========================================
My phone motherboard is replaced twice. I know this is a known issue for this model phone and Asus got no fix for this.
My problem now is with the mobile network. It always shows No Mobile Network. Im facing this issue even before the phone motherboard is changed. It works fine in a different phone. I even have replaced the SIM card but still the same. It happens frequently and most of the time my phone network is unavailable. I can't make calls and also receive calls. I have tried reset the network settings by turning On the Airplane mode and turn it off but still no luck (even i know this fix won't work). The network will come again for awhile then it goes back with no network. Is this also another known issue for this model or is there any network setting that i need check/change?
Note, the phone firmware is up-to-date.
