This is not something that needs a best-before date, you would say (your car key does not have a best-before date, does it?).

This is a simple microchip on a piece of plastic which stores authentication information that allows you to open access to mobile networks. The validity of a physical local SIM cardĪ local SIM card is a key that your mobile phone needs in order to connect you to the mobile network.

This is probably a smart trick played by mobile operators in an attempt to make more money. Just like the validity of a credit card, your calling credits or data credits can also expire. How did it happen that your prepaid calling credit or local SIM card expired? This is something very annoying and difficult to understand for a consumer.
