are you on 8.1 or the W10 preview? this is what I have used for years. currently using on a 930 running build 10166 of W10P. Also, did you restart your phone after adding the data and mms apns?I have tried all the settings on this blog and they are no longer working. I am pretty sure they worked before. Does anyone have an update for the codes for the Lumia 1020 ATT phone on Straight Talk? After Windows updates, my phone will no longer send and receive photos on Straight Talk.
Oops. Just saw that it may take a day. Will update.
