The Phone number column shows the phone number of the device. The phone number is used for notifications, provisioning, and other information pushed to the device by SMS or WAP. The device user can change the phone number from within the DME client on the device (for instance if a new SIM card is installed in the device).
The phone number is stored in the database as it is reported by the phone, for instance 30116424. When the phone number is displayed on this page, it is automatically formatted according to the country of the device. If the phone in the example reports that it is a Danish phone, the number will be prepended with the Danish international calling code +45, and the number would be formatted according to Danish standards: +45 30 11 64 24.
