If you are having issues with visual voicemail not working on iPhone then here’s a few tips on how to get it working! It’s happened to me a few times whether it’s because I switched phones, changed plans or got a new sim.
- Contact o2 customer support. You can do this from your o2 phone by dialling 202, or contact them on social media at facebook, twitter or instagram and drop them a message.
- Ask them to turn on the “iData Bolt On”
- On your iPhone go to Settings > General > Transfer or Rest iPhone > Reset > Reset Network Settings
After you’ve done step 3 your phone should reboot and hopefully visual voicemail will start working.
