Roaming
About roaming and international roaming
In most cases, your BlackBerry smartphone 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, the triangular roaming indicator appears at the top of the home screen.
If your smartphone 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 smartphone normally connects to a CDMA network and your smartphone 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.

About connecting to a Wi-Fi network
Your BlackBerry smartphone can use the Wi-Fi network instead of the mobile network to visit webpages, 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.
Hotspots are available in many public places. Some hotspots are free to use, while others require payment. Your wireless 
service provider might provide an application for your smartphone that allows you to log in to a hotspot. If you do not have 
an application on your smartphone, you might have to set up your own account online and log in manually.
If you have an access point or router that supports , you can connect to it using Wi-Fi Protected Setup.
