SIM Card Days: Bundle Size Divided by Daily Use
A SIM bundle's value is not its gigabytes alone; it is how many days those gigabytes cover. Dividing by daily use gives the answer that matters.
What is the SIM Card Days Calculator?
A SIM bundle lasts as long as its data divided by daily use. This calculator divides total gigabytes by daily megabytes to give the days of cover. Heavy days such as video streaming shorten the bundle, so treat the result as an average-use guide.
How to use it
- Enter the SIM bundle size in gigabytes.
- Enter daily data use in megabytes.
- Click Calculate SIM Days for the cover length.
Worked example
A 10 GB bundle at 500 MB per day lasts about 20.48 days.
How long does a 10 GB SIM last at 500 MB per day?

Frequently asked questions
What uses the most data?
Video streaming and video calls dwarf messaging and maps, so a video-heavy day can halve the expected life.
Should I buy a bigger bundle?
Compare the top-up price with a larger bundle. A small top-up mid-trip often costs more per megabyte than buying bigger upfront.
