My small development firm just switched over AT&T to Consumer Cellular. Everyone in the firm is a low-bandwidth data user, we were able to switch over with caps of 200MB to 1GB for individual users. Additionally, we were using AT&T and Consumer Cellular rides on top of AT&T. All our existing GSM phones simply worked. The changeover to Consumer Cellular was pretty cheap, and we're saving a chunk of change on our monthly bill. (I am in no way shape or form affiliated with Consumer Cellular, scouts honor).
Here's the question: I have two big clients in the Denver Metro Area who spend a lot on Verizon. Consumer Cellular would not an option for either client because AT&T coverage in the Denver area can be pretty spotty. Is there a "Consumer Cellular equivalent," that piggybacks on the Verizon cellular network and could save them some money? Like my firm, all users require data, but many use nominal bandwidth.
It's worth noting that I'm assuming that their Verizon-compatible CDMA phones would work with a carrier that piggybacks on Verizon. That assumption may be wrong.
