There are absolutely differences in signal quality in phones, but nobody ever mentions it because the equipment needed to properly test it is extremely costly and technical.
It's one of the things the LTT Labs are trying to set up to do. RF shielded test generator and a spectrum analyzer and generator... The spectrum analyzer by itself costs upwards of $100k USD.
So hopefully, eventually, you'll be able to see signal quality metrics from at least one place.
Have you considered Aldi Mobile? They use the telstra network with some towers excluded. I don't know if there's a way to look up what towers are excluded, but I was under the impression that it was remote towers where no competitors service.
I'm 100% for making stuff, Just be careful with makeing stuff like this, something to do with emergency/military signal interference can land you in the shit from what I have read, but if you got the skills and knowledge, bloody get em
Vodafone is good enough, mostly. The main advantage is that it's dirt cheap, I'm paying $25 a month for my phone and it's unlimited data. Not fast unlimited, but I don't get fast internet anyway so unlimited is still nice.
My first thought was to reply with something along these lines. They're guilty of so much shit, if you look up "Telstra controversy" and you'll find an endless list of shameful business practice.
We have to deal with them at the moment because we're staying with an elderly relative and her house, her rules - fair - and she is worried about switching providers. If something did go wrong and she lost her number, it would be pretty awful. So we're stuck with Telstra.
We're on our third modem with them in a little over a year (had to get a decent one, working from home). The absolute shit fight to get it replaced each time only served to reinforce that we are entirely correct on our views of their business. They have made it as tangled a web as Centrelink (another org that we have luckily not had to deal with in some time), and their customer service is basically non existent.
To their credit, their store staff did their best to help but their hands were so incredibly bound by red tape that there wasn't much to they could do. Also, the credit we were promised after the second go around was never applied to the account. Wasn't worth our time to chase it, because we actually value our time and have wasted enough of it.
And that's just one consumers experience.
The stuff they do on a national level is absolutely shameful. They need to be broken up.
Bless them! They're so generous to provide us with something new to listen to while we wait to talk to someone for over an hour, to ask them why we haven't been paid when we submitted a claim two months ago!
And then for some unlucky people "sorry your claim has been rejected, please start a new claim and have it assessed in a few months, and we'll back pay you to today, not two months ago".
I don't like how their monopoly suppresses the functionality of competitor services.
Also, they fucked me around a few years back. I got indebted thousands of dollars for something I didn't agree to, and threatened to get the ombudsman involved. The issue was resolved that same day.
Literally any MVNO is better than Telstra, Optus, or Vodafone. Go with Amaysim, Boost, Yatango, Vaya, one of the supermarkets' mobile plans. Shop around. Most of them use the Optus network, but some are on Telstra.
I'm using Internode Mobile, it's cheap, the plans are great, but it uses the Vodafone network. Internode has been a good company for me, they've consistently done right by me over my last 15 years as an ISP.
It's not that I owe them any loyalty, but I'm convinced if I ever have any issues then they'll take a loss, over an upset customer.
Internode was bought by TPG a long while ago and many of the original founding team started Aussie broadband with similar ideals. They'll end up selling that to TPG too probably, but right now they're ok and they have partnered with optus for cellular tower coverage.
By the way if you want to make informed decisions about cell tower coverage, there's an app called "aus phone tower" by bit bot software which gives you exact cellular tower information. Use that to figure out coverage before you choose a mobile provider network.
