dicer 36 Posted August 10, 2020 Share Posted August 10, 2020 Did the same as @DieBruineand can also confirm that VoLTE works for me. I'm on o2 Germany. Wifi calling also works. Both on lineage. No icons are being displayed for either though. There is a Lineage pull request that is adding those icons: https://review.lineageos.org/c/LineageOS/android_frameworks_base/+/279554 2 Quote Link to post Share on other sites
D1ggs 141 Posted August 22, 2020 Share Posted August 22, 2020 (edited) Zero issues with my pro 1 on versions volte. Once it was set it hasn't come undone. Been going on about 3 months now without issue. This has been with stock and updated as fixes are made available. Edited August 22, 2020 by D1ggs 2 Quote Link to post Share on other sites
fashion_m 5 Posted November 9, 2020 Share Posted November 9, 2020 (edited) Hi, I use Fxtec Pro1 with the Bulgarian mobile operator Vivacom. "VoLTE provisioned" switch is grayed-out and turned off. I called the support and they told me that VoLTE is enabled for a whitelisted set of popular phones only. The guy sent a message to the technical team about my phone, but it's not guaranteed that Pro1 will be whitelisted neither I'll be contacted at all. I am in areas of bad coverage and the phone frequently switches from 4G to 3G/2G and my internet becomes slow, so I explicitly set network mode to LTE, because weak LTE signal delivers faster internet than 3G with better signal. The bad thing is that I cannot make and receive calls, and I do not even get SMS about missed call. The calling party hears "busy" signal.

Very annoying, just to ask are you running the latest version of stock? First i've heard of a GSM carrier whitelisting popular phones for VOLTE. If you are, I would suggest getting root and trying to enable VOLTE using the various patches out there. Quote Link to post Share on other sites
