Customer Reviews
Good internet, slow onboarding
I signed up for Business Fiber last month. The internet speed has been consistent, which is great for our daily operations. Installation took longer than I expected, about 3 weeks from order to active service, but the technician was professional. Customer service was helpful when I called about the delay, though it took a while to get through.
Smooth switch, solid performance
We switched our main office internet to AT&T Business Fiber, and I also got a few Business Smartphones for the sales team. The ordering process online was straightforward, and I appreciated the clear options for different speeds. Delivery for the phones was quick, they arrived in just a couple of days. Installation for the fiber took about a week and a half after placing the order; the technician communicated well and got everything hooked up efficiently. The internet speed has been really stable, much better than our previous provider. The smartphones also integrated easily with our existing business apps. I had one small question about our first bill, and the online chat support was responsive and cleared it up pretty quickly. Overall, the performance has been exactly what we needed for our expanding team, and the transition was surprisingly smooth.
Reliable service again
This was my third time getting service from AT&T Business, this time for a new location. I ordered a Small Business Wireless Plan and it was just as reliable as my previous experiences. Setup was easy and activating the lines went smoothly. They're consistently good, which is why I keep coming back for our expanding needs.

Anyone know if you actually get that $800 port-in credit they advertise? Or is it like super hard to qualify?
Thinking about switching my whole office over to AT&T Business fiber. How long does the install usually take? We can't really be down for days.
