Alternative to dnf that restarts downloads without discarding?

I have recently moved from high speed broadband in Australia to the end of a very unreliable and slow internet link in regional Philippines. Now, dnf struggles to download during the day and often drops hundreds of megabytes of download in an update session when retries are exceeded. This is chewing up my limited Gb allowance. Is there an alternative method of download which will continue a half finished action? If I can't do it in Fedora, which I have used since the late 90s, is there another distro with a better downloader that I can switch to? Tearing my hair out.

By the way, dnf is the only download process across my laptop and two android devices which throws away precious downloads. Updates to Android work fine and even good old YouTube knows how to continue after an interruption, so it is not as though the technology is not well proven.

Any help would be greatly appreciated, as I am ready to upgrade to Fedora 32 and I'm not willing to risk it until this issue is sorted. "8-)
