When I click at "Cellular" from Setting it shows nothing. in General->About: Carrier: Fizz 41.0.
The SIM card works if I put it in an another iPhone. Putting Fizz SIM card from my friend it also showed "NO Service".

    Hi Anjie,
    I see that you've reached us in private and a colleague of mine has advised you to reset the network settings on your device. If you've managed to do that, you can try to search again for the Fizz network. The following FAQ may come in handy:
    If you've tested your SIM card in another phone and it worked, then it's definitely an issue with your iPhone 6. In case you'll still won't manage to get to the bottom of it, try to contact apple support and ask them to help you further.
    If there's anything else that we can do for you, feel free to reach us again in private:
    Have a nice day!
