I was having a frustrating time trying to adjust my ANS settings again and again to get my MMS working. I tried the fix that worked for everybody and it wouldn’t work. I used every trick I could find on the internet. Then I gave up and contacted BRAXSim directly. They responded this morning with a new ANS to try. It worked immediately. I’m so relieved. FYI I ported from Verizon. Details below.
