I have problems receiving text messages when I am one of multiple recipients, it tells me the message failed and then I have to download it. It does this also with receiving pictures in the texts when I am the only recipient. And usually, fails when I try to send texts/pics to multiple recipients. Any fixes?
I have a check setting on my Samsung if I want to be notified when an sms is being converted to mms.
You can send text to multiples but I am not sure at what amount regular texts are converted to mms.
I agree in your instances they are coming in and going out as MMS messages, and you need to be set up for that, as it is data. SMS texts use gaps in voice signals.
