This website has a calculator to show the expected upload/download time for different file sizes and bandwidths. In the example below, we uploaded a 17.9 megabyte file to Buzz on a 4G cellular Internet connection. With an upload speed of 1.40 Mbps, the file took one minute and 56 seconds (1:56) to upload. This result aligns well with the expected upload time highlighted in the chart below.
