You can use your DCalling Account with every telephone connection, be it a landline or a cell phone. We recommend saving your phone numbers in your account at Telephone > Phone Numbers. For these numbers, you will not be asked to enter your card number every time you make a call, as our system recognizes your number automatically. If you use a number you have not saved in your DCalling account, you will be asked to enter your card number for identification.
Please note that any indivual phone number can only be saved in one account.
