I was looking for a tariff for my 10 year old son for a while and despite my reservations in wanting to get him a phone for many reasons, Parent Shield has definitely given me peace of mind. Not only does it give parents security and reassurance in knowing who can contact your child, but it is also very cost effective. Definitely worth the money! There are some lovely people you can speak to on the other end of the phone if you ever run into any issues. Graham certainly is very accommodating, helpful and nothing is ever too much trouble. Would recommend this to anyone who has kids! 5 stars!
