Default Unlocking?

Please Login to Remove!

I have searched and read posts about unlocking the BB. The posts assume a level of knowledge I do not seem to have.

I know (I think) you c/n unlock a Vzw BB. I am currently a verizon customer. (Waiting for them to get a new BB in my lifetime)

But, if I switched to T-Mobile and unlocked the phone, would that allow me to use the phone network of other carriers?

Would it allow me to use the data network of other carriers?

I d/n travel outside the US, so does unlocking even matter?

Start over.
Verizon phones can not be used on other networks. Different technology.

What are you trying to do? Unlock a Verizon BB and use it on T-Mobile? Can't be done.

I understand that verizon phones or bb c/n be used on other carriers. What I am thinking of doing is adding a BB - keeping my verizon until I am out of contract.

Since I am thinking of adding a device, my question was about unlocking a BB on another carrier. If I go with T-Mobile, for example, will I be able to use the AT&T phone network? The AT&T data network? In addition to the T-Mobile phone and data network?

I am just a little fuzzy on exactly what the unlocking does.

Unlocking allows you to use one carriers branded device on another network. You can not normally use T-Mobile AND AT&T at the same time. They have roaming agreements in place to support each other where they have no networks, but you can't use both.

Unlocking is helpful if you travel and want to use a foreign SIM card in your phone. It does less with a BB. Unlocking is great if you want to take a Cingular 8800 and use it on T-Mobile (as I do). Unlocking is great if you want to sell a phone.

So, if you plan on unlocking the BB, you start with selecting the device. Then unlock for the network you want to use. Your BB is then restricted to that network for both data and phone?

How, if at all, is this reflected in the monthly bill? If you have T-Mobile, and unlock for AT&T, what about the number for the favs?

I know you did the opposite of this, Cingular to T-Mobile. Does your bill come from Cingular of T-Mo?
