I'm having trouble receiving text messages from my sister. She receives all of my texts. When she replies, her phone shows her messages have gone through but I never receive them. This isn't related to just one phone. I've had 3 different phones since this started. I'm thinking maybe somewhere in the past I may have mistakenly blocked my sister's number from receiving incoming messages. Its the only thing that makes sense to me but I can't find anything anywhere here on the website to tell me if that's what happened. Its really a pain in the butt to get any info from her. She is able to text our other family members but either has to have someone relay info to me, email me, or IM me through social media.
Anyone have any ideas?
