I get that our phones can pick up signals from towers since they have a much stronger signal and enough power for that. But what doesn’t make much sense to me is how our phones’ tiny antennas can still produce a signal strong enough to reach the tower as well and create a two-way connection. How is that possible? Does the tower just pick up weak signals and strongly amplify them?

Think of the tower having really really sensitive ears. It can hear stuff that isn’t that powerful, there are lots of tricks and crazy physics that phones and towers use as well to help this. But towers at the end of the day are just really sensitive receivers. Its a lot easier to hear a faint signal (that is make a really good receiver) than you’d think, and your phone has actually enough power for that signal to go a few miles and still be heard.
