Followed this guide and enabled VOLTE and VoWIFI for my carrier Smartone in Hong Kong. However I noticed a bug when receiving a voice call with VOLTE on, it will prefix the caller ID with 00.

Is there any files or setting I can amend to prevent this as it prevents my spam caller app from picking up the number correctly.
[OnePlus 7 Pro Questions & Answers] Kantana:
Solved my own problem for HK carriers, use the Denmark profiles. Looks like caller ID is hard coded to that countries profile. Both Denmark and Hong Kong use 8 digit phone numbers.

If you use UK telefonica it prefixes caller ID with 00 that can cause issues for spam call apps etc.

Country: France

VOLTE = WORKING

VOWIFI = WORKING

All is working perfect, and the fact there is a Orange profil which is the only working with VOWIFI seems that Orange had already worked with Oneplus to support VOLTE.

But the profil isn't activated by default.

The other bad point for me, is like VOLTE/Oneplus are not OFFICIALY supported, the network disable VOLTE/VOWIFI after 24/48/72Hours... So need to call back the support to reactive the option ...

It seems Orange is blacklisting the device which are not 'officialy allowed' using your EMEI.

I know it was possible to change EMEI in software (hot change) with older Android 4.X 5.X ...

Could I emulate the EMEI of my old s10 in order to be whitelisted VOLTE ?

Regards,
[OnePlus 7 Pro Questions & Answers] proa_p:
I am not rooted. Just be careful when in PDC not to remove some other active profile and you're good. I tried at least 10 different profiles without a problem. The reboots between profiles are not mandatory.
[OnePlus 7 Pro Questions & Answers] thebigtross:
[MENTION=4473650]Bochdalek[/MENTION]: You can use the Orange-France-Commercial, VOWIFI is working nice.

But after few hours, the option is desactivated automaticly by servers in Orange France.

Does your VOLTE is always working in Orange Belgium ? Or you have been blocked too ?

Officialy support device by Orange: https://www.orange.be/fr/reseau/vowifi

I update the latest OnePlus kit... And manage to get to the enable volte toggle page....but the network still drop from 4g to H or 3g when ever I make a call..... Pretty sure my service provider support it as the very same SIM card works fine on iPhone except OnePlus 7pro.

Any other solution ?
[OnePlus 7 Pro Questions & Answers] thebigtross:
Please keep me updated [emoji6]

J'ai peur qu'il te désactive l'option comme moi... Le téléphone par son emei est vu comme un Op7pro.
[OnePlus 7 Pro Questions & Answers] jeffmalin:
Quand ils te l'ont désactivé , tu avais cette configuration comme la mienne, à savoir France commercial Orange?

Avant avec le OP6T et la configuration India, ça marchait nickel!
[OnePlus 7 Pro Questions & Answers] thebigtross:
La première fois qu'il me désactiver j'avais uk Telefonica.

Ensuite ils viennent de me désactiver ce matin après 24h d'activation...

Sur ton OP6 tu avais tout le temps la volte ? Pas de des activation ?

Avec le profil uk Telefonica loption a tenu 72h.

Avec le profil Orange-France-commercial l'option a tenu 24h.

Jai discute avec le Tech de Orange qui s'y connais bien. Il ma dit qu'il peut forcer l'activation de volte/vowifi mais lors ma mise à jour du serveur ça saute.

Ou alors il faut activer l'option normalement et attendre 24-48h avant activation. Sauf qu'il ne s'activera pas sur un EMEI de marque one plus...

Comment as tu procéder ??
[OnePlus 7 Pro Questions & Answers] jeffmalin:
Alors moi, comme toi j'ai commencé avec le profil UK TELEFONICA et ça a marché 72H avant qu'ils me coupe.

Hier, j'ai remplacé UK TELEFONICA par FRANCE COMMERCIAL ORANGE et les ai contacté pour l'activation et depuis maintenant presque 24 H , ca marche. Mais j'ai peur que comme toi, l'option se coupe bientôt.

Avec mon OP6T ça fonctionnait parfaitement en utilisant le profil INDIA VOLTE et j'avais tout le temps la volte. Je n'avais meme pas eu besoin de contacter Orange pour l'activation de la volte.

