When you first notice that you can't connect to your carrier's wireless network, you need to isolate the issue to see if it's with your device specifically or if the carrier is having a problem. If you have access to a computer, you can do this by searching online, like on the Down Detector, or by talking to other people on the same carrier. If you determine that it is not a network problem, but a problem specific to your phone, completely disconnect from all networks and reconnect to the Mobile Network only. Perform a soft reset on your BlackBerry if you still can't connect to your wireless network, or if you can connect but can't make or receive phone calls and transfer data. Perform a hard reset if your connection is not restored when the BlackBerry finishes booting up. Before you replace the BlackBerry's battery, remove and replace its SIM card to make sure it's seated correctly. Older CDMA BlackBerrys may not have a SIM card, so this does not apply to them. If after the device boots up, the BlackBerry still doesn't connect to the network normally, even after you replace the SIM and battery, contact your carrier for additional assistance. Sometimes the problem is just that the network has poor coverage where you are, in which case you should consider a cell phone signal booster. If your BlackBerry has the Android operating system installed and it's not connecting to the internet supplied by your carrier, reset the APN settings to default.
