No your Vz phone would not roam to a T-Mobile or AT&T tower. Now that they are not CDMA voice 3G it is theoretically possible but not their business model. Then there is the matter of frequency / bands. Think "in network" all the time.

Would I be correct to assume that if, for example, a Verizon tower is offline, your mobile phone would connect to another nearby Verizon tower? And that you could not only make voice calls and send text messages, but also use your phone as a hotspot for Internet? And that if there was no other Verizon tower in range, your phone would roam to a T-Mobile or AT&T tower? And in that case, could you still use the hotspot feature? Now, what about Home Internet service? Would I be correct to assume no roaming and probably not even another Verizon tower? If your designated tower is down, no home Internet? One last question, if the tower has power and all the electronics is running but the backhaul to the tower is down (like a fiber cut), do phones still connect to the tower but have no service? Or will they move to another tower?
