I upgraded from an android phone to iPhone 8 plus yesterday. I activated the iPhone online and everything went well except for I don't hear my phone rings or hear text message alerts. I am receiving calls and text messages. When a call or text message comes in, all I hear is the phone vibrates and the volume is turn up high. When I go to the settings, sounds & haptics to turn up the ringtone high. I choose a different ringtone and text tone. I click on the one I want and I hear the sound loud and clear. I don't know what else to do. Please help.
