Otto, That would be great if a moderator from this site was able to accomplish what countless number of AT&T Tech Support Reps are unable to do! 

I plan on calling AT&T Tech Support tomorrow to let them know that replacing the microcell with a new microcell didn't work.  At least I was able to get a full refund for the first microcell and got the second new microcell at no cost. 

I've put in lots of time and effort with my multitude of telephone calls to AT&T Tech Support and at this point I feel that all my time and effort was a waste. 

I sure wish I could use my AT&T cell phone at my home though.
