This thread may already exist if so,sorry. I have a dell streak 7, I want to download android app "Ooma mobile", they tell me that my device is not compatabile. I have android version 3.2 in the dell. I have downloaded other android apps with no problem. Could it be that The sim card I used did not have 3G service? I don't want to get 3G service unless I can get this app to work. Is there anything I can do to make the dell compatabile?
