Why is my Tesco pay as you go sim not working?

Your Tesco pay as you go SIM might not be working due to several reasons. Common issues include insufficient balance, network coverage problems, or a faulty SIM card. Ensure your account has credit, check for any network outages in your area, and try reinserting the SIM or testing it in another device. If the problem persists, contacting Tesco customer service for assistance is recommended.
