About roaming and international roaming
In most cases, your BlackBerry® device automatically connects to the appropriate wireless network when you travel outside your wireless service
provider's coverage area. Sometimes you might have to provide login information before you can access a wireless network. When you roam,
a triangular roaming indicator appears at the top of the Home screen.
If your device requires a SIM card, your wireless service provider might need to set up your SIM card with roaming services before you can roam.
If your device normally connects to a CDMA network and your device supports international roaming, you might need to get a SIM card that
is set up for international roaming from your wireless service provider. Your phone number stays the same when you travel internationally.
For more information about roaming and roaming fees, contact your wireless service provider.

strong signal. A reduced signal display might indicate increased power output from your device as it attempts to connect to a weak signal.
If the wireless coverage indicators display anything other than 1XEV, 1X, 3G , EDGE, GPRS, NXTL, MIKE, or NTWK, you might be in an area
of reduced wireless coverage where features such as email messaging and internet browsing are not available (you might only be able to make
a phone call or send and receive SMS text messages). If the SOS wireless coverage indicator appears, you can only call emergency numbers.
If the X indicator appears, you are in an area of no wireless coverage.
If your device includes Wi-Fi® support, a dimmed Wi-Fi logo with a network name displayed at the top of the screen indicates that your device
