A smartphone isnt required, only a telephone number for authentification.
- fauigerzigerk 9y agoThe problem is that you need to own that same phone number permanently. Phone numbers are tied to exactly one SIM card, which is tied to exactly one telco in one country. Too many ties. Threema doesn't require a phone number but it's not free.
- dmytroi 9y agoDepends on a country, in Sweden you can move your mobile number to any telco, and anyone can look up your number and your home address using something like [0]. But yes, it is still tied to a country. - [0] https://hitta.se https://hitta.se
- fauigerzigerk 9y agoYes, what I meant to say is that the SIM card is tied to exactly one telco at any particular time. It's also tied to one device at a time. Perhaps one of the virtual SIM card offerings would work with Signal though. I'm juggling too many SIM cards and phones already. I don't want any new dependencies that complicate matters further.
- LamaOfRuin 9y agoYou only need the sim card active to activate your signal with that number. After that you don't have to be connected to a cell network at all.
- fauigerzigerk 9y agoBut I still need to keep the SIM card active or I could never switch phones (or reinstall the phone OS) without losing my Signal identity. I cannot ever let go of the phone number I used to activate Signal. In practice, that means I need to keep paying for a phone tariff I may no longer want.
- LamaOfRuin 9y agoTrue. I was assuming most people have at least one phone number they want to keep long term (even if it's not always active with their cell). Note though that signal will also work fine with non-traditional services that provide free or much cheaper phone numbers like google voice (US), skype, or twilio. It is true though that you do need to maintain a phone number. That is one of the trade-offs they made to allow it to actually be usable. I have not seen a better solution for encrypted communication yet.
- fauigerzigerk 9y agoHow does the phone number tie-in make it usable? Phone numbers and SIM cards are about the most user hostile thing I can possibly think of. What's wrong with the way Threema does it for instance, which is essentially to bind the identity to a key pair that you can back up?
- LamaOfRuin 9y agoThreema appears to optionally do the exact same thing. Signal eschews the flexibility to ensure more universal usability by being able to assume that anyone who uses signal can be associated with their phone number. An assumption that holds for the vast vast majority of potential users.
- fauigerzigerk 9y agoI don't see how making phone numbers mandatory makes Signal easier to use at all. There must be another reason for this restriction. Some say it's for spam protection.
- wyclif 9y agoSignal will work with Google Voice, but as far as I can tell you still need a smartphone to use it. Without that, you can't even set up an account because you need to scan an OCR code first.
- jhasse 9y agoNo, you can change the number associated with your Telegram account.
- fauigerzigerk 9y agoI was talking about Signal. Sorry I didn't make that clear. The phone number is your identity. Changing it means reregistering with a different number. [Edit] And I think it's essentially the same with WhatsApp, only they now make it a less manual process.
- jhasse 9y agoAh, I should have mentioned that I was talking about Telegram in my original comment, too. Can't edit it anymore :/
- Vinnl 9y agoYou do need one to set it up, right? I had to scan a QR code displayed on my desktop with my phone. (I could continue to use the desktop app while my phone was being repaired, though, which was great.)
- jhasse 9y agoNo, you can do the complete setup with the Telegram desktop app, but you need a device which can receive SMS or a phone call.
- notzorbo3 9y ago> A smartphone isnt required It is for Whatsapp. Not only for sign-up, but actually all communication on the web version goes through the app running on your phone. The web "session" times out constantly, so I'd have to re-pair it with my phone all the time. If I still decided to use whatsapp.
- exikyut 9y ago> [A]ctually all communication on the web version goes through the app running on your phone. How on earth does that work? Say my phone's on data, my laptop's on my home wifi with NAT. How does Whatsapp on the web reach my phone?
- tiagoespinha 9y agoYour phone connects to WhatsApp's servers. So does your laptop. The bridging is likely done server-side. I assume this is done because WhatsApp is (probably) using end-to-end encryption, so everything must be ran by your phone (which is the only place where your private key is stored) in order to encrypt the messages.
- JosephRedfern 9y agoIt works impressively well, though -- I use it far more than I do the mobile client directly.
- BenjiWiebe 9y agoTo be really pedantic; a smartphone is not required for WhatsApp. You can activate a Google voice number with a landline, then use your Google voice number to activate WhatsApp running in BlueStacks or your emulator of choice. Source: I did this for a few months. I'm not quite sure why...
- philtar 9y agoA smartphone OS is required for whatsapp
- ossguy 9y agoIn these cases you could use a https://jmp.chat/ https://jmp.chat/ phone number. No smartphone is required for JMP, only an XMPP client (see https://news.ycombinator.com/item?id=16352711 https://news.ycombinator.com/item?id=16352711 for some client options).
- jhasse 9y agoA smartphone isn't required for Telegram either.
- TheKarateKid 9y agoIncorrect. Whatsapp refuses to open on my iPad and isn't even available in the App Store. The only reason it got on there was a glitch in Apple's app sync which must've auto-downloaded it since I have it on my iPhone.
- jhasse 9y agoSorry, I was talking about Telegram. Should have made that more clear.
