AT&T Internet 300 Plan: The Basics

The AT&T Internet 300 fiber plan is the mid-tier plan offered by AT&T Internet with the aid of its ultra-fast fiber-optic network. Its availability is quite limited. But if you are one of the lucky lot residing in AT&T fiber-based areas (Check availability by cities below), you can subscribe to this plan at a very reasonable rate and enjoy a number of benefits like:

Symmetrical Internet Speeds

The best thing about fiber broadband is its symmetrical speed. You cannot only download a 1 Gig file in less than 30 seconds but upload it as well. Video conferencing, hard-core gaming, HD or 4K HDR streaming, backup of large files, and much more can be done on more than 11 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. 378 Mbps. And the upload speeds are experienced around 340 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 business dealings—you will never run out of internet data with the AT&T Internet 300. There are no data caps included in any of AT&T Fiber plans. So you can relax and enjoy ultra-fast internet without the worry of data overage fees.

HBO Max™ 30 Day Trial

As you subscribe to the AT&T Internet 300 plan, you will get access to HBO Max™ for the first 30 days of subscription at no extra cost. A good way to test the high speed and unlimited data delivered via AT&T Fiber.

Whole-Home Wi-Fi

As powerful as an AT&T fiber internet connection is, you need an equally powerful Wi-Fi to manage the connection. And AT&T knows just the right internet device for you. Some of its popular choices are BGW210, 5268AC, or NVG599 Wi-Fi Gateways, a combination of modem and router. You can rent the equipment for a $10 fee per month.

The whole-home Wi-Fi comes with a free AT&T Smart home manager app. The app lets you control your network remotely, set up parental controls, and much more.

The AT&T-provided internet device 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. You can learn how to do that with the help of our detailed guide on How to Use Your Own Router with AT&T Fiber.

99% Reliability

AT&T guarantees 99% reliability of its fiber-optic network. This lets you and your family surf, stream, play, and work on more than 11 devices, with ultra-low latency and a minimal spike in ping even during peak times.

Free Security Suite

The fiber-optic network is one of the most secure broadband connections. But AT&T provides additional security with your AT&T Internet 300 plan. You get a free internet security suite, powered by McAfee, which provides an additional layer of protection from cyber threats.

No Annual Contracts

There is no annual contract with any of AT&T's internet plans. So if you want to move someplace else, you don’t have to worry about an Early Termination Fee. However, if you subscribe to an AT&T bundle, which includes the DIRECTV or AT&T TV service, you may have to sign a contract and pay an ETF in lieu of early cancellation.

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

If there are any unexpected hurdles, the technician is prepared to deal with them and even call for additional help if required. Expensive — Professional installation costs money. And AT&T charges you a one-time $49 fee to set up your fiber connection. If however you subscribe to an AT&T bundle you can qualify for a waiver.
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. Inconvenient — Professional installation offers convenience in many ways. However, some aspects of it may prove to be inconvenient. For instance, if you 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.

A skilled technician won’t be there to offer any assistance unless you opt for professional installation.

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

AT&T is America’s largest fiber internet provider. However, the fiber-optic network comprises just one chunk of AT&T’s vast network infrastructure, available to some 36 million American residents. AT&T utilizes multiple technologies to deliver internet service to the residents dwelling in its 21-state coverage areas.

AT&T IPBB network, based on a mixture of copper and fiber cables, is more spread out than its pure fiber-optic network. IPBB connections are branded as AT&T Internet and deliver multiple speed tiers. Starting from 10 Mbps, and going as high up as 100 Mbps. If you want to subscribe to an AT&T internet connection, delivered by its IPBB network, check out our detailed AT&T Internet 25 Review, AT&T Internet 50 review, and AT&T Internet 75 Review.

AT&T Fiber serves less than 30% of households in its service territories, offering three-speed tiers. Have a look at the cities and neighborhoods that are equipped with AT&T fiber below.

Fiber-optic is the latest cutting-edge technology that has set out to deliver the fastest internet speeds in the world. The internet speeds via a fiber connection can go as high up as 1000 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 fibers in 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 has made it the most popular and coveted broadband type.
