Can I buy things without texting?

This should be possible to send text messages, because you will know whether you have succeeded in buying things by sending text messages. If you don't want to receive messages, you can cancel the SMS function in the local business hall.

Many mobile apps also provide SMS interception function, which can be set in the app.

1, reply to "0000" directly shielded port. If you receive spam messages from merchants, you can reply "0000" for blocking. After the reply, the operator will send a feedback message, and all notification messages from the merchant will be blocked directly from the operator port.

Call the operator. You can call the customer service hotline of the operator you use and provide the number that has been sending you spam messages. The customer will help you operate in the background and intercept spam messages from now on.

3. Blacklist. For Apple users' iMessage spam messages, such messages are often messy email addresses, which are usually sent directly through the network without going through the operator. To block such messages, you can choose to blacklist this calling number. Another way is to choose Settings-Messages-Send and Receive and turn off your email, so that no one will send you spam messages through your email.
