Does Your Internet Have Data Caps? Guide to Data Caps for Top ISPs


You’re streaming, surfing and downloading to your heart’s content until … Oh no, what is that? You’re about to hit your internet data cap.

It’s not uncommon for providers to have data caps on home internet, but it can be confusing.

If you’re not sure which internet service providers have data caps, how much going over your data may cost or how to get no data cap internet, then you’re in the right place.

Internet data caps by provider

Many providers offer options to pre-purchase additional data if you know you will use a lot for the month or add unlimited data to your plan. For instance, if your Buckeye data usage is going to be high one month, you can pre-purchase an additional 150 GB of data for $15 — same price as the overage fee, but triple the data.

Brands like AT&T, which already offers 1TB internet, offer options to add unlimited data on select plans for a monthly fee, while for others, like Spectrum, data caps don’t exist. Some providers, like Verizon Fios, don’t have fees for going over your data cap, but may discontinue your service if you habitually exceed your data limit.

Managing your data caps

What to know about internet data caps

Data caps are provider-imposed limits on the amount of data you can transfer while completing activities online. The amount of data you use depends on your online activities.

For instance, sending and receiving emails may only use a few megabytes of data, whereas streaming one hour of TV or movies in HD on Netflix uses up to 3 GB of data. Imposing data caps or throttling your internet use is an internet service provider’s way of discouraging excessive use and taxing their bandwidth.

However, as interest in streaming services continues to grow, customers may think twice about which internet service provider they choose based on internet data limits.

According to Statista, the number of Netflix streaming subscribers in the U.S. has grown from 21.45 million in Q3 of 2011 to 73.94 in Q4 of 2020. So, between multiple streaming sources, online gaming, shopping online and more, do you need to be concerned about going over a 1 TB internet data cap? Probably not.

A data cap of 1 TB would let you stream every episode of “The Office” in HD — about 99 hours — more than three times every month.

If you are still concerned that your Netflix binges may send you over a data cap, you can follow our tips on streaming under a data cap, monitoring your data usage or taking a look at which providers have internet data caps or offer no data cap internet.
