I've been having a problem occasionally texting one friend and I really want to know what the issue is. Basically, when I send a text, occasionally the words I send will be different from what she receives, and what she receives is usually random words I've said in the past. For example: I send: "the weather is really nice outside. I think its about to reach the 80's next week." She gets: "the weather is really nice outside. I had pizza for dinner." This is assuming that in the past, sometimes almost 5 or 6 months ago, I have texted those exact words "I had pizza for dinner" to her. We both have t-mobile, and I have the galaxy s4 while she has the nexus 4. I use go sms for texting while she uses the default app. She never clears her texting threads so the past words are still in the thread which is likely over 1000 texts long. i'm not sure if the issue is with the carrier as in t-mobile or with the phones or the messaging apps. any ideas?
