My mobile phone is Nokia C5-03. I don't know how to block service messages. How can I call it back?

Hello, check the phone settings ~ or consult the operator to see if you have turned off the SMS function! If you are often troubled by harassing calls, you can try to install Tencent mobile phone housekeeper to intercept defensive harassing calls. In addition to intercepting and marking harassing calls, housekeepers can also intercept spam messages and blacklist annoying numbers. The operation method is as follows.

1. Install Tencent mobile phone manager and turn it on. The manager will automatically intercept "ringing phone" and "common scam messages" and prompt you to mark them.

2. After interception, you can only view the intercepted phone records through the "Harassment Interception" function in "Security Protection".

3. The housekeeper also provides the function of modifying the "mislabeled" phone. At the "Digital Mark", click "I want to correct my mistakes" to make changes. At the same time, you can see the latest marked numbers here, as shown in the following figure:
