Just an FYI. Some ISPs have usage caps. Even with a VPN your download usage is recorded.
Here's Comcast's usage allowance, check your Comcast account for the usage cap in your area:
In the Nashville market, we will increase our data usage allowance for all tiers to 300 GB per month and also offer additional gigabytes in increments/blocks (e.g., $10 per 50 GB).
In the Tucson market, we will increase our data usage allowance for XFINITY Internet customers subscribing to the Economy tier through the Performance tier from 250 GB to 300 GB. In addition, those customers subscribed to the Blast! tier will receive an increase to 350 GB, those subscribed to Extreme 50 will be increased to 450 GB, and those subscribed to Extreme 105 will be increased to 600 GB (see table below).
XFINITY Internet Package New Data Usage Allowance
Economy 300 GB
Economy Plus 300 GB
Internet Essentials 300 GB
Performance Starter 300 GB
Performance 300 GB
Blast 350 GB
Extreme 50 450 GB
Extreme 105 600 GB
In both approaches, we'll be increasing the initial data usage allowance for our customers from 250 GB per month to at least 300 GB per month.
It's highly unlikely that anyone will go over 300GB/month, but not only file downloads are recorded as data usage.
