Yeah, that fits with my experience and research. Those various links you, Andrew, posted were very useful. Thanks. It's hard to know what's really happening. If I might add an account of my varied experience. A few years ago, my main daily phone was a Bluboo S1 (one of the other Chinese brands, now apparently defunct). I got a Boost pre-paid SIM (which runs on Telstra network). I couldn't make phone calls. However, if I put the SIM in my then new Pinephone, it worked fine for making and receiving VoLTE phonecalls, without any adjustments to settings. I got a refund for Boost SIM on the grounds that their packaging hadn't mentioned the need for VoLTE-capable phone, my main intended use being in the Bluboo phone. But it is a data-point: That at least for some SIMs on the Telstra network, they started being VoLTE only several years ago. And that, at least for that network, the Pinephone did VoLTE. Now my setup is an original Google Pixel phone running Android 10 with a Moose Mobile SIM (and a replaced battery), and that Pinephone running Mobian with a Coles SIM. Both run off the Optus Network. .... > If you are on the Telstra network, you can check if your phone supports > VoLTE by sending an SMS: > > https://www.telstra.com.au/exchange/3gxt-3g-closure-sms .... That SMS number, "texting 3 to 3498", seems also to work on Optus. But for me, for both phones, the response is "your device is not a mobile phone"! I'm guess that the Pixel is too old and the Pinephone too weird to be in their database. The Wikipedia page for the Google Pixel says that it's VoLTE capable, and so does the page .... > More details from Telstra on older 4G phones that do work with VoLTE > > https://www.telstra.com.au/support/mobiles-devices/enable-volte-mobile-phone .... (though not for roaming). That gives me some hope, though maybe it needs some configuration, and may not be supported. One the Pinephone, when making phonecalls, I noticed that the connection showed as 4G while making phonecalls (that is, it didn't drop back to 3G). In Settings, I've since changed the "Network Mode" to "4G only", and phonecalls still work (checked again just a few minutes ago). On the Pixel, it's inconclusive: the only relevant option in Settings is "4G preferred", and the display doesn't show whether it's a 4G or 3G connection. I haven't had time to do any deeper probing. I guess the take-away from this is, "who knows?". I guess we wait and see what happens at the end of the month, and take care not to have any emergencies then. :-) The Pinephone does look promising, though, in that it seems to do VoLTE on both Telstra and Optus networks. A long delayed project of mine is to get Waydroid installed on my Pinephone, so I can shift over the few Android-only apps I use (like Signal, and Whatsapp for less enlightened relatives and friends), and continue my life. I also have a Purism Librem-5, and a Pinephone Pro, but I just don't have the time at the moment to do any serious VoLTE investigations with them. (It's a fair bit of disruption to shift SIM cards around, and I had a problem — since resolved — with the Librem-5's SIM tray jamming, making me less inclined to swapping SIMs.) If people are interested, and at some point I find out anything interesting about the Librem-5 and Pinephone Pro, I can post again here. Well, for what it's worth, those are my observations. I hope they're of some use to you. — Smiles, Les. _______________________________________________ luv-main mailing list -- [email protected] To unsubscribe send an email to [email protected]
