For anyone who needs voice, message, and internet packages for their phone, Verizon is the best option. I think it’s pretty obvious that messages are now the most common way to communicate with everyone. However, a few Verizon users are experiencing the Error 4: Invalid Teleservice ID error on their messages. In light of this, we have added the troubleshooting methods in the article below to help you out!

Troubleshoot Error 4: Invalid Teleservice ID

1. Contact Issues

Firstly, you need to check if the error and message issue occurs with one contact or all contacts. If the error only occurs with one contact, it’s pretty clear that there is a problem with the connection to that specific contact number. If the error occurs with every contact number, you can move on to the next step.

2. Messages+

If you cannot send messages using the default messaging app, we recommend using Messages+. The connections are streamlined as the app is controlled and managed by Verizon. Ultimately, try different messaging apps before dialing Verizon.

3. Device Updates

The issue occurs most of the time, even if your phone is experiencing security or software issues. The error might occur even if you have recently updated the operating system or software. To fix the error, it is suggested to take a step back with software and operating systems.

4. Wi-Fi Calling

There is a chance that you have switched on Wi-Fi calling on your mobile phone if you are a Verizon user and experiencing the Error 4: Invalid Teleservice ID error. You can disable the Wi-Fi calling feature through the advanced calling settings with an Android smartphone. If you are using an iPhone, just ask Siri to do the magic.

5. Toggling

Error 4: Invalid Teleservice ID can occur with network issues or weak signals. You need to give the signals a fresh start in this case. The network infrastructure may also perform inefficiently. You need to toggle the airplane mode off and on a few times. When you toggle on the airplane mode the last time, wait at least thirty seconds before you toggle it off.

6. Reboot

Error 4: Invalid Teleservice ID error may be caused by minor software glitches in the phone. These glitches could impact performance and service quality. In this case, you should restart your phone. You can reboot the phone by pressing and holding the power and volume down buttons. After this reboot fixes the probable network and signal problems, you can send and receive messages again.

7. Factory Reset

Sometimes issues are too significant to be resolved by a simple reboot. We know you don’t like factory resets, but this is one of the best ways to fix Error 4: Invalid Teleservice ID. Simply factory reset your phone and insert the stings again, and you should have a streamlined connection.

8. SIM Card Tray

When Error 4: Invalid Teleservice ID prevents you from sending or receiving messages, you need to check the SIM card tray. It is suggested to replace the SIM card tray because an ineffective tray may result in signal issues.

9. Bluetooth & Network Issues

Bluetooth is one of the easiest ways to share media. As a result, the signal quality can be affected, leading to Error 4: Invalid Teleservice ID. Therefore, we suggest switching off the Bluetooth and sending the message again. We believe that you will be able to receive/send it this time. Besides Bluetooth, there is a possibility that the network settings were incorrect. Reset the network settings if necessary.

10. Location Settings

If your location settings are incorrect, there is a high probability that you will encounter Error 4: Invalid Teleservice ID. Therefore, make sure your location settings are correct. You should also set a valid date and time.
