I'm having no luck accessing the internet on my HTC One with AT&T here in San Jose, CA during phone calls. I have tried many times and it never works. Yesterday I finally tried the speedtest app while on the phone and I got 0.5Mbps down and a solid ZERO upload. Typical in this area is 47Mbps down and 23Mbps upload while not on the phone, i.e. when no voice calls are active . I heard ATT uses 3G for data when on a call but even that doesn't seem to work.
Any ideas?
Thanks!
