- BlackBerry® smartphones
When the BlackBerry smartphone user is roaming on another carrier network, the smartphone is unable to send or receive messages.
Carrier roaming may be set to Prompt in the Mobile Network settings, and the prompt to allow roaming on the mobile network may have been ignored.
The Carrier network the BlackBerry Smartphone has connected to while roaming may not allow a BlackBerry data connection.
The data plan being used may not allow BlackBerry data usage while roaming.
- From the home screen select Options, choose Manage Connections, Network and Connections, then Mobile Network
- Under Data Services from the drop down menu, change from Prompt to On.
Attempt to connect to another mobile network manually.
If the first two resolutions are not succesful, it may be that the service plan may not allow data while roaming. Contact the appropriate service provider for the BlackBerry smartphone.
