I am not getting consistent mobile network, it often switches from 4g to 3g to 2g and vice versa. I am on Airtel India. This issue never occurred on the Galaxy S7. Please let me know if there is a fix or known issue.
I'm struggling with service issues too. I'm in the US with T-Mobile (Mint) and just transferred my SIM card over to the Z6. If I'm outside the house I can call just fine but inside I can't make or receive calls. I had to pop the SIM back in my Pixel XL to make a call Sunday. Anything I can do to improve this? Some sort of carrier provisioning need done?
T-mobile offers a signal booster that you can install in your home to boost 4G data signals. Perhaps that could work for your use case. https://support.t-mobile.com/docs/DOC-14947
