In fact, most major providers offer family plans to existing customers, so it’s worth checking if your current provider has any Family SIM deal programs in place.

Vodafone for instance, offers up to 15% off for existing customers while EE offers 10% off every additional line and a 1GB data boost. 

Parental controls on SIM

All major phone networks in the UK such as EE, O2, Three and Vodafone automatically block 18+ content – though this is via the data connection and not Wi-Fi. 

If your child primarily uses Wi-Fi, you may need other parental controls in place. Here’s how to enable parental controls on Android and on iPhone.

Additionally software like Qustodio and Net Nanny are some of the best parental control software that filter out inappropriate content to keep your kids safe online, while also offering tools to monitor and limit your children’s device and net use. 

Data capping or not?

Most often SIM plans will automatically stop service once you’ve reached the limit, or text you when you’ve used up a sizeable portion.

Parents, however, might still want to consider data or usage capping features when buying a SIM for a child. You might be prompted to sign up for this option when you buy the SIM from the network provider.  This helps limit charges that are out of contract such as picture messaging, long distance calls or additional data usage.

You can choose to set a £0 cap, which means your child won’t be allowed any additional spending outside the plan’s limits. Alternatively, you can set a budget beyond the base value of the plan if you want flexibility. This might be a helpful safety net for your child if they need additional minutes or texts to reach you. O2 for instance, allows a spending cap up to £200.
