Hi,
My provider is Telia Finland. At the moment, I cannot upload even a 1GB file without the drop. It is trivial to reproduce the issue with heavy uploads, but so far, I have not seen the same with heavy downloads. Did you encounter the issue also in 5G NSA mode only?
I just stumbled upon this thread describing very similar issues: Telekom Deutschland 5G NSA Issue
Teltonika’s reposnse is needed!
