SS7 is vulnerable to attack. However, the types off attacks on the video don’t affect Signal as it requires a pin. (Make sure you set your pin to something strong and secure)

I’ve never had a cellular provider for this reason among others. Here is NBTV’s video with some alternatives to directly having a SIM card, which I combine with MySudo to get phone numbers as well.
What’s your experience with using mysudo/voip numbers in terms of services accepting them (e.g. Google)? And socially, can you do regular calls with these numbers? Any audio delays?
