    Dear OnePlus Community,

    need a solution for following issue:

    everytime I receive a MMS for example a picture my mobile internet connection is disconnected for a while additionally a "!" appears next to the mobile connection sign. If I do nothing it gets back after a while and my only work-around is to disconnect mobile transfere manually and re-connect it.

    First I suspected a failure with my sim card A1 Austria, but since I used the phone in Thailand with AIS and a different sim same failure appeared.

    So I think it is a certain setting that disconnects my mobile internet upon receiving a MMS.

    Does anyone have the same issue? All setting by my provider a acurate and checked.

    @OnePlus: Need support!

    Thank You,
