VoIP service recommendations

Sorry if this was asked before but what exactly is the fate of the number that I get to use for verification for 50 cents? Given that they rent numbers for $20, I wouldn’t imagine that for 50 cents they would just never let anyone else use that number for anything else.

Let’s say I use their services for a Signal account, I would imagine that sooner or later, someone will either use that very same number for their WhatsApp account (now people who have number would confuse that person’s WA account as if it was mine) or someone will just use it for Signal and I’ll lose access to my account.

Again, sorry if this was addressed before.

Even if nobody used the number, how will you ensure access to the account without a persistent number?

We can restore signal from other mobile without number?

Whatsapp prob doesn’t have that
