When trying to send a text message to an iPad the error
'Phone number not found: Error code -17' occurs.
As the iPad does not have a SIM card, is it possible to send a text message to this device?
First seen in
Sophos Mobile Control as a Service 3.6
Sophos Mobile Control 3.6
The reason for this error is, that the Sophos Mobile Control (SMC) iOS app is not installed on the iPad.
What To Do
To successfully send a message to an iOS device without a SIM card follow these steps:
- Install the Sophos Mobile Control iOS app on the device.
- Depending on the way the app is installed, there are two possibilities how to proceed
- The app installation is triggered by an SMC server:
No additional steps are required, the app will be activated and configured automatically.
- The app is installed manually by the user:
The user has to open the app and enter the Sophos Mobile Control server manually.
Furthermore, he must enter the activation token, which can be found in the users Self Service Portal or in the "Internal properties" tab of the respective device.
Once the app was successfully installed, the user must allow the app to receive Push Notifications.
After following these steps, you can send out text messages to the iPad. These messages will be displayed in the SMC app after clicking on the Notification shown on the device.
