I was once a RW "member" as well. I can say that the dial out failures, lag time in voice, failed SMSes, and echoing/static were not great; it didn't happen only on my home WiFi, it was on most WiFi. And then when I would use the Sprint network they would never accurately calculate my CUI... I would never get credit for using the WiFi network, but always get hammered for using the cell network. I really think that this is a very novel concept, one that I thought up (and even have a business plan for) about five years ago... and I do wish them the best of luck. As for me, I am happier paying $3.00 more with T-Mobile and getting the exact same plan, plus great voice quality, good wifi/3G voice handoffs, unlimited wifi/cellular usage, international wifi plan usage, and good customer service!
PS: I finally found a way to use my RW LG Optimus, once it's out of their system, a few days after you request cancellation, then you can use it on WiFi - that's what I've been doing, since they don't sell well on e-bay. If I find a friend in need who has Sprint, I'm willing to give it to them - I did stop by a Sprint store and the gal told me that the phone was able to be used on the Sprint network (contrary to what RW CS had told me upon cancelling).
It was a good experience, I won't be going back... but glad I got to at least try out Android and use the Google Navigation alot while on RW.
T-Mobile. Connecting you when you need it most... disconnecting you when you need to connect with God's beautiful creation! Service is great in cities and highways, but in rural areas they leave you with just your surroundings. I encourage you to get T-Mobile, disconnect for a while!
I am glad that God is not like cell phone coverage. He does not hide behind mountains or loose us down long windy roads. The Lord levels mountains, and He makes our paths straight!
