Internet Data Caps compared

What Internet Providers have bandwidth data caps, and how they compare
2021-01-02 (updated: 2021-03-02) by

Data caps are limits on how much information can be transferred/received per month, imposed by your Internet provider. Many Internet Service Providers (ISPs) implement some type of data cap to control costs and manage usage. Going over that data cap can cost you, depending on the provider you have. Streaming high-definition content, video conferencing for work and school, it can all add up. Below is a list of ISPs, along with their corresponding data caps, and additional costs of bandwidth once you go over those caps. Some providers may give users a grace period before charging for additional data. Also, some have temporarily suspended data caps during the 2020 Covid-19 pandemic.

Browsing web pages and sending/receiving emails uses very little data. The largest data usage by far is caused by HD/UHD video streaming, followed by P2P transfers and video-conferencing.
