Google Pixel 8 Pro (Custom Rom) IMS provisioning required - 4G/WiFi calling does not work

Hello everyone,

I started using a Google Pixel 8 Pro with a T-Mobile NL prepaid SIM card about a year ago.
The phone is mainly used in Germany. Since commissioning, neither VoLTE/4G Calling nor Wifi Calling has worked in NL or DE.

Phone number, SIM card details, phone details can be given to an authorized employee.

What has already been tried:
1.Several chargeable calls to the hotline asking for troubleshooting.
-in NL
-in DE/GER
2. reset the network settings in the SIM settings
-in NL
-in DE/GER
3. reset the network and WLAN settings in the phone settings app
-in NL
-in DE/GER
4.manual APN configuration
-in NL
-in DE/GER

The phone has a custom rom installed that is based on Google AOSP 15.
Years ago, Deutsche Telekom had to provision a Google Pixel with the same operating system in a similar case. Support also performed a Visitor Location Register (VLR) reset for the SIM card or phone at the time.

I would be grateful if a technician with the appropriate authority and expertise would get in touch to carry out provisioning so that I can finally use 4G calling. The hotline always assumes that the device or the SIM has a problem and never knows what to do. In addition, a credit note of 10-15 euros would be appreciated to cover the costs of the unsuccessful telephone calls to the hotline.

Kind regards

Hi, welcome to our Community, and nice choice on the Google Pixel 8 Pro! I'm sorry for the late reply. Your topic has been wrongly marked as spam, so I just found your topic just now. Have you had any contact with my colleagues from customer service yet? Or do you still have an issue with calling in the Netherlands and Germany? If so, please fill in the following information in your profile: full name, 06-number, date of birth, zip code + house number and the last 4 digits of your IBAN. I'm happy to look into it for you, and forward a case to my technical colleagues if necessary! đŸ˜Š

Hi ​@f864t0spi9l0r99f72ms ,

Prepaid cards only support calling via 2G (abroad) + 3G (abroad and NL).  It does not support Volte (yet).

So, if you want to use it now, you can apply for a small regular postpaid subscription and Volte will be avaliable.
