iOS visual voicemail malfunction
I’m posting here hoping someone will be able to help me. I encounter a strange behavior with visual voicemail on my iPhone.
I’m using an iPhone 12 Pro Max on the latest iOS version (14.5.1) with two SIM cards:
An Orange France eSIM
A Bouygues Telecom physical SIM
Both carrier settings versions are on 46.0
When I get a voicemail on the physical SIM card everything is working as expected, but when I get one on the eSIM, as long as NextDNS is enabled I won’t receive the voicemail notification, which is pretty annoying.
I was able to reproduce the same malfunction on two different iPhones with the same configuration. Nothing seems to be blocked in the logs so I can’t understand what’s wrong, especially since everything else (like VoLTE, WiFi Calling etc.) is working great.
Thanks you in advance
One of it's thread responses mentions telephony domain whitelisting & opening/forwarding specific ports. However that thread is in the context of American wireless carriers so you might have to research & modify the concept for the specific UK/France wireless carrier(s) you're using
@rems I just noticed the same issue on my iPhone 12 when I switched to an eSIM (Sosh). Did you find a solution to that problem?
I actually discovered something interesting. I had installed the NextDNS DNS profile on iOS. As soon as I removed it, my messages appeared on the voicemail. Even if I am behind a router configured to use NextDNS. So I suspect NextDNS is not blocking anything it should not. The issue seems to come from iOS and the way it uses DNS configuration. Could someone confirm ?
Also noticed I can't send iMessage when on 4G with NextDNS profile installed. On Wifi everything is fine.
Could you try with the same profile you are currently using but excluding the domain "dav.orange.fr" (you can exclude specific domains on https://apple.nextdns.io, under Advanced), and tell us if that solves the issue?
Hi. Same issue with Fizz Mobile in Quebec. Please, help us NextDNS ;-)
Exactly the same issue with T-Mobile.
allow this for t-mobile
e7.vvm.mstore.msg.t-mobile.com *.e6.vvm.mstore.msg.t-mobile.com *.e4.vvm.mstore.msg.t-mobile.com *.e3.vvm.mstore.msg.t-mobile.com *.e2.vvm.mstore.msg.t-mobile.com *.e1.vvm.mstore.msg.t-mobile.com *.e.vvm.mstore.msg.t-mobile.com *.e5.vvm.mstore.msg.t-mobile.com *.t-mobile.com *.msg.t-mobile.com *.mstore.msg.t-mobile.com *.vvm.mstore.msg.t-mobile.com
I'm sorry to hear that you're experiencing issues with your visual voicemail on your iPhone. Based on the information you've provided, it seems that NextDNS may be causing the issue with the eSIM voicemail notifications not coming through.
NextDNS is a DNS filtering service that can block certain websites or services based on user-defined rules. It's possible that NextDNS is blocking the notification for eSIM voicemail, which is why you're not receiving the notification.
To troubleshoot the issue, you could try disabling NextDNS temporarily and see if the eSIM voicemail notifications come through. If they do, then it's likely that NextDNS is the culprit. You can then try adjusting the NextDNS rules to allow the voicemail notification to come through.
If disabling NextDNS doesn't resolve the issue, you could also try resetting your network settings on your iPhone. This will reset your Wi-Fi, cellular, and Bluetooth settings to their default values, and may help resolve any network-related issues that could be causing the problem.
To reset your network settings on your iPhone, go to Settings > General > Reset > Reset Network Settings. You'll need to enter your device passcode to confirm the reset.
I hope this helps resolve the issue you're experiencing with your eSIM voicemail notifications. If you continue to experience problems, you may want to contact your carrier's support team for further assistance.
