But I have to admit, I’m a bit shocked with how many people seem to still be making/receiving actual voice calls. Is this still something that people under 68 would do these days?
I mean if you already pay for a service which includes voice calls why would you then want to go pay for another service (sip) to do…voice calls?
two thirds of this thread are people wondering why anyone wants or could ever want to continue to have a phone that can phone. a couple points to note, please forgive the very slight saltiness:
I’m really sorry, I mentioned a possible work around for people who may either be left without a service or feel forced to abandon SFOS altogether. Will not happen again, I promise 
I will rather bemoan the fact that VoLTE is not available on the platform and blame Jolla for not putting their scarce resources into an issue most of their customers don’t have to deal with for the foreseeable future.
Data-only SIM cards do still exist.
I didn’t want do say I’ve found the optimal solution to your woes, I just wanted to stress that a possible work around may be available for someone who would otherwise see abandoning the platform as the only other possible alternative.
haha, you know i dont mean just suggesting sip. your app looks great, and its what i intend to use if i get closed in.
i mean all the comments that say “who uses phones anymore?”, or “mobian+pinephone have volte, so…” or “germany has 2g still” or “only the USA is getting rid of 2G” or the hundreds of people commenting something like “LTE works just fine, everyone on this thread must be crazy and i am the only sane one”
also, most Jolla customers are only a LITTLE screwed by not having VoLTE. the rest of us are massively screwed.
but essentially no one is unaffected by this missing feature.
Sure, but most people don’t have them in a PHONE (you know the thing that was designed to make calls)
I just wanted to stress that a possible work around may be available for someone who would otherwise see abandoning the platform
Sure. But if it comes to that I’ll probably leave Jolla/SFOS. Volte is literally the future for the cellular networks of the world and honestly Jolla is being very shortsighted with it. It kinda reminds me of the n900 and mms which arguably was more a “US thing”
The point I don’t get is: if 2G is cutted down, how they want to do some emergency calls?
As I know, emergency calls are also possible via VoLTE but at the moment of course made via 2G. Or am I wrong?
This also should screw Jolla customers up, shouldn’t it?
yes, afaik, emergency calls will not be possible on SFOS after 2g and 3g shutdown
Removable SIM cards do exist. 
Means you can port the number away to a SIP provider of your choice, throw your current SIM card in the bin and install a new data SIM.
This has saved me probably thousands of $ in roaming charges over the years.
Does not mean it must be the prefect solution for you - I just thought there may be people around in this thread who are serious about SFOS and would like to keep their phones past the VoLTE deadline.
Please don’t see it as criticism or something. I’m not against VoLTE and would even pay Jolla a reasonable amount for this feature if I had to.
You may also have completely different priorities and this is perfectly fine.
I just wanted to make clear that the world is not necessarily about to end after the demise of 2/3G
We are not their core market and I guess no amount of moaning will change that. 
Maybe they will first shut down only 3G to get a lot of frequencies free for new 4G + 5G base stations. 2G has a lot of benefits regarding range and reliability.
The idea is all calls go through volte. Phones without won’t be on any network
I agree, we aren’t. They will lose their core market though if they don’t get on it.
My whole point, while I was a bit salty, was the implications that “why on earth wouldn’t you use sip,” and “why on earth wouldn’t you have a data only sim in a phone.”
I do believe/hope you were at least a bit tongue in cheek with those. I absolutely concede and agree they are partial solutions.
As far as roaming, I always used FB messenger for calls while in other countries, although both tmobile and Google fi have been very good to me with calls overseas as well.
I would love to stay with Sailfish, just like I wanted to stay with the n900 (even lost money on the neo900 that never existed) but if I can’t use a phone as a phone…
Most likely I would try to daily the painphone errr pinephone which has volte. UT has been making great progress on anbox as well (while likely not polished like AD it’s an alternative…although AD has its own issues).
Still I have a few years before it becomes a huge issue for me.
If you read this: Beeline switches off 3G network on 2,100 MHz band in Moscow - Telecompaper Jolla has all interests in getting VoLTE working as fast as possible. As Russia wanted to switch the whole administration from Android to SFOS, and if the biggest customer cannot phone, SFOS looses its basis of existence. Its also a bad advertising, if you regularly bring out new OS versions for newer phones, that the user will have to install himself, but with this step, he will convert his phone from VoLTE capable to non capable. So i am quite sure we will see VoLTE coming, the question is just when, and how long we will still have to wait. Hopefully not that long that many sailors leave the ship…
Your mean in Russia? They will certainly implement VoLTE when Ростелеко́м say they should…
Yes, partial solutions at best. Coming with a whole host of drawbacks and additional costs if you don’t have the infrastructure already in place and not exactly easy to set up. But a possible life line for those who may get kicked out of the network otherwise.
N900 had SIP built in from the start. I even remember using it quite extensively on Symbian before that. Sailfish was a large step back when it comes to SIP when, for whatever reason, they decided not to implement it at all.
@Peterleinchen you are right. But at the time you didn’t needed VoLTE. Now the situation is different. And like i say, if their biggest customer wants it, they will get it. Also new members will perhaps just join with VOLTE which has been established as a standard by other mobile OSes and manufacturers…
I’m not sure why you keep harping on sip.
Depending on how much of the signalling the modem will actually handle there is a certain chance Jolla will have to also implement SIP, as one of the transport protocols used in VoLTE is exactly that.
But I will shut up about it now, promise 
Sony’s provided ril library contains VoLTE stack, And RILD has VoLTE, but Ofono lacks support telling RILD to register to IMS and make calls via IMS. Ofono needs same functionality that has in RILJ (java part of Android Ril stack).
