Hi there, I have been told that my recipients get scrambled text messages from me when these are longer than the 160 characters. I also have the same problem if I am sent a message whilst my phone is switched off - I won’t receive the longer text message in one thread, but it will be scrambled as well. Any advice? Thanks!
Maybe this is relevant to you:
If not, I would contact your provider and ask them, if they can provide a solution.
