What is a Tesco Mobile Top-Up?

A Tesco Mobile top-up is a process of adding prepaid credit to your Pay As You Go (PAYG) mobile phone account. By adding credit to your tesco-mobile plan, you can make phone calls, send text messages, and purchase data bundles. When you complete a tesco pay as you go top up, the funds are instantly applied to your balance. This credit allows you to use your mobile device until the prepaid balance runs out, at which point you will need to complete another tesco mobile top up to restore your services.
