Comcast Xfinity Prepaid Internet: An In-Depth Review and Guide

Discover everything you need to know about Comcast Xfinity Prepaid Internet, from its benefits and eligibility requirements to setup and payment options. Learn how this flexible internet plan can help you avoid contracts and save money.

What is Xfinity Prepaid Internet?

Xfinity Prepaid Internet is a pay-as-you-go internet service launched by Comcast in 2017. It offers 50 Mbps download speeds and 10 Mbps upload speeds, making it an ideal option for individuals with specific requirements:

  • Those who don’t qualify for Internet Essentials
  • People with short or poor credit history
  • Individuals who don’t want to pay a deposit
  • Temporary residents, such as students and renters

This flexible plan allows users to refill their prepaid internet services in-store, through their Xfinity account, or via the Xfinity app.

Speed Considerations

While 50 Mbps download speed might not be impressive, it’s sufficient for up to two devices streaming 4K video simultaneously. However, households with multiple users may experience bandwidth limitations.

How Does Xfinity Prepaid Internet Work?

Xfinity Prepaid Internet utilizes the same cable network as other Comcast plans. Network signals pass through a refurbished Xfinity gateway, a device that combines a router and modem’s functionalities.

After setting up the gateway, users have 30 days of internet access, after which they must refill their prepaid internet services.

Eligibility Requirements

To be eligible for Xfinity Prepaid Internet, you must:

  • Be at least 18 years old
  • Not have an active Xfinity service
  • Reside within one of the 40 states that Xfinity supports (check their website for an up-to-date list)

Additionally, having an outstanding balance from previous Xfinity plans might affect your eligibility, although specific details are unavailable.

Pricing and Fees

Here’s a breakdown of Xfinity Prepaid Internet’s pricing structure:

  • One-time fee of $35 for the Prepaid Starter Kit (excluding taxes and shipping)
  • One-time equipment and startup fee of $80
  • $45 every 30 days for the prepaid plan itself

You’ll own the Wireless Gateway upon purchasing the starter kit, meaning there’s no equipment rental fee. However, using your equipment isn’t an option.

Data Cap

Xfinity Prepaid Internet has a 1 TB data cap, which might be limiting for heavy 4K streaming users. If you exceed this cap, you’ll incur a $10 data overage fee per additional 50 GB used. Xfinity does offer an Unlimited Prepaid Plan for those who need more data.

Getting Started with Xfinity Prepaid Internet

To start using Xfinity Prepaid Internet:

  1. Check whether Xfinity offers prepaid services in your area by contacting them via Xfinity Assistant, phone, or in-store.
  2. Purchase the Prepaid Starter Kit, which includes 30 days of prepaid internet, a refurbished Xfinity Wireless Gateway, and a coaxial cable.
  3. Set up your Wireless Gateway by connecting it to a coaxial port and a power outlet.
  4. Create an account at and activate your service.

After 30 days, you’ll need to refill your prepaid internet service.

To make a prepaid payment, you can:

  • Use your Xfinity account to click the ‘Refill’ tab
  • Visit and enter your ZIP code, phone number, and payment information
  • Use the Xfinity Prepaid app and tap the ‘Refill’ tab

You can choose to pay for seven days ($15) or 30 days ($45) and set up auto-refill or pay your entire balance online.
