When sending a voice message, what numbers should be added before the other party's mobile phone number?

Fee structure: phone bill+voice short message fee

Call charges generated by dialing 1 and 12536: Local call charges are charged according to the local call charges of your brand, and will be charged according to the specified roaming call charges when roaming.

2. Telephone charges generated by receiving voice messages from 12536 when called: Local telephone charges are charged according to the local telephone charges of your brand. When called, roaming charges plus long-distance charges are charged regardless of whether you roam in the province or across provinces.

3. Receiving the SMS of 12536 is free.

4. Sending voice short messages: charge by article, 0. 1 yuan/article, which is included in the short message fee.

You can call 12536 directly to use the voice short message service without applying for or canceling the service.

Unicom's new power users:

There is no charge for calling 10 158. You can also dial 10 158 to send voice messages, and then send them after recording. The fee is 20 cents, or you can add 5858 before the other party's number after editing the message, and the other party will receive it from a super funny computer. Add 10665599 before answering the supplementary number to send the voice message.

I suggest you don't add it casually. This SP service belongs to the whole country, and it is generally 2 yuan/article or monthly.
