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.

    Silent.link is also worth considering. I think it also works for people in the EU.

    Haven't used it [silent.link] myself. All I know is that all (or some) plans they offer include only incomming-calls, not outgoing. But good point you make about delays. That's important. Haven't thought about that myself.

    I'm not too versed in it myself yet. You were asking about these services in general, right? Since you wrote "voip numbers". I'll keep tabs on your other comment then
