Text messaging on cell phones is expensive if you do not have a text-messaging plan in place. Activating a text-messaging plan allows you to receive unlimited text messages on your phone. Blocking numbers from sending you text messages in the past means you need to unblock the cell phone numbers to receive their text messages in the future. Unblocking cell phone numbers from sending a text message to your phone is a task any individual can accomplish with her own cell phone.
Step 1
Write down the number of the individual you want to unblock from sending you text messaging. Obtain this number from the person directly, or from past phone records.

Open up the text-messaging option on your cell phone. This is done by clicking the "Menu" and "Messaging" option on your cell phone, followed by selecting "New Message."
