Xfinity vs. AT&T data comparison

Data Caps

Both companies have a data cap of 1 TB. It may sound like a lot, but if you have several devices or family members streaming online games or movies, 1 TB goes quickly.  If it’s available to you, AT&T’s fiber internet has no data cap.

Overage policies and fees

You’ll need to be careful about your data overages and monitor them regularly. Xfinity will automatically charge you $10 for every 50 GB of data you use after 1 TB. If you don’t want to worry about going over your limit, you can pay an extra $50 per month for unlimited data.

AT&T DSL will charge you the same amount of $10 for every 50 GB in overages. You can add a $30 per month unlimited data allowance if you use a lot of data.

Xfinity speeds
