When Telecom define data usage, as a "MB", do they mean  1,000,000 bytes  (10 to the power 6 ) or 1,048,576 bytes (2 to the power 20) ?

I am fairly sure it's 2^20.

I assume you are talking about mobile in regards to MB.

I can ask around to confirm, do you have a specific issue this is in relation to?  Feel free to email me pl at telecom.co.nz and I can forward it onto someone who can answer it (pretty busy right now so I am not sure if I will be able to find the answer)

I'm presuming you are talking about broadband not mobile....

Given that they describe a GB a 1000 MB in their T+C, I'm thinking they mean 10^6

According to the IBM Dictionary of computing, when used to describe disk storage capacity, a megabyte is 1,000,000 bytes in decimal notation.

But when the term megabyte is used for real and virtual storage, and channel volume, 2 to the 20th power or 1,048,576 bytes is the appropriate notation.

Their old usage meter displayed data as 2^20 but their new one is the more ambiguous whole GB notation (e.g. 100GB). I'm guessing it is still counted as it used to be but you'd need word from the Telecom team to know for sure.

I am asking about mobile data.  I have a T-stick with 750MB cap.

So, Telecom Team, any word on this? How do you account your mobile and fixed line data consumption?

I was about to say who really gives a damn - its only 24 kilobytes per megabyte of difference.
Like those people that buy a 1 terrabyte hard drive and moan about being ripped off because its only got 970gb according to windows.

Anyhow I worked it out and i wont say that now because over 750mb it works out to be 18 megabytes of difference. 2.4% which on such a small data plan i can assume it really does make a difference to the op.

I can do a lot with 18MB and Telecom will charge me too much if I exceed the 750MB monthly limit.

I still don't know the answer to the original question?

Indeed, this seems like a question that would be simple to answer.

I can check Monday, as my mobile is also 750MB. Landline BB is the greater amount, as in 30GB - 30720MB

But from memory, my daughters mobile 1.5GB plan is 1536MB. (I recall that from excess usage!!) Not that teens ever use over the allowance....never.

well their GB is 1024MB

but it's only a guess

Hi

Thanks for posting the link.
So that means I need to know the MTU size in order to calculate how many bytes in a Telecom MB.
I know that the MTU for Broadband is 1500.  Is it the same for the XT Network??
Google can't find the answer for me.
