Buying Guide: SIM Cards for the UK

Understanding SIM Cards

When I first started looking for a SIM card for my trip to the UK, I realized I needed to understand the basics. A SIM card (Subscriber Identity Module) allows my phone to connect to a mobile network. It stores my phone number and lets me access services like calls, texts, and data.
