That's really great. This will improve users privacy

Are there any plans to add Proton VoIp for Paid Users?

If in the future you will ever treat also phone numbers then I'll immediately switch.
I live in Europe and in my country phone companies keep sharing data everywhere to any serious or even malicious company to propose fraudulent contracts of any sort.
The supposedly more serious phone company, to actually really deny the share of your personal data, requires a number of (untold) steps: you have to deactivate consensus from your dashboard, but then you'll discover it's not sufficient so you have to call operators to deactivate other things they only have access to, but then you discover is again not sufficient so you have to contact their privacy department and ask for other operations they only have access to, and then it's still not sufficient and you have to request them instructions to apply the "right to oblivion".
This is just crazy and 4 layers away from any consensual usage. Meanwhile I receive fraudulent calls where they know full name, home address, job, etc (and also data that ONLY the phone operator can have, that proves to be the source).

I really hope there will be, one day, a consensual phone operator that cares about privacy just in the way the user expects it... I mean, not even hiding from police investigation or something, but only treating personal data in a consensual way with what the client wants (and so, not sharing with other commercial entities if the client says so).

Or if not Protonmail, maybe a service suggested/endorsed by Protonmail...

Banking services and online services seem to be requiring SMS in order to use their services. Without it, you cannot use their services. I have been without a mobile phone for 5 yrs, and twitter locked me out for security and I've been unable to get back into my twitter account because it demands I provide an SMS phone number.

Other sites are like this, especially financial ones. This means that AT&T is really insinuated into all these services, and THAT means heavy use of SMS means that the NSA for some reason needs access to your banking and social media also. Not sure why. (AT&T is the private face of the NSA, and AT&T fundamentally controls all of SMS)

I'd like an SMS-compatible service for Protonmail, to act as a 2 factor authentication in order to make these services that only offer SMS as a means to get into your financial and social media.

I know that protonmail is not a VOIP company, but an email company. However, I live in a cabin and have no mobile phone and I don't want a mobile phone, because I am so remote there are no cellphone towers that are available within 5 mi of my cabin. So I have to use VOIP as my landline, using a very minimal broadband point-to-point long distance microwave (wifi) solution which is sufficient.

I notice that banking and other online services are absolutely tonedeaf to rural people, and more people are moving to rural from cities because of covid. They are in for a HUGE surprise: internet is still spotty and difficult in 2021. So is cell coverage.

This SMS reliance effectively means that if you can't get to a cell tower then you cannot use these services, because you cannot use 2 factor authentication via SMS.

This is a problem that has effectively 'frozen out' rural people from crytpocurrency banks like coinbase, online only banks like ally.com, and twitter, facebook, google and other services that heavily rely on SMS

This is a problem. I kind of hate SMS because of this, but Proton could come up with a solution for those of us that are frozen out.

I am guessing its far more than you could realize, but maybe research it if it sounds like a service you'd want to offer.

All you would really need is secure SIP provider that could handle SMS and then could then encrypt it in an envelope that would hide all disambiguation details, the content AND the phone number; and of course a database where the relationship between the sms number and the email address is stored

You could even have the SMS number stored in the users protonmail account and does a "lookup" of any sms messages in a database using the hash of the encrypted phone number to match the hashed number in the database, and make it user initiated

So if someone is waiting for an SMS message, they can go and click a button "look for messages" and then in their application they can have the application send the SMS 2 factor message

and for 5-10 minutes after the user presses the button, it will look for any SMS messages in the database. This 'user initiated' process means that proton won't have to use so much resource to constantly poll for sms messages. SMS messages just acts like a shared inbox, where the hash of people's sms phone number acts like a "post office box for sms"

2018? nothing yet?

I am an online English language teacher and teach people from all over the world, most of my students are from Russian speaking countries, but I also have some in China and Iran. Sometimes these students nievely say things during conversation practice that might not be considered politically correct in their countries. I am currently using Skype, and although it is a good system, I understand that it could be monitored and would be more comfortable with a similar system, but with end-to-end encryption.

would be a great addition to the proton suite of servces

Great idea, from the people that build in security

great Idea, I second that

I agree, an alternative to Burner App, Sideline, or Google Voice would be great. Those apps all work well, but having ProtonMail's encryption and privacy, privacy we know and trust, would be something i would use personally, but also on a corporate level.

With the increased requirement to use phone numbers online, which give anyone with that phone number the keys to the castle, this would be a huge gain for the overall privacy of the protonmail user.

hello! I would really appreciate if you incorporated the feature of a Virtual mobile number inside proton mail, and better still if you could subscribe to multiple numbers from a list of countries, you need mobil. numbers for all sorts of registrations and verifications online and now you have to rely on outside systems. if the could be used for two-way-ommuncation with sms sent FROM protomail also it would be perfect. I want to recive all sms inside protmail. I would be willing to pay 100 euros/year for one number and maybe 50 euros/year for additional numbers.
my best regards Jonas

I would really like to see Proton implement a SMS/MMS enabled voice service (similar to Google Voice) that would allow Proton Paid users the ability to also get a phone number in their region and have the opportunity to make voice calls, txt's, etc.

This would be a great service... trying to completely disconnect from google, and the sooner the better. Softphone and/or adapter to connect standard telephone.

I`m suggest you ProtonVoice - voip dialer with zrtp and pgp support, open source.

Do you have voip ?
How can you use it ?

Signal has both voice and video calling now.

...anyone have experience/info with Silent Circle silentphone...?

Still looking... agree that ongoing events underscore the need for the encrypted voice company to be outside of the USA.

@Laurent: What is wrong with Signal? For example that the Signal requires tons of access rights when being installed on the phone including your phone number, email, etc. (so far from anonymous). Signal can't be installed on anything else than smartphone - i.e. no way to install it on tablet. Last but not least it's American company. Given the current legislative, you have to believe/hope, that Signal is secure. Yes, it's open source, but current hack of WhatsApp, which is using the Signal protocol, shows that it's not 100% secure. If the Signal is forced to cooperate with secret services, they can never tell you without breaking the law. They could only close as Lavabit did.

Try Jitsi ! jitsi.org

It comes with a free xmpp/Jabber account and let you make encrypted voice and video calls. (secured by SRTP and ZRTP)

It is opensource, end-to-end encrypted and you can chose the ciphers AES128,256 or Twofish 128 or 256.
