Not receiving calls

I haven't been able to receive calls on my Smarty number for a while now. Anyone who tries to call me goes straight to voicemail. Text messages come through several hours after they've been sent. I also usually only get notified of receiving a voicemail by text at least 3 hours after the call took place, often more.

I'm using two sim cards in my android phone, and the other works completely fine, but because that one is for a foreign number there's many things I can't do with it that require a UK number exclusively. I've tried things like resetting my network settings already, to no success. Any advice would be very much appreciated!

    Ratman​ Were you able to receive calls before and this is a recent issue, or have you recently switched to SMARTY? I suspect VoLTE isn't turned on, which is a requirement, as there is no 2G/3G network with Three, and the other networks will follow soon.

     Try these common fixes:

    • Restarting your phone, turning airplane mode on and off, and switching between 4G and 5G network modes
    • Make sure there is no call barring, forwarding or blocked numbers, and do not disturb or silent mode is disabled
    • Making sure VoLTE and Wi-Fi Calling for the SIM are enabled
    • Reinserting the SIM and inserting the SIM into the second SIM slot if your phone is dual-SIM
    • Inserting the SIM into various other phones that are VoLTE capable
    • Updating the phone to the latest updates, as well as updating all applications
    • Resetting mobile network settings
    • Confirm you have network coverage and check the network status in your area
    • Testing services while outside a building, as well as in a different area, also confirming network coverage and no outages in that area

    Ratman​ First things to check:

    Account dashboard - does it show active sim and a current Smarty plan?

    Network Status check - no local mast problems showing?

      Thanks for your response! I do indeed have an active sim and a current plan, and there are no local network problems
