How to Deal with iPhone / Samsung Locked SIM or Network Lock Errors in the UK Understanding SIM and Network Locks In the UK, many iPhone and Samsung devices come network-locked, meaning they can only be used with the carrier they were sold with. When a user inserts a SIM from a different provider, the phone may display “SIM Locked,” “Network Locked,” or “Invalid SIM.” These errors prevent calls, texts, or mobile data until the device is unlocked. Understanding the type of lock is crucial for a proper solution. Types of Locks Carrier Network Lock: The phone is tied to a specific UK provider like EE, Vodafone, Sky, or O2. SIM Lock: Prevents using SIM cards from other carriers. Region or Firmware Lock: Rare, but some imported devices have region restrictions. iCloud / Samsung Account Lock: Does not allow activation on a new network until the account is unlocked. Step-by-Step Solutions for UK Users Verify the Lock: Insert a SIM from...
