Hi guys, I have been going around and around with this issue for weeks. Finally, I have decided to throw in the towel and seek assistance. I cannot seem to get tethering AND MMS to work at the same time. Tethering, I finally got to work by changing to (in addition to many other things) ipv6 on the APN on the AP (the tethering phone, my s5). But then I cannot send MMS. I have tried several different APN settings, all to no avail. I was just curious, has anyone been able to get this working?
