I dont see how this is something they could implement. Phone numbers cost for a carrier to register and to verify that it's not already and exiting number because if it is... then you're just sending spam to some poor soul's phone.

That said as long as you're signing up for things that require a phone number but aren't actually going to verifty it is a real number or call/text you for authentication, the American strategy since the 1980s has been to use your local area code followed by 867-5309 (from the song).

This would be amazing. A phone number is much more difficult to change than an email. When I didn't have Proton I had like 10 different email addresses, and I could always make a new one, so there are ways to get your own homemade "aliases", but when it comes to phone numbers it is a lot more complicated to get them. It may be costly to Proton, but I would gladly pay a reasonable price for each alias if that is what is needed for this to become a reality.

Would love this!

Hello everyone,

One of the reasons I switched to Proton is because of email alias. And as I now take my privacy serioulsy, I can't stop thinking about the issues I have sharing my personal phone number: spaming, privacy, etc... some companies are able to make it, please Proton, enable this feature.
I would not mind paying a few more dollars to get this essential feature.

Thank you.

This should be merged with these two other feature requests (since they are all basically the same thing):

Lots of Proton users want alias for phone numbers similar to what www.cloaked.com has.

This feature would be great and important to have, as many services require a phone number.
I think it would be unrealistic for it to work exactly like an email alias that can also be used to send messages, but it would be great if I could hide my phone number in order to receive the one-time code for the service.

would be a great feature, but expensive too, they have to create a new number every tme and send the code to you

I vote for unlimited phone aliases!

Could be an add on cost, wouldn't mind paying for each new alias. This is far more critical than email aliases, IMO.

i would actually consider paying a little extra for this

They're not going to implement this ever. Nobody will because it costs them money every text message/phone call.

I know this is probably quite difficult to implement, but yes I would love this so much. Throwaway phone numbers which forward to my own would be awesome.
