Check used smartphones are unlocked
If you’re giving your child a used smartphone, check that it’s unlocked. Locked phones generally need to stay with one mobile network and may come with network apps that your child doesn’t need. This bloatware may include games or apps that are not appropriate for younger users.
Unlocked smartphones also give you a better range of choices for mobile network and plans to help you save more money.
How to unlock your phone
Many smartphones will already be unlocked. However, if you try to enter a new SIM card from a different mobile network and it doesn’t work, it is locked. To unlock a smartphone, you will need to go to a professional.
Costs can vary, but a well-reputed local shop may be less expensive than going straight to the network. However, for greater peace of mind, ask the network provider in-store for the service.
