Step 2: Set a limit
Click Enter limit to set a monthly cap and get a warning near it.

Troubleshooting
Numbers don’t match my provider
Devices only count their own usage and may reset at different dates. Your provider’s figure is what you’re billed on.
Frequently asked questions
Do all home internet plans have caps?
Many don’t. Check your contract or provider’s website.
What happens if I go over?
Depending on the plan: extra charges, slower speeds, or nothing.
Summary
Check your provider’s app for official usage, use your router and device data usage settings to see what uses the most, and set warnings so you never hit your cap by surprise.
