My loyalty has been based on cost, which of late is no longer as much of a difference as it once was. With the added "premium data" charges that many (myself included) don't truly enjoy except via WiFi and the paltry 4G network coverage in my home/business area, the shift in the discount structure and overall family shared plan pricing - the massive delta between my Sprint bill and what a similar plan would be on Verizon is now only a few dollars.
With 2 heavy data users, 1 basically only email and maps, and 1 non-smart phone on my plan, I'm paying $30 extra a month now for ... well for what I'm not sure anymore. Unlimited for me is very limited. I average around 6GB on WIFI and under 1GB on network because of limited coverage at home and at my office (roaming in the break room? Really????)
The coverage maps provided by Sprint are so weak that, even though I'm apparently within 2 miles of a 4G tower (guessing based on the coverage gradations) that I still need an Airave in my home to get any signal at all. I left ATT for exactly this reason and I feel stupid for not listening to my neighbors (all loving their Verizon coverage) because Sprint had the phone I'd been wanting - the amazing Samsung Katana.
I'm off contract now on my on line, and will be next year for 2 others. If LTE isn't here (south Orange County) and insanely good - I'm a goner, and my loyalty will be based on what it should be based on - QUALITY SERVICES.
