I was just wondering how you pay for bolt ons using Pay as You Go. If for example I top up £15, and the Bolt On costs £5 per month, does it then take £5 every time I top up leaving me with £10? Or do I have to top up £20?
If you top up £15 the bolt on will leave you with £10 credit for everything else. If you did not top up again it would leave you with £5 credit and so on, until you have no credit.
