Troubleshooting: Mobile network
I cannot connect to the mobile network
Try the following actions:
• If your BlackBerry® device uses a SIM card, verify that your SIM card is inserted in your device correctly.
• If your device normally connects to a CDMA network and your device supports international roaming, verify that your
device is in global roaming mode and that your SIM card is inserted in your device correctly.
• Verify that you have turned on the connection to the wireless network.
• Verify that you are connected to your wireless service provider's network. If you switched wireless networks manually,
your device remains connected to that wireless network until you select your wireless service provider's network again.
• If you have set a specific speed for wireless network connections, verify that you are in a wireless coverage area that
supports the connection speed.
• If you have a WLAN enabled device and your wireless service provider supports UMA, verify that your connection
preference is not set to WLAN Only.

About connecting to a WLAN
With WLAN technology, your BlackBerry® device can access the Internet by connecting to a wireless router or wireless access
point at your home, work, or in a hotspot area. Your device uses the WLAN instead of the mobile network to visit web pages,
send and receive email messages, and so on. When you connect to the Internet with a WLAN, you might avoid data charges
that are associated with using your mobile network, and, in many cases, the connection speed is faster.
Hotspots are available in many public places, such as libraries, airports, hotels, coffee shops, and so on. Some hotspots are free
to use, while others require payment. Your wireless service provider might provide an application for your device that allows
you to log in to a hotspot. If you do not have an application on your device, you might have to set up your own account online
and log in manually.
