I have an HTC One through ATT and my wife has a Samsung Galaxy. We love our phones but are conflicted about the monthly bill we get. Usually, it is just under $160 for the two of us. We don't like to worry about usage and so this is OK but seems steep to us today.
The screen on my HTC One just cracked again for the third time and so rather than going to a local shop and having them fix it for $100, I am considering this option on eBay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=191196586810
Before we go that route, we want to at least check and see what the best prices are on SIM cards, irrespective of whatever phone we get. I would want a SIM that would at least allow some tethering because it is a need periodically. We use some data and text, but not a lot.
What Smart Phone capable SIM choices are out there if we wanted to go totally pre-paid with no monthly commitment whatsoever?
