Frequently Asked Questions

What is a Data-only SIM plan?
A data-only plan includes a data allowance but no call minutes or texts. They can be used with SIM/eSIM enabled devices such as tablets, laptops, mobile broadband dongles or mobile broadband routers.
Can I keep my current mobile number?
Yes. If you have an existing mobile number you can transfer it over when you order your SIM card, simply enter the details at checkout and we’ll handle the rest.

You will need a PAC from your current network provider which you can get by texting the word PAC to 65075.

You can also choose to do this later after you order.
What happens if I exceed my monthly data allowance?
If you run out of data mid-month, you won’t be charged for any further usage but also won’t be able to use any services that require data. You can purchase additional 1GB, 3GB or 10GB data add-ons by contacting us via email help@mozillion.com.