En 2me puce SIM , j'utilise SFR et là la Volte fonctionne tout le temps!!!

C'est juste un casse tête pour trouver à faire fonctionner ORANGE.....

Si tu trouves la solution, je suis preneur. De mon côté je te tiens informer si ils me coupent encore. Sinon j'essaierais à nouveau avec le profil INDIA VOLTE qui avait fonctionné avec mon OP6T!
[OnePlus 7 Pro Questions & Answers] thebigtross:
Merci pour ton retour man.

J'ai bien peur qu'avec orange et one plus nous soyons dans la mouise...

Appartement d'après un mec assez compétant que j'ai eu au service client. Quand il t'active la volte manuellement, l'option est effacé par un serveur qui scann le réseau. Orange repère que le numéro emei du téléphone correspond à un one plus.

One plus = pas supporté pour eux = black list = desactivation

Tout simplement!

J'ai ouvert une réclamation via le site Orange. Tiens moi au courrant stp. Je t'invite à faire pareil si ça marche pas pour toi.

Tiens moi au jus [emoji6]

PDC Issues

yoooo I have been progressing through this tutorial with success on a 7T Pro until the PDC part. When I click the 'Device' dropdown, no device is shown despite my Windows Device Manager recognising 'Qualcomm HS-USB Diagnostics 9091 (COM5)' as a Port and QPST recognising an active phone being linked to this COM5 port. This is my first foray into tweaking phones but I am pretty sure I have followed the instructions carefully thus far.

Context: Australia / Kogan provider (which runs on the Vodafone Network which supports VOLTE/VOWiFi)

[OnePlus 7 Pro Questions & Answers] Zayatoshi:
Hello everyone.

I activated the volte and the vowifi on my oneplus 8 pro, on my two SIMs, with the manipulations * # 800 # / * # 801 # ....

And the operations with the PDC software by deleting the oversea commercial profile, etc.

Everything works perfectly fine ... Except for each update of Oos.

Indeed, after the update, the Sub1 profile is deactivated and the commercial oversea profile reappears. I therefore lose the volte and vowifi on my sim 1.

I have to redo the manipulation with the PDC software and a computer after each update. Which is painful.

My question is, is it possible to make a backup without Root, of the parameters of the onepluslogkit software for example, to avoid losing the volte and vowifi on certain SIMs, following an update?

To avoid using a PC and PDC software?

Thank you in advance for your replies

Also having trouble with AT&T in USA.

Currently running Resurrection Remix 5.8.9(20200830), Magisk 20.3.

The ROM already has VoLTE VoWIFI switches/options but I cannot get the icon in statusbar. Also in "phone info" (*#*#4636#*#*) under "ims status" says not registered.

I believe AT&T only allows 'branded' devices but there must be a way to override?
[OnePlus 7 Pro Questions & Answers] jcsww:
AT&T uses the devices IMEI to determine if it was purchased from them. If it wasn't, they will block you from using VoLTE and WiFi Calling.

Hello everyone i have problem with VoLTE and WoWIFI i tried many profiles but still the same problem with every profile i tried .. i tried german vodafone , telefonica UK, commercial DT Germany , India volte vodafone, germany volte vodafone and many more but still the same problem

many times when you make a call it takes to long to make a call then the VoLTE vanishes and goes back to 3g(normal call) which takes longer than not having enabled VoLTE ,, and sometimes to the other end when someone calls me it shows them that my phone is switched off then i have to go to airplane mode turn it on wait a bit turn off airplane mode to come back so other people could call me.

also problemwith sms it takes ages to be sent when VoLTE is active

Model of the phone:OP 7 Pro GM1913

Country: Croatia

Carrier: HT HR

Settings used: as i said above curently trying with h3g_Denmark_Commercial

still the same problem

i hope someone have some solution to this :)

no no I am on stable not on beta

curent version of my os is 10.0.10.GM21BA

to replicate the problem restart the phone and try to send an sms the sms says "sending" and when you try to make the first call no matter which number it takes long until it removes from volte to 3g to make the call (which is the period double when normal without VoLTE)
[OnePlus 7 Pro Questions & Answers] dilruk:
Sorry mate. Can't help in that case. Works for me without any issue.
