Bell and Rogers actually don't share their towers in Canada.
but I would say don't cheap out on tech generally, because you'll get extremely weak security and nonexistent respect towards you as a customer.
smartphones is a dirty business. don't support the bad actors with your many, and then long term with your data
Bell and Rogers actually don't share their towers in Canada.
There is at least ONE exception in the US: Firstnet. They primarily use AT&T's towers, but they have some additional resources that other carriers don't have - they have additional towers and entire network bands that other carriers don't have access to. This allows us to still have coverage in natural disasters or network congestion times. In addition, if there's a natural disaster that knocks out coverage, they have satellite-based trucks that stage DURING the disaster, then come online as soon as it's over.
A few years ago, I had to ride out hurricane Ida in New Orleans (long story). The western eyewall passed directly over the house we were in, and the primary trunk lines coming into the city got destroyed by a cable tower that collapsed into the Mississippi. The next morning I had cell phone coverage when none of the other carriers had come back online yet. We didn't even have power, but my phone worked perfectly.
You have to be a first responder to join - you have to be added by your department's communications coordinator.
I believe what you say about networks using each other’s towers is incorrect for a large portion of the world. Where do you live?
Nah, cheap phones often have their bootloader unlocked/unlockable. Really happy with my POCO M5 running modified AOSP. Also, unlike every expensive phone nowadays, it has 3.5mm jack, SD card slot, and exceptional battery life for hiking/trekking (it survives 5-6 days as just a camera+map phone with all power saving on, in comparison people with flagships typically only last 2-3 days with the same usage and power-saving techniques).
I have a very low value lenovo tablet that my provider was giving away essentially for free (for worthless loyalty points I think). its BL cannot be unlocked, it has a special bootloader that does not implement the standard unlock commands.
Other than that, I have to admit I don't often deal with cheap phones, because my experience was that not even LOS supports a lot them. Maybe that's changed though.
Yes, that can happen sometimes, but I find that there are plenty of cheap options with unlocked bootloaders if you look for them.
