Creating content on the road: managing heavy uploads

Mobile networks allocate more capacity downstream, matching typical use, and roaming users also sit below that network's own customers in priority.

It helps with volume, not speed. Check the full-speed cap first: past it, large uploads take a very long time.

There is no universal figure, because file sizes vary with camera, resolution, bitrate and length. The way to get a real answer is to look at the exports from your own past work, multiply by the number of pieces you must deliver during the trip, then add ordinary working use and a revision round.

Speed tests emphasise the downstream direction, which is where mobile networks put more capacity. The upstream path is also more sensitive to signal quality exactly where you are standing and to how many people share the cell. Test by uploading a realistically sized file instead.

It removes anxiety about volume but does not solve speed. Many such plans define a full-speed threshold, past which large uploads slow noticeably. Judge them by that threshold rather than by the word unlimited, and read the terms on the plan's own page because they differ from one to the next.

Yes if the plan's terms allow it, but set the computer to treat the link as a metered network first, and pause cloud sync clients by hand as well. A laptop's background workload is far heavier than a phone's and it starts the moment it sees a connection.

Only after two confirmations: a copy exists on external storage carried separately from the camera, and the file at the destination opens and plays through. A completed progress bar is not evidence that the file is intact.
