Hi QinYang_1314494, 

Sorry to hear about your problem.

Does you phone support 4G calling, and is it enabled in your handset settings?

If you have two SIM slots, you can try putting the SIM in the other slot. Sometimes VOLTE doesn't work if there isn't a SIM in Slot 1.

You can check if your phone is compatible with 4G-VOLTE here.

Thanks,

YulianK

    QinYang_1314494  Not sure if this is helpful........

    https://help.kogan.com/s/article/Doesthisphoneworkwithmyprovider2  and also https://help.smarty.co.uk/en/articles/4670061-what-bandwidth-and-spectrum-is-available-on-smarty  This seems to  indicate that your phone should work in the mid band, but not in Smarty's low band maybe?

    I also found this quote (and similar repeated often) : At a high level, low-bands have greater coverage but lower speeds, mid-bands have a balance of coverage and speed, and high-bands have higher speeds but less coverage. In addition, each band presents opportunities for a service provider to balance between frequency, coverage, quality, latency, and reliability 

    Is it possible that the phone does not like the UK frequency bands? I'm assuming that yours is Australian here, so hope I'm not wasting your time.
