What do you mean? I've operated at 99% packet loss plenty of times in the rural parts of Vietnam. The key is you can't use any of the websites or apps that are popular in North America / Europe.

The likelihood of even opening a TCP connection is going to be very low. For phase 1, stacks typically send 5 SYNs before giving up. So 95% of your TCP connection estabilishments will slowly fail due to timeout before you even get to phase 1 of the 3-stage connection estabilishment. To say nothing of actually transmitting or receiving any payload data successfully. Which you would have to many times to open a web page.
