I am having problems with my sms texting. I am able to text anyone I want except for this one person. I text this person the most so I do not know what the problem is. I was able to text this person back up until last night and thats when it started not letting me text that person. I can receive text messages from that person but I can not open our text conversation. When I click on that persons name it does not open. I can open all my other messages and reply to them. Please help!
I would try deleting the contact info for that person (after writing down the info to manually add later). Then do a battery pull by removing the battery while the phone is on, leave it out for a few seconds, put it back in and wait. Once your phone resets, add your contact's info and try texting him/her.
