How often have you tried to quickly look for something on your phone, and can't pull it up? Your signal is weak, or maybe you hit a dead zone.
It's something you want to know *before* buying an expensive plan.
Recently, we were with Tony Hoffman and Angela Moscaritolo of pcmag.com.
They were in the Valley testing ATT, Verizon, T-Mobile and Sprint for speed and reliability. It's part of a yearly nationwide test.
The testers pick more than a dozen locations throughout the Valley. They then test upload, download and ping speeds for at least 15 minutes at each site.
Already, the testers say they found one carrier with a dead zone.
Last year, Verizon came in first in the Valley and Sprint finished last. This year's results will be released in June at pcmag.com .
Do you have any problems with your phones reliability?
Hit any dead zones? Where are they?
Let me know.
