Is iPhone cellular data limit enforcement in third-party apps?

Question

I don’t know anything about developing iPhone, but I’m developing a proposal for other people to do work on creating an application that interacts with existing systems and data.

I need to know if the restriction on downloading 20 MB cellular data is respected for all applications created by apples, SDK for third-party applications - i.e. if I developed an application trying to download a larger file, will it fail?

Context:

The data file we use is about 50 MB, and many of our clients work on the road and do not have Wi-Fi access. If the limit is met, I need to enable HTTP Range header support on our server and add it to the application requirements so that the file can be downloaded using 20 MB blocks.

thanks

Answer 1

No. The 20 MB limit is the one imposed by the app store itself. The only restrictions observed in third-party applications are those that the mobile provider wants to provide (which usually means bandwidth limitation or excessive fees if you go to the download cache). However, it may be useful to maintain the HTTP range anyway, in case of interruption in the download, and you want to resume it.

Answer 2

It applies; I did not understand your other points.

Answer 3

The limit exists for downloading both applications and media files (videos, podcasts, etc.), so I assume that it is limited for downloads in each application.
