I’ve noticed among myself and my friends that the 3G technology doesn’t work as well as it used to, or not at all. When I say not at all, i mean if our phones drop from 4G to 3G there will be little to no service available. Phone isn’t connected to the interwebs.

The wikipedia article on 3G has a section saying that some providers in some countries are starting (in 2020/2021) to decommission 3G networks, with 2G becoming the backup connection for phone/text. This might be causing the issue you are seeing, you should check the article to see if that applies to you.
However as mentioned by Target880, the problem could be a lack of any connectivity whatsoever (and your phone probably doesn’t provide a detailed explanation of what is happening) rather than worse performance by the 3G network. You might be able to get an app which provides more detailed information. Also your provider or a regulator might have maps of the 3G/4G/5G coverage in your area to check what services you are supposed to be able to access.
