    The phone indicates it has network reception but it is not receiving any calls, callers immediately go to voicemail. After a while a message comes in that there is a missed call with or without voice mail message. Making the call to voicemail takes a lot of time as if the phone has no network connection.
    Turning off-on the phone restores the network connection but after 1-2 hours the phone is not receiving any phone calls again. So the same happens again, receiving text message of a missed call.
    This problem is occuring on SIM 1 and SIM 2, both are with the same provider and indicate the same good level of reception on the screen of the phone.
    Signal strength is OK as previous phones didn't have this issue, nor have other phone users from the same provider this issue so it is One+ Nord related.
    Mobile data is on SIM 2.

    I have the same problem one or twice a week, only one sim.
    Sometimes switching airplane mode on/off will help.

    Same here. On phone there is no signs of network problems, but phone is unable to receive call. Only one SIM.

    I have the same issue. 4G data is working but no calls/sms can be received or called. "cannot reach network" message appears and drops call. Have reset apn, checked settings with other phone with same sim, reset network setting... nothing changed. Are there any updates on that issue? Thanks in advance.
