So I have an LG Optimus Slider with Virgin Mobile. I have had this phone for months without this problem. I changed my phone number today, and now I cant recieve or send texts from certain contacts and I dont know why. Ive tried deleting all my contacts and re adding them and even did a factory data reset. I also activated my new number after getting it. Any advanced ideas on how to fix it? My phone is rooted with superuser permissions, if that helps at all. thanks
