What should I do if there is something wrong with vvm.mail.wo.cn Apple's mobile phone?

Vvm is a thing with built-in voice, that is, Unicom Wo, which can be solved by testing and turning off 4GVoLTE. The specific reason should be the problem of Unicom network, which leads to the loading of voice server.

For mobile users only, update 9.2(ipcc23. 1) has built-in voice mail. After the trial, you can call the voice mail if you don't answer the phone, and you can't call the voice mail if you can't get through when you turn off the phone. The prompt is the original voice "the number you dialed is power off", and there is no prompt in the login message, let alone the SMS prompt.

Later, a friend who specializes in developing and testing VVM in a mobile company helped me find the root of the problem. VOLTE (high definition voice) and (off) call forwarding conflict. Call 10086 to shut down and return to normal.

There are many problems in updating 12 1 1:

1, unable to open mailbox, saving password.

Voice mail can only be set and answered with mobile data (mobile data can also be turned on at the same time under WIFI, but it must be data traffic. As for the unavoidable traffic, it depends on the later stage of mobile)

If the password has been saved, you can try to restart it when the network is good. After all, there are many people who have opened this service recently, and the server is busy. Try a few more times in the future.

2. If the call forwarding fails, it will prompt that there is an empty number and it has been turned off. ...

First, consider whether to turn on the VOLTE (High Definition Voice) service. You can call 10086 to close the customer service inquiry, and then reset the call forwarding +86 12599. After successful setup and testing, you can restart VOLTE as needed.

If it is not turned on, but the call forwarding fails, please check the phone settings-call forwarding-and set the call forwarding condition to +86 12599 as needed (please don't forget the+sign, voice mail unified service number).

3. Voice mail and "and messages"

The two are the same, one is built-in and the other is APP. The latter has more personalized settings and can also set SMS prompts.

After testing, the speed of message and SMS reminder is faster than VVM, and the time difference is about 10 second.
