Hi ​@Theresa Acheampong 

Have you downloaded the bill that is showing the increased charge?
The bill will show the individual charges incurred i.e. calls, texts, data etc, and you can then determine what (if any) out of plan costs you have had to pay for, if any e.g. use of short codes.

This info informs you about the different OOP charges:-

If you don’t want any surprise costs then you can cap your bill.
Set it to the maximum £ you want to pay then you will know that your bill will be no greater than that month to month:-

Tap on Bills, scroll down to Manage bill cap, move the slider to where you want and click Save.

Good luck x
