How does uploading files affect data usage?

[kat.hayes]

If I upload a 10 megabyte file does that mean I use 10 megabytes of data for this or does it work out differently somehow?

Thanks.

That's how it works.

To my knowledge, data usage involves both upload and download.

you might also get charged for the TCP/IP packet headers/trailers.

It's not a case of "might".

These things are tiny though and would apply to downloads anyway.
