As stated, does AT&T have an equivalent? Thanks.

As far as i know, AT&T only has a 4G home internet offering. It's a lot slower and more expensive than the T-Mobile 5G home internet. Geared toward rural customers who don't have any other options.

Verizon offers home 5G that's comparable to T-Mobile.

It's not exactly equivalent, but they do have the Fixed Wireless for out in rural areas

But there's no direct competition to T-Mobile yet. Starlink is an option, and there's the resellers of the ATT plans like Nomad Internet.

What's your use case?

Even if you try to get AT&T wireless home internet by other means, they'll try to shut you down. AT&T is so strict. They don't wanna innovate. And they know their spectrum is the best coverage in rural Texas.

T-Mobile doesn't care where you stick their SIM card. All they care about is you keep paying them.

There's another thread somewhere discussing ways of rigging up wireless home internet with unlimited phone plans. I put together a WE-826T2 Chinese router that has a LTE modem for TMobile Unlimited phone plan. Works great when it works. At this point it's cheaper get the TMobile Home Internet.
