There is a very large branch of a multinational defense/engineering/aerospace company at the intersection of Bolsa Chica and Bolsa in Huntington Beach, CA.
It is full of thousands of people who have:
1: money
2: a love of technology
3: high standards
Every day, those of us on Tmobile plans deal with the fact that we have practically no signal (in some cases: no signal at all) inside the buildings onsite while our AT&T co-workers have no issues and get full coverage everywhere.
They laugh, they point, and you are losing customers.
Help us.
