If you run Netflix or video streaming it's all too easy to eat gigabytes of data a day. For me TWC has no caps so it's a non-issue. Since your ST phone works at home, I think you are a good candidate for their home wireless system.
I'm considering dumping Comcast for my internet/wifi and going with Straight Talk's home wireless device which would provide home phone service and internet. Has anyone tried this device yet? I have ST for my mobile phone and LOVE IT! No issues, no dropped calls, clear as a bell at home or on the road. If not this *new* device, is there any others that would work in the same capacity for around the same price they are offiering -- $149.99 for the device and then you pick your plan based on usage. Thanks!!
