AT&T offers two types of installation options: self-installation and professional installation.

 

The fee for self-installation costs $35, whereas the professional installation fee costs $99. Some plans may require extra equipment fees, but most are offered a Wi-Fi Gateway—a combination of a router and a modem. Select bundles may waive the installation fee.

CenturyLink Installation

 

CenturyLink also offers both self-installation and professional installation.

 

The professional installation fee costs up to $125 while the self-installation is free of cost but may have a fee for shipping and handling of equipment.

Depending on the bundles offered, the installation and modem fees may be waived.

AT&T Internet Contracts, Equipment Fees & Fine Print

 

AT&T’s contracts are typically a 12-month or 24-month commitment.

 

Bear in mind that the early termination fee costs can cost up to $180. For every billing cycle that’s late, the fee costs up to $10 per bill. Equipment fees are dependent on the plans or bundles offered, but most AT&T plans provide customers with a Wi-Fi Gateway. Equipment and installation fees might be eligible to waive depending on the bundles offered.

CenturyLink Contracts, Equipment Fees & Fine Print

 

CenturyLink offers contract-free plans, which allows customers to pay month-to-month with no cancellation penalties.

 

However, other bundles that include phone and/or TV services may have their own contracts with early cancellation fees. There is a flat, late payment fee of up to $15 per month plus a percentage (around 5%) of the unpaid bill. Equipment fees cost up to $50 for shipping and handling; the CenturyLink modem costs $15 per month on lease or a one-time fee of $150.

AT&T Internet Data Caps

AT&T’s standard data cap is 1 TB, with an additional $10 for every 50 GB. They do offer some plans with unlimited data; or customers can opt to add unlimited data for $30/month.

CenturyLink Data Caps

CenturyLink also has a 1 TB data cap but no additional fees for data overage. Instead, customers may experience certain restrictions or suspensions if data is overused frequently and/or excessively. You also have the option to purchase an additional 50 GB for $10.

Fantastic team and great coverage

on September 28, 2019

Absolutely fantastic! Tech came out to help install and, due to the wiring in our apt, it took a while to find the correct outlets. But he was so patient and helpful and kind, really going above and beyond to make sure things got set up so I could have the level of coverage needed to qualify for work from home. Truly amazing guy, I honestly can't speak highly enough of him. He kept trying long after I suspect most would have given up. Huge THANK YOU to AT&T for the coverage at the right price (literally half the price of the competitor in this area), and more importantly for having such an amazing guy on your team. Thank you.

Best coverage

on May 19, 2021

I travel often and I definitely travel around upstate New York and everywhere I go AT&T is faster and even seems to have more coverage than the others, so I am not sure who is doing the tests, but everywhere I have been, AT&T seems to outperform (also I don’t like AT&T as a company, so trust my honest review here).

100 Mbps CenturyLink Internet

on September 19, 2019

We switched to CenturyLink and could not be happier. It is so much faster, has never cut out and had the best installation customer service. The price is also great.

Love Centurylink

on June 18, 2021

We have had Centurylink landline for literally decades. It was a no-brainer for us to use them for internet and landline when we moved into our new home. Our home was built in an area with their new fiber internet. They installed it on the day scheduled, at the scheduled time. The technician was great. Had it up and running quickly. Have not had any problems. Both the internet and landline are cheaper than we were paying Cox for just the internet. Had a very bad experience with our previous ISP. Kept dropping calls. Hope to have Centurylink for decades to come.
