Why can't I get ATT internet?

Suddenlink & Frontier are the ILECs (incumbent local exchange carriers) in your area; they own the lines. Therefore, AT&T has no physical presence in those areas, nor can it. The only way you can circumvent that is to move to an area where AT&T controls the lines.

Because they are the LEC (line owners) AT&T can’t use their lines. Maybe you should blame every other provider that doesn’t service your area. Even better blame Elon musk for not providing satellite internet yet. 🤦‍♂️

I wasn't blaming providers. I just wanted to know why ATT can't be among our providers. Not sure why you responded the way you did. 

In essence  territories, someone paid to build the infrastructure, or a company bought another company asset for an area... 

In my zip code, 53188, ATT has about 90% coverage while the majority of the other 10% is CenturyLink who bought what was then rural area in the 1990s from Ameritech.

Most addresses have 1 telco provider (ATT, CenturyLink, Frontier, TDS, Verizon, Windstream, etc), 1 cableco provider (Comcast, Spectrum, SuddenLink, WOW, etc) 2 satellite internet providers of HughesNet or ViaSat.

For a new provider to come in they would have to build from scratch, example Google Fiber in select markets, who after spending years investing in a few markets decided to stop and consider providing service with wireless internet... ATT and Verizon are both doing the same with expanding 5G and 5G+ wireless to provide internet thru the air instead of hardwired fiber connections where it makes sense to do so. 

The ATT Fiber expansion with internet 1000 speeds reached 14+ million addresses within 21 state footprint, why? To meet the government condition of providing fiber to 12.5+ million addresses when receiving approval to purchase DirecTv summer of 2015. They had to reach this number within 4 years... thus 2016 to late 2019 was the DTV fiber purchase buildout. 

Where was some of the early deployments with larger percentage (14 million is about 18% of total addresses) of coverage up to over 90%? In markets where Google Fiber announced they would be entering.

New development in ATT hardwired footprint such as apartments, condos, residential subdivisions will receive fiber, existing brownfield on a case by case basis... outside markets, maybe? those with high population density would be the first to be considered...

AT&T plans to allocate capital into greenfield builds and is also looking at what the company can do out of region. The company is considering areas where it doesn’t currently have a traditional footprint, Donovan said.

“We’ve started the process of looking at certain cities like Minneapolis and Phoenix where we haven’t had a traditional footprint [in order to] get more fiber there to defend our position in satellite because there’s a marked difference in churn where you’re naked in satellite and where you have integrated broadband,” Donovan explained.
