WhatsApp and Signal will strongly reduce bandwidth if you're routing your call through their servers. You can disable that (which does expose your IP address to the other side) and let standard P2P traffic do its thing. You'll still need good net neutrality laws for the calls to be of any useful quality (RIP video calling in the US for the next four years or more I guess) but the bandwidth problem is usually artificial.
Even Telegram has encrypted phone calls. Hell, even SIP+RTP, which regular modern calling is based on, has encryption capabilities. Of course your phone won't ever do that by default (your government wouldn't like phones they can't wiretap at all) but in theory we don't even need to drop the phone number system to get privacy back.
