🤩 Helpful Tips and Additional Info

  • Choosing the Right SIM: If you're mostly using your SIM in the UK and need full mobile services like calls and texts, the Classic SIM is the way to go. However, if you're frequently traveling abroad and want a SIM that provides extensive roaming options, the Smart SIM is perfect

  • Data Needs: The Classic SIM offers more data flexibility with different plans, while the Smart SIM focuses on providing unlimited data on supported apps. Make sure to check if your favourite apps are included
