There's a issue that's has to be looked after if someone buy 20 dollars add on for us roaming which is good for 10 days once its expired and user want to buy again its should let user to buy again right away without waiting 24 hours like one of our fellow user according to @Fina add on was expired on may 6th but when fina try to buy again was only able to see talk and text add on without data and data was coming as a seperate add on for 10 dollars 250 mb and because of that fina was bit upset since its was expired add on and I agreed with fina that once you have add on which is expired then its suppose to become available again right away without any wait time I think public mobile should look into it and resolve the issue
