[Q] unlocked att htc m8 cannot send/receive mms
I sim unlocked my htc m8 and am now using a tmobile sim card. 4G network, calls, sms everything works just fine. However, i am not able to send/receive mms. I called t-mobile for help, and they told me to change my apn setting, which i did. And that only fixed my problem with 4g data(i initially had problem with both 4g data and mms) No matter what i try for apn setting, MMS won't send.
My current apn setting is: apn:fast.t-mobile.com
mms protocal: wap2.0
apn type: default,supl,admin,dun,mms
everything else is not set. I really don't understand why would mms not work if both 4g data and individual sms works.
Anyone have an idea?
