I have a Samsung Focus 2. H2O Wireless is the carrier. Cannot send or receive MMS. I downloaded Wireless Manager from the Samsung Marketplace. Spent all day inputting different data found from online searches into the various APN fields. No luck. Recently, I updated to the 7.8 os. Still no luck. I contacted Samsung support and they said that only the carrier could solve the mystery. I contacted H2O wireless support and they said only Samsung could solve it. LOL. Any suggestions from WP/Samsung owners?
