Why can’t my vivo phone send text messages?

If you are using a vivo phone, you can refer to the following troubleshooting methods:

1. Some text messages cannot be sent

1. Confirm whether the phone bill balance is sufficient

Please confirm whether the credit on your mobile phone card is sufficient. If the credit is insufficient, sending text messages will fail.

2. If the text message contains sensitive words, the other party cannot receive it after sending it.

Please use test statements to send text messages to confirm whether the other party can receive them normally, such as: Hello, thank you, etc. If the other party can receive it normally, it means that the text message sent before may contain sensitive words.

3. Confirm whether the "fixed dialing" service has been turned on

After turning on fixed dialing, messages can only be sent to contacts in the fixed dialing list and cannot be sent to other numbers. If you want to continue sending text messages, please cancel the fixed dialing service. Enter Settings--(Applications and Permissions)--System Application Settings--Phone--Corresponding SIM Card--Fixed Dial, turn off fixed dial (the PIN2 code that needs to be entered when turning off needs to be consulted with the operator)

The contact numbers of China's four major operators are: 10099 (China Radio and Television), 10086 (China Mobile), 10010 (China Unicom), and 10000 (China Telecom). You can call them when you have time.

4. Unable to send text messages to some short numbers

Please enter the message APP--three dots in the upper right corner--Settings--More settings--Send paid messages, recommended settings for every inquiry.

2. All text messages cannot be sent

1. Confirm whether the credit balance of the mobile phone card is sufficient

Confirm whether the credit balance of the mobile phone card is sufficient. If the credit balance is insufficient, sending text messages will fail.

2. Turn flight mode on and off

You can try turning flight mode on and off and re-triggering the network before trying.

3. Check whether to use a third-party SMS APP

4. Check whether the SMS center number setting is correct

*Note: You can also check the local SMS center number by checking other mobile phones around you that use the same operator's SIM card.

5. Comparative test of SIM cards

It is recommended to put the SIM card on other mobile phones to send text messages for testing. If the sending still fails, it is recommended to consult the operator's customer service.
