Yes I have bought an unlocked IPhone 6s Plus set from LA, USA from apple store last Dec. APN setting is proper and have cross verified from carrier as well. Right now I am located in Karachi, Pakistan......Here my MMS issue is resolved after setting correct APN setting and now able to do group MMS as well but unable to do group sms text yet. When ever I do group sms text it convert it to group MMS , I unable to trace out yet the reason of it why it happened.
Well, as you know, you have numerous issues going on here. Since this is a US phone, it is likely not supporting all bands in your local area, they are not designed for that. To my knowledge, I believed that all group text goes as a MMS, but I could be wrong. I know that if you have a mix of iPhone and non-iPhone users in a group message, it is sent as an MMS. Either way, as the other poster has indicated, your issues are with your carrier, and not the iPhone.
