Yesterday I switched my wireless carrier from At&t to Verizon. After turning on my new Verizon phone (which had been properly activated and was making calls), I saw that not all of my contacts had transferred so I turned on my At&t phone to manually enter the missing contacts. My At&t phone then began receiving all of the text message responses from friends that I had not been receiving on my Verizon phone (I at first figured they chose not to respond). Will this problem correct itself over time or do I need to contact Verizon?
