Poor call effect of the mobile phone VOLTE
1. Are you sure you have established the VOLTE conversation? The prerequisites for the VOLTE conversation are:
1) Both parties of the call enable the VOLTE function (VoLTE is enabled for both the mobile phone and SIM card).
2) Both parties' networks support this feature.
3) When the VOLTE function is enabled unilaterally, the VOLTE call cannot be established. For example, a mobile phone of the opposite party does not support VoLTE, or can make a VoLTE call, but the actual call is a common call.
2. Verify that the network signals of both parties are stable. In areas with weak signals or strong interference, intermittent call interruption or disconnection may occur, which is caused by network problems. This symptom is a normal symptom, and you should try to use it in an environment with normal signals.
