FAQ - Wireless Data Networks
You can either click on a question to take you directly to the answer or scroll through to read all of them.
1. What network is BlackBerry available on?
RIM Wireless Handhelds operate over nationwide wireless data networks. The RIM 950 and RIM 957 operate over the Mobitex network, operated by service providers such as Cingular Interactive in the United States and Rogers™ AT&T® Wireless in Canada. The RIM 850 and RIM 857 operate over the DataTAC® network, operated by Motient Corporation in the United States and Bell Mobility in Canada. Free nationwide roaming is also offered. Back to top
2. What factors affect coverage?
Your BlackBerry handheld communicates using radio frequency just like a cellular phone, so coverage is affected by anything that interferes with radio waves. For example, you will generally find a stronger radio signal outside a building as opposed to inside. Back to top
3. What happens to my messages when I am out of coverage?
The wireless data network has a store and forward capability that prevents messages from being lost. If you have turned off the radio or have traveled into areas with minimal or no coverage, messages you send will be held at the handheld and messages sent to you will be stored by the network until the signal becomes strong enough to successfully communicate with the handheld.
This is a very useful feature if you are constantly on the move. You could, for example, compose a few messages while on the subway, issue the send command, and put the handheld back in the holster knowing that those messages will be sent upon returning to surface level. The same applies for messages sent to you while you are on the subway, in an airplane, or out of coverage - the messages will reach you once coverage is restored. Back to top
4. How do I tell whether I am in coverage?
In the top right corner of the Home screen, just below the Battery Life Indicator, you will see the Coverage Level Indicator. Just as with cellular telephones, the more bars that appear, the better the coverage you are in. Back to top
5. How can I ensure that the handheld has the best coverage possible?
For optimal coverage, keep the BlackBerry handheld in the holster on your belt. When out of the holster, the handheld should be kept in a vertical position in your hands or on a flat surface. Lying the handheld horizontally will reduce the ability to send and receive messages successfully and will consume additional battery power. Back to top
