For now the only plan you can get unlimited is from sprint... until they stop offering it. All the other unlimited plans are ONLY for use on the phones themselves. If you tether them they have caps and extra charges.
Don't think you can sneak a tether past them. They can easily tell from the type of traffic if it is a PC or a phone. Your web browser will tell on you with every request since it include the OS and other info.
carriers right now? I've been doing this on TMO for about the last 30 days, and finally hit their ceiling and received several text warnings about being shut off/throttled.
I'd rather not sign up for a local ISP since I'm already paying for unlimited data, and my speeds have been very good (5-10 down) with my 4G access through TMO on my HTC G2. That's been my thinking...until these warnings.
I've already talked with TMO customer service and confirmed...unfortunately, I've hit the wall there and it's got me looking at the competition. It looks like Verizon also promises "unlimited" data, but there's fine print. Anyone have experience pushing more than 10 gigs per month off tethering from their unlimited Sprint or Verizon plan?
I HATE AT&T and will never go back, so they're not an option.
