    Hi

    I have a huge issue with the OnePlus 6 . I have two Bell Canada SIM one for work and one for business. Regardless what settings I did one SIM can't take the call. No matter on what slot I put the SIM card the issue is the same. If I called the work first the default it will be the work regardless the SIM personal is set us main call SIM call the personal SIM it will not take the call will go strait to the voice mail. I have 3 OnePlus 6 devices I switch the SIM between the phones on all I experience the similar issue. I upgraded from OnePlus 5T and two OnePlus 3 to three OnePlus 6. I never had these issues with the same SIM card and old phones. I will be returning one phone Oneplus 6 back because I need two SIMs working. If there is any help please.

    More details about the issue. I have 3 phones OP6 and when I registered the devices on the oneplus.com website only one got two IMEI the other show only one IMEI not two. Therefore I guess this is the issue because only one SIM works at the time. Is just a guess but make sense.

    So you are saying that you have 2 SIMs inside the SIM tray and on one SIM you are getting calls but they are not comin through, is that correct?

    Yes that is correct. I changed SIMs. when you take the tray SIM out the put the tray back both SIM are OK for the first call after that the one who was called first still work and but second goes strait to voice mail. Is extremely bad.

    Not the settings are the issue. I have the 5T and 3 and same setting like on the 6.
    Both sims are active
    Default Sim for
    Voice call : ask every time
    Messaging SIM1
    Mobile Data SIM1
    I tried all alternatives and same result.

    Yes I did this was my first option. What is fishy here is that I have 3 OP6 when I register the devices only one has 2 IMEI the two not working only one IMEI

    Contact OnePlus Customer Service. This sounds fishy.

    i did they want me to send the logs which I did. One is going back and if the issue is not resolved I will send them back and find another brand with two SIMs. Was a good run (3, 5, 5T, and 6) but I guess is over

    Never say never.
    Did you perform a factory reset as your last resort?
