If somebody calls me, I can hear them but they cannot hear me. However when u call them back, they can now hear me.
I spoke to Vodafone who told me to unregister with them, register with another provider, turn device off, and when I restart the device, it will automatically switch back to Vodafone and it will be rectified.
I did this and no chsnge, has anyone any idea how I can fix this? (If it can be fixed)
