You can change your iPhone ringer to increase the volume and improve your ability to hear your iPhone in public, noisy places. If you set the ringer to the maximum volume setting and it still isn’t loud enough, you may need to change the ringtone for your iPhone. Some ringtones are louder and provider better penetration in noisy conditions. Generally, higher-pitched ringtones are more audible than lower, deep-sounding ring tones. You can experiment with different sounds until you find a ringer that works for you. Tips Warnings Writer Bio
