We can supply O2 coverage sim cards however we are not responsible for any issues with the sim cards as this is the network providers responsibility. This option will be visible when you place the order with the watches. Please check what cell network works in your area before purchasing a sim card. A 3GB Nano sim is required for our tracking products (Childrens Watches/Pet Trackers).. If at anytime your are not satisfied with our products after purchase you have 14 days to inform us and return any items. We would also need to have the items posted back before any replacements are sent out.
