I have an alcatel OT800 and been receiving unwanted texts from someone, how do i block their number so they do not have access to text or phone me.

1 Call you cell phone service provider and tell them that you want to block text messages from a certain number. Your provider will stop all texts coming from that number

Reply to an unwanted text from a company or organization with "unsubscribe." If you're getting SPAM texts, this should make it stop.

Check out the website of your cell phone provider and look for the option of logging into your account. Most companies allow users to set up preferences in regards to their text messaging, including blocking certain numbers.

Change the text message settings on your cell phone. Depending on the model you have, you may be able to block certain numbers just by changing your settings
