Just picked up my v3 micro sim from koodo for my new Nexus 4. Data is working fine on both HSPA and LTE however I cannot send mms Even when at home on wifi it wont turn on data to send it. This happened before on my Nexus S a year back but it fixed it self. I tripped checked the APN settings and all is good so not sure why it wont send. I am using SMS Go but I have also tried it on the stock msg app. Just a note Speedtest.net always has a connection error on data but wifi is fine. Not sure if this is linked in anyway.
