VoLTE provider support

[cartron]

has anyone figured out how to use VoLTE when roaming abroad?

It works perfectly on both my 10ii and 10iii when in my home country (France), but whenever I travel abroad, I can’t get VoLTE.

Same here. I kept getting messages from EE (Optus) in Australia telling me my area was 4G calls only, so please could I enable this feature on my phone. The 4G calling light just kept blinking forever. EE VoLTE works fine in my home country of the UK.

You could flash the old image and find out. Or upgrade the 10. The fact that it is mostly an issue between the operator man modem firmware.

Hello, I tried these steps from: Sailfish 4.4 T mobile network denied

And that resolved the “denied” status! And the phone is back on T-Mobile network.

(I tried this on Sony 10 Xperia III, after trying the SIM card on another phone; and then replaced the SIM card with a new one, and “denied” status did not change)

Sailfish 4.4 T mobile network denied

Hi All, I got network denied showing on cellular network on network searching on T mobile on Saifish 4.4 I don’t remember I had this problem on saiflish 4.3/4.2. I didn’t change my previous Data Access Point and MMS configurations. Any ideas to fix this. Thanks.

# Make sure repositories point to right version
devel-su ssu re 4.4.0.58
devel-su ssu rr adaptation-common
devel-su -p pkcon refresh
devel-su -p pkcon install ofono-ril-binder-plugin
# Reboot device
devel-su -p version --dup

Of course, update the version number in “$ devel-su ssu re 4.4.0.58” to proper one.

Thanx

I am in the US, using T-Mobile service from Red Pocket (GSMT). Following your instructions, VoLTE calling is now working. I am able to send and receive MMS. Thank you!

Would it be possible to provide what settings you do have MMS settings, and data access point settings, and other settings to have MMS work for T-Mobile on Sony 10 Xperia III, in the US?

MMS is not working with my Sony on T-Mobile service, not sending nor receiving. And I do not mind going with Red Pocket, already have a service with them.

Thanks

Third attempt I got USMobile SIM and put it in Sony. It’s been in there a few days now and I’ve never gotten anywhere but Denied. I haven’t tried it in any other phone yet.

This solution helped:

@abranson

or want to try a generic one, create a directory in the /vendor/oem/modem-config/ directory corresponding to your SIM ID and create a modem.conf file there that contains the relative path of the actual config file.

don’t get this:
i shall create a folder with S139.1 ok
then create modem.conf in it ok
but how should the content of that file look like ?
just some
…/…/firmware_mnt/image/modem_pr/mcfg/configs/generic/euro …

and if i cant find hot nor magenta in generic/euro/ what then ?

[rogerblizz]

Sure. See screenshots below from my 10 ii. Red Pocket GSMT (T-Mobile SIM).

Updated the Wiki with my testing on Vodafone Romania, for some reason I can’t send SMS with the setting on, but otherwise it’s fine - shows Registered, can call, can be called, can receive SMS.
I have an Orange Romania SIM available also, so will update when I get the chance to try it.

T-Mobile and US Mobile will register on the Xperia 10 II. Phone calls now work. SMS and MMS works.

To get MMS working use the following:

• T-Mobile
  • MMS APN
    • Protocol: Dual (Important)
    • Proxy Address: 10.188.239.145
    • MMSC: http://10.188.239.145/mms/wapenc
  • Messages App → Settings → SMS Message Center Address: “+1206313004”,145
• US Mobile
  • MMS APN
    • Protocol: Dual (Important)
    • Proxy Address: 10.188.239.145
    • MMSC: http://10.188.239.159/mms/wapenc
  • Messages App → Settings → SMS Message Center Address: “+1206313004”,145

What would be the setup for Red Pocket Mobile in the US for GSMT?

**And what directory should one create besides the two aforementioned?

Thank you,

Updated the Wiki with my testing on Orange/Yoxo Romania with the same results as Vodafone Romania - shows Registered, can call, can be called, can receive SMS, but can’t send SMS.

In both cases this was with default settings, but given that the SMS Message Center has only one address for both sending & receiving, not sure if it’s an issue on my end.

Xperia 10iii, MTS (МТС - Мобильные Теле Системы) - enable VoLTE, then ask provider enable it in my service plan (its free), and after reboot seems it work.

@flypig should we create separate bug reports for issues?

(like the one i replied to)

[flypig]

Sorry for missing your original query @thigg and thanks for flagging it up. I think creating a separate report would make sense. It may be that there’s a need to run some tests or collect logs, and having a place to discuss that is always useful.

[emva]

Have added Telia / Phonero and the 10 III over things that are OK.

And due to my use of . in stead of - in the date (Norwegian grammar) the list is now slightly easier to read (i think)

[johnflorin]

While on vacation, I gave Ooredoo Tunisia a go, but it doesn’t register, just blinks when selected (at least on default settings and on prepay). Updated the Wiki.

[stever8]

I tested my Xperia 10 iii on T-mobile in Tampa FL (USA) region and VoLTE works fine for voice and SMS. This is on SFOS 4.4.0.68.

Thank you for sharing

On my Xperia 10ii/O2 Germany VoLTE works fine for incoming calls, but for outgoing calls there is still some funny behavior: Sometimes the phone does still switch to 2G, most of the time it does not. Sometimes, there is a calling tone, most of the time there is not. Sometimes, the entire network stack crashes after calling/calling attempt, and, guess what - most of the time it does not:-)
Just my 2 cent

Can you try to collect logs after this happens?
