A few weeks ago I purchased a nexus 4, my service provider is t-mobile and all of a sudden i'm having a problem sending picture messages
.. When I first started using the phone it worked perfectly! But now for the past week it's not been working. I contacted customer support on the issue and they told me to call technical support. I have not called them yet because i'm hoping to get the answer I need on here.
What I have done so far is change the APN settings, even created a new one with the help from the tmobile customer service and there was no luck. Any ideas on what I can do to fix this problem? Any other information needed please let me know. Thanks.
