Possessing or Supplying a SIM Farm? New Rules Apply
From 29 October 2026, new criminal offences relating to the possession and supply of SIM farms come into force across the UK.
The changes are contained in the Crime and Policing Act 2026.
What is a SIM farm?
A SIM farm is broadly a device capable of using five or more physical SIM cards simultaneously or interchangeably to make calls or send or receive messages.
These devices can be exploited to send large volumes of scam texts and facilitate telecommunications fraud.
What is changing?
Possession
Possessing a SIM farm will become a criminal offence. A statutory defence is available where the person can prove they had a good reason or lawful authority for possessing it.
Supply
Supplying a SIM farm will also become an offence.
For suppliers relying on the statutory defence, the Act requires, among other things, reasonable checks that the recipient will have a good reason or lawful authority to possess the device and the recording of specified information before supply.
Legitimate uses remain protected
The Act specifically recognises examples including:
• broadcasting
• public transport
• electronic communications networks
• freight tracking or monitoring
These examples are not exhaustive.
What should businesses do?
Businesses that possess or supply multi-SIM devices should review whether their equipment falls within the new definition and ensure appropriate procedures, checks and records are in place before 29 October 2026.
