never run out of credit,
top up any mobile with a quick text
Felix decided to go to the park with his mates after school, half an hour in he remembered his dad was meant to be picking him up.
After running back to school and finding it closed with no sign of dad and knowing he didn’t have enough credit to make a call he made his way back to the park. The park empty, no pay-phone in sight and out of credit on his phone, he didn't know what he was going to do.
When Felix took out his phone he saw he had a message from Beem, his mum had topped him up.
Felix called her straight away and told her where he was and explained what had happened, relieved she had topped him up she told him to sit tight and wait for her to arrive.
