Networks

Once the 2G and 3G networks are shut down, businesses relying on these devices may find they can no longer make or receive calls or texts. If your company uses these phones for key business operations – whether for driver communications, managing deliveries, or staying in touch with on-the-go staff – you could face sudden, unexpected disruptions.

Scammers thrive on confusion and change. With the end of these networks, fraudsters will likely target businesses that are unprepared. They could impersonate telecom providers, claiming they need to “upgrade” your services, or ask for sensitive information to “fix” issues caused by the shutdown.

One common scam method is Smishing – phishing through SMS – where fraudsters send text messages that appear to come from a legitimate source, such as your mobile provider, asking for details or directing you to a fraudulent website. As businesses navigate the transition away from 2G/3G, this type of attack could spike.

What SMEs Can Do to Protect Their Phone Vulnerabilities

With the shutdown of 2G and 3G looming, now is the time for SMEs to take action and ensure their technology is ready for the future.

1. Audit Your Technology

Start by conducting an audit of all mobile devices your business relies on. Check whether any of your devices are still using 2G or 3G networks. Even older devices that are used for non-critical tasks, such as backups or occasional use, could pose a risk.

2. Upgrade to Modern Devices

If your audit shows that any of your devices still use 2G or 3G networks, it’s essential to upgrade them to devices that operate on 4G or 5G. Not only will these newer networks offer faster and more reliable service, but modern smartphones also come with more robust security features, such as two-factor authentication (2FA), encryption, and the ability to install security apps that help protect your business from scams.

3. Educate Employees

Make sure your employees understand the risks associated with the 2G/3G network shutdown and know how to spot potential scams. Train them to verify any communications claiming to be from your telecom provider, especially those asking for sensitive information or payments. Simple steps, like calling the provider directly to confirm any requests, can help avoid falling victim to fraud.

Procrastinating on your transition away from 2G and 3G could leave your business scrambling to replace devices or update communication strategies at the last minute. And scammers often strike during these periods of confusion, making it more important than ever to be proactive. By preparing now, your business will avoid communication breakdowns and protect itself from potential fraud during the transition. Waiting until the networks go offline could cause costly downtime, disrupt operations, or worse, open the door for scammers to exploit your vulnerabilities.

So, Is Your Business Ready for the 2G and 3G Shutdown?

As the UK moves towards shutting down its 2G and 3G networks by the end of 2024, businesses that rely on these networks need to act quickly. Conducting a technology audit, upgrading your devices, and educating employees on the risks of fraud during this period are essential steps to keep your business secure and running smoothly.
