If you're looking to get a new BlackBerry Q10 but one isn't available for your carrier, you still have options. Thankfully in most cases you can simply unlock your BlackBerry Q10 and use it on another carrier providing the networks are compatible (you can use a Rogers device on AT&T for example - more on this below).
Unlocking also proves useful if you are a frequent international traveler as you aren't confined to your carrier's roaming plan and can instead use a local prepaid SIM card in an unlocked device.
BlackBerry Q10 Unlocking Instructions
Once you have obtained an unlock code, whether by purchasing it from a third party unlocker or from your carrier, BlackBerry has made it really simple in BlackBerry 10 to unlock your phone.
Step 1: Go to Settings > Security and Privacy > SIM Card
Step 2: Scroll down to Phone Network Lock, and tap the Unlock Network button
Step 3: Enter your 8 digit unlock code, and hit OK.
Voila! You'll see a pop up message saying Network Code Entered Successfully! From there, you can put the SIM card from different carriers into your BlackBerry Q10 and run without a problem.
TAKE NOTE: You only have 10 tries to unlock your BlackBerry. If you enter the wrong code ten times, you're going to have a useless phone. So don't do it. Before you enter your code, double check you spelled it right. From there hit OK. If the code does not work, stop right then.
