Since ID Mobile introduced VoLTE my Cubot KingKong Mini2 mobilephone has gone silent.
I only accept text messages, I can't talk. According to the manufacturer's website:
https://www.cubot.net/phones/Kingkong-mini2-pro-specs/82
this phone has the following types of calls:
- 4G FDD-LTE: Band: B1/ 3/ 7/ 8/ 19/ 20
- 3G WCDMA: 900 / 2100 MHZ
- 2G GSM: 850 / 900 / 1800 / 1900 MHz
The settings on the phone are:
mobile data - yes
Roaming yes
4G Calling yes
Wi-Fi Calling On
4G prefered
Can anything be done to make this phone work normally ? For example, maybe it would help to replace the SIM card also ID Mobile, but with VoLTE option ? Maybe some additional software or driver ? Please help.
