• 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 Wi-Fi® enabled device and your wireless service provider supports UMA, verify that your connection preference is not set
to Wi-Fi Only.

Depending on your BlackBerry® device model, the Wi-Fi® feature might not be supported.
About connecting to a Wi-Fi network
With Wi-Fi® 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 Wi-Fi network 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 Wi-Fi network, you might avoid data charges that are associated with using your
mobile network, and, in many cases, the connection speed is faster.
