- Running out: the plan's terms say what happens
What an allowance is
1 short paragraph
It is measured in gigabytes (GB) per month. Browsing, streaming, maps and video calls all draw from it. Wi-Fi at home or work does not use it.
When you run out
1 short paragraph
What happens next depends on the plan: some slow your connection, some charge extra, some let you buy more. We do not assume one, so check the plan's terms.
Unlimited plans
1 short paragraph
Plans described as unlimited can still have conditions, such as speed limits after heavy use or restrictions on tethering. Read the fine print on the provider's page.
Choosing a size
1 short paragraph
Check the data usage screen on your phone for your recent months. Most of the time on Wi-Fi means a smaller allowance may be enough. If you stream a lot away from Wi-Fi, size up.
Common questions
Does the allowance roll over?
That depends on the plan, and we do not assume it does. Check the provider's terms.
