AT&T Internet 300 Plan: The Details

The AT&T Fiber Internet 300 is the starting speed offered by AT&T with the aid of its ultra-fast fiber-optic network. Its availability is more limited than desired. But if you are one of the lucky lot residing in an AT&T fiber-serviced area, you can subscribe to this plan at a very reasonable rate and enjoy several benefits like:

Symmetrical Internet Speeds

The best thing about AT&T Fiber 300 is its symmetrical speed. You cannot only download a 1 Gig file in less than 30 seconds, but upload it as quickly. Video conferencing, hard-core gaming, HD or 4K HDR streaming, backup of large files, and much more can be done on up to 12 devices at the same time.

The AT&T Internet 300 download speeds are expected to be up to 300 Mbps. But AT&T has recorded higher actual download speeds, which reach approx. 398 Mbps. And upload speeds are experienced at around 365 Mbps―more than the expected 300 Mbps.

Unlimited Data Allowance

Whatever you do on your AT&T Fiber connection—play online games, stream all day, power your smart devices, conduct video conferencing—you will not run out of internet data with the AT&T Fiber Internet 300. There is no data cap on any of AT&T Fiber plans. So, you can relax and enjoy ultra-fast internet without the worry of data overage fees.

Next Gen AT&T All-FiTM

As powerful as AT&T Fiber is, you need equally powerful Wi-Fi to manage the connection. And AT&T knows just the right internet device for you. The All-Fi setup includes the latest AT&T Gateway―its tri-band technology is able to power multiple devices, and optimize each connection. The equipment is provided to you with all AT&T Fiber internet plans without any additional cost.

The exclusive AT&T Wi-Fi Gateway delivers a powerful connection via Wi-Fi 6 technology, and is equipped with advanced mesh technology that enables excellent wall-to-wall coverage. Plus, the equipment comes with many useful features including parental controls. This makes the service all the more ideal for family homes that are packed with smart and internet-enabled devices. The free AT&T Smart home manager app lets you control your network remotely, set up parental controls, and protect your network security while doing much more.

The AT&T-provided internet equipment is mandatory for your internet connection to work smoothly. You can use your own router, but you will have to configure it with the AT&T gateway device. Learn how to do that with the help of our detailed guide onHow to Use Your Own Router with AT&T Fiber.

AT&T Internet 50 Modem & Router

99% Reliability

AT&T guarantees 99% reliability of its fiber-optic connection. This lets you and your family surf, stream, play, and work on more up to 12 devices, with ultra-low latency and a minimal spike in ping even during peak times.

No Annual Contracts

There is no annual contract required for the AT&T Internet 300 plan. Unlike, AT&T High-speed Internet plans there is no promo period with AT&T Fiber Internet. And so if you want to move someplace else, you don’t have to worry about an Early Termination Fee (ETF). It is applicable only if you cancel the subscription before the end of the promotional term.

Luckily, this is not the case with AT&T Fiber Internet 300 plan. You will not be bound by an annual contract and an ETF, and you can cancel anytime without any worry!

No Price Hike After 12 months

The best part about how AT&T now offers its Fiber plans is there is no price hike after the first 12 months. Meaning the AT&T Internet 300 price for the first 12 months is the same as the AT&T Internet 300 price after 12 months. You start paying at a highly competitive standard rate, and there is no hike after 12 months as with promotional offers.

AT&T Internet 300 Installation: Pro Vs Self-Install

What Should You Choose?


  • Smooth—AT&T sends out a technician to your home on the day of the installation appointment if you opt for professional installation. The technician is skilled at the installation task. And is likely to have conducted the process hundreds of times before. So, you can rest assured the installation will go smoothly. If there are any unexpected hurdles, the technician is prepared to deal with them and even call for additional help if required.
  • Safe—A layman may have a difficult time figuring out messed-up wiring, and would never expect it to be remotely dangerous. But there are never any guarantees when it comes to household wiring. Tampering with it may cause you to harm or obstruct the installation process. However, the process is as safe as it can get, particularly when a skilled technician is working on it.


  • Expensive—Professional installation costs money. And AT&T charges you a one-time $99 fee to set up your fiber connection. This is a huge deal-breaker when you have a completely free-of-cost self-installation option.
  • Inconvenient— Professional installation offers convenience in many ways. However, some aspects of it may prove to be inconvenient. For instance, you might have to take a day off work or arrange for someone (above 18 years of age) to supervise the process. Installations are usually quick and easy. But unexpected issues may arise, and take up a chunk of your time.

AT&T Self-Installation


  • Free— The best thing about the AT&T Self-install kit is that it is completely free. You can ask for a self-install kit while ordering your AT&T Internet 300 plan. The kit arrives within 2 to 3 business days. This saves you from spending a hefty amount on professional installation.
  • Quick Work—The AT&T self-installation kit is designed to make the process quicker even if performed by the less tech savvy. The kit boasts it doesn’t require any advanced technical skills or tools, and can accomplish the task in a minimum of 30 minutes if you follow the the AT&T Internet self-installation instructions that are enclosed.


  • Technical Skills—the AT&T self-install kit assures that no advanced tools and technical skills are required to get the job done. But each household and its setup is unique. And unexpected issues may arise, which an ordinary DIY fan may not be equipped to handle.
  • No Help— If you hit a snag during the self-installation process, you will have to resolve it by yourself. A skilled technician won’t be there to offer any assistance unless you opt for professional installation.

Note: Option to self-install is only available if your residence is pre-wired along with an ONT in place.

AT&T Fiber Internet 300 Network: How it Works?

AT&T utilizes multiple technologies to deliver internet service to the residents dwelling in its 21-state service territory. And ranks as America’s largest fiber internet provider with around 39 million residents under its coverage. However, the fiber-optic network comprises just one chunk of AT&T’s vast infrastructure.

AT&T Fiber serves households in over 32% of its footprint offering five speed tiers.

Fiber-optic is the latest cutting-edge technology that has set out to deliver the fastest internet speeds in the world. Internet speeds via an AT&T Fiber connection can go as high as 5000 Mbps. Download and upload speeds through a pure fiber-optic connection are the same which no other broadband type is capable of delivering.

AT&T makes use of fiber cables, which are made up of tiny optical fibers. These fibers are extremely thin, 1/10th the size of human hair. Each optical fiber consists of a core made of glass through which light passes. A plastic cladding surrounds the core. Data moves through these optical fibers in the form of light pulses and is carried faster than any other medium. The core and its cladding ensure the data is carried securely over a long distance and stays safe from theft and deliberate interruptions.

Higher security, speed, and bandwidth delivered via the fiber-optic networking tech have made it the most popular and coveted broadband type.

AT&T Fiber Internet Plans & Speeds: Find Your Fit

AT&T Fiber offers five speed tiers, which deliver symmetrical speeds. Meaning the same download and upload speeds. Starting from 300 Mbps internet, going up to 500 Mbps, 1,000, 2,000, and 5,000 Mbps.
