Hi @Brandon, the credit is deducted only for the monthly renewal of the offer. The offer cannot be deactivated because we do not have pay-per-use pricing. If you don't intend to use the number at the moment, just don't top up. The month of validity of your offer begins when your remaining credit becomes positive again, so you don't waste a single day. Below is the link with all the info: https://supporto.ho-mobile.it/t5/Soluzioni-per-passare-a-ho/Tutto-sull-editore-ho/ta-p/126 I remind you that the SIM I have. it is valid for 12 months from the last top-up. To update the expiration date of your SIM, simply top it up. I remain available. Good evening.
