Hi all, a quick question from someone who has ignored VoLTE until now:
My setup until now has been:
Dual SIM phone
SIM1: Voice, prefer 2G
SIM2: Data, use for mobile data, prefer 4G (or 3G)
The second sim has a different Plan, unlimited and cheaper mobile data but more expensive calling (and nobody knows that phone number).
Now my provider has also announced the death of 3G, and sent me a text to enable VoLTE/4G.
Questions:
VoLTE only works while Mobile Data is enabled, correct?
VoLTE under SailfishOS always chooses the connection of the SIM that is set to mobile data, correct?
Therefore, it is not possible to keep my current setup pf phone service on one SIM, data on the other?
3.1 ā¦ or is ist possible to have SIM1 call via VoLTE over the data connection of SIM2?
What about Wifi? If VoLTE is enabled and working, what happens if Wifi is switched on, and mobile data off? Will I still be reachable by phone?
Focus more on my first part of the answer. I missed that 4. too conflated data and VoLTE.
Assuming Jolla and Android doesnāt share your confusion, the two should be unrelated - just like old-style calls.
Volte is only necessary, if you need to use data during calls (with the same sim-card). If you use your second sim for data and your primary for calls, the modem have to switch anyway between them, or is it possible to use them at the same time? With your setup, there should be no difference at allā¦
For completeness: i can call via VoLTE when i have āInternetā turned off. This is actually a much better name for the setting commonly referred to as āMobile Dataā.
I of course cannot guarantee your operator doesnāt double-charge you for data consumed for the dedicated IMS(VoLTE) access point. Though that would be really evil, and possibly illegal.
I also cannot help to wonder how much this faffing would be worth to me. My plan gets me 14 GB (much more than i use) and practically unlimited everything else for like ā¬15. It would basically have to be free for me to even consider dual-simā¦ but i guess iām not the target audience.
Some if it is inertia, and kinda if-it-aint-broke.
Some of it is rhe fact that the contract (plan) for SIM1 is an ancient one with some benefits that arenāt offered with current contracts, and it would be unwise to change that.
But it seems it has become ābrokeā now, so Iām trying to find a good way forward.
Iām a bit confused. Which provider? Sim2 is dropping 3G? If sim 1, are they also dropping 4G?
I noticed that just keeping my sim1 on 4G is a savings over wifi
Iāve also been ignoring this since all my plans are 4g+, so, who cares. I thought. I have a really old setup where I have a 3 sim contract with one sim being āonlyā data, one 4g+ but no sms support and one having all + sms. But, since thatās confusing, I use those cards in different phones Now, that is a sweet contract (for so many sims ++) but mix it with the old smartwatch cards (donāt ask) I have at really low monthly rates and the sim madness is out of control.
I have no idea if 3G is dead. But 4G seems to work
EDIT: PS. someone call me to see if I can be reached. I was wondering why nobody calls me.
Hutchkinson/Orange/Drei/One (it has had many names over the years) in Austria. Shutdown of the 3G network is in progress. At the moment, itās working okay.
Doesnāt answer the question. If you have 4G(+) why would you need to enable Volte?. And then Iād look at the contract and say, hey, you sold me 4G. Not volte. But I donāt understand exactly whoās who in the zoo. All I know is that my providers (o2 and vodafone) both sold me 3/4g with no mention (well, didnāt exist at the time) of Volte and I believe 3G is gone here too.
This whole telecoms trying to get a free ride out of other peoples wifi networks makes me furious.
Dear Fellowsedit: Sailors edit: friends, I always thought that a Sailfish phone, that is not VoLTE capable, switches to 2G when making phone calls and back to 4G when finished. So I donāt understand whatās the problem if 3G is turned off, as long as 2G still exists.
No; sailors are the Jolla employees. The community has no name.
The phone switches to what the network tells it to. This should of course be the last remaining, preferably highest, technology out of 2G and 3G for a well-configured network with full coverage overlap. But if they never integrated/planned fallback to 2G properly, maybe they donāt want to faff with that for just a year or three and a few 100 users.
Here, 2G was disabled for phone and small IOT users 5 years ago. It was kept on for metering (power, water etc) only. The modem was swapped out of my power meter this week for a 4G one. So the 2G network will probably be completely removed in a year or two.
The big problem is that a phone is only able to use VoLTE and Voip if the manufacturer has put settings for the network in the phone. Even then, operator/network changes can break it.
Sony did not sell the X10 III here, and there is no way to make it do volte on any of the networks in the country.
If you bring your Sony here, it wonāt be able to make a voice call once 3G is shut off.
Is the Sailfish phone still usable as data device or does the network operator deny all connections as soon as 2G/3G is no more available and a phone is not compatible to run VoLTE?
That depends on the network. As you may have seen in other threads, certain silly US operators kick the devices off. There is no technical reason to need/want to do thatā¦ but there may be regulatory requirements to offer emergency calls to devices on the network, so no service at all is a way to get around that.
