So I was flipping through my blacberry curve guide for ____s and giggles today and it clearly shows that even with no signal, as in nuthing, (Tx), that I am able to make emergency calls. If there is no network, how is that possible???
If the phone can detect any compatible signal, it will allow you to make a 911 call even though you cannot make other calls. There are government rules that requires this capability... so roaming agreements are not required to make emergency calls
But if my phone shows no signal, then there is no compatible signal available. Yet the guide said even with the signal strength indicator showing Tx, which means nada, no roaming no nothing, a 911 call can be made. when my phone shows Tx there is nothing available. Its a sprint curve so it will roam on verizon if available. But if neither of those networks, or any other cdma network are available, i dont see how it would be possible to make any kind of call.
I assume the guide is just referring to the situation where the phones shows no signal because the only networks it sees are blocked out by the phone.
