It used to be there were different iPhone models for AT&T and Verizon because they needed different antennas. Now they sell the same hardware for either carrier. I don't know if that means they stuffed two antennas in it, or if it's something more clever like a software adjustable antenna.
For a $900 phone I wouldn't doubt it if someone told me it had some kind of electronic switching to enable or disable different antenna elements, but I'm not the guy who's going to disect his iPhone to find out. -Adam ________________________________ From: AF <[email protected]> on behalf of Ken Hohhof <[email protected]> Sent: Tuesday, August 12, 2025 2:56 PM To: 'AnimalFarm Microwave Users Group' <[email protected]> Subject: Re: [AFMUG] mobile and 5G Home Internet when a cell tower is offline Well, that kinda sucks. If you’re a prepper, do you need to have 3 cellphones then?

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?
