Xperia Z1 MMS issues

[Esque]

Having some frustration with MMS. I understand that MMS go through the mobile network, and when your on WiFi, mobile data doesn't get used.

When I have them both on, MMS will not send nor receive. Turn off WiFi and and it works. Is there a way around this incovinience?

MMS goes over mobile data connection, not wifi.

MMS should also work when WiFi is on (but it uses the mobile network). I would recommend that you first check the APN-type of your MMS settings. Go to Settings -> More -> Mobile networks -> Access Point Names -> [your MMS settings]. Check that the APN-type is set to "mms".

Have checked my APN settings, the MMS APN is configured to mms under APN type and all others looks normal according to my carriers APN settings. Still getting the message 'Unfortunately, Messaging has stopped' when sending an MMS with BOTH Wi-Fi and mobile data turned on.

Which software version do you have in the phone? You can see this under Settings -> About phone.

Does it also happen if you start the phone in safe mode (http://talk.sonymobile.com/t5/FAQ/How-to-boot-your-phone-into-safe-mode/m-p/348008)?

I have the same problem. Thou MMS works when turning off Wifi. If I Try to send a mms with wifi on, the whole messenger app crashes and no mms can be sent . Why does this happen?

i too have that problem and when u want to manually change mms portal settings the apn vanishes.... the mms does not go what so ever...

If MMS works fine when WiFi is turned off but not when you turn it on, please send me a PM with relevant topic and the following information and i'll forward this for further investigation:

Name:
Phone nr:
E-mail:
Country:
Operator:
IMEI nr:
Build number:

If the APN vanishes when you create/edit it you have probably entered wrong MNC/MCC. The APN is saved but not displayed if the MNC/MCC doesn't match the network and SIM.
