Troubleshooting

I cannot connect to a wireless network
Depending on your BlackBerry® device model and wireless network, this feature might not be supported.
Try performing 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.
• Check that you have turned on the connection to the wireless network.
• Check 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, check that you are in a wireless coverage area that supports the
connection speed.
• If you have a Wi-Fi® enabled device and your wireless service provider supports UMA, verify that your connection preference is not set
to Wi-Fi Only.
