Connect to the mobile network manually while using Mobile Hotspot
If your BlackBerry smartphone is connected to a GSM network, and Mobile Hotspot mode is turned on, you might have to
manually connect to the mobile network using your APN. To get the user name and password for your APN, contact your
wireless service provider. Depending on your wireless service provider, you might be able to enter up to two APNs.
On the home screen, click the connections area at the top of the screen, or click the Manage Connections icon.
Select the Mobile Hotspot checkbox.
If necessary, enter the APN name and APN login information for each of your APNs.
