How to add on to a sim only-monthly contract

[tiaatkins2024]

I pay monthly for day calls & messages however, I would like to pay for more data this month.

@tiaatkins2024  Then just purchase a data add on. You can do that HERE   You can not just add more data to your current tariff unless you request a change to your current contract to include more data and that means paying more each month.  Then you have to stay rate until you are over 12 months of your contract term before you can lower it back down to what you pay now.
