Just wanted to add that I too am in the San Antonio area, and somewhere around the second weekend of September 2011, both my Hero and my wife's EVO 4G lost the ability to make calls. We could still receive them and still had texting, MMS and full web access though. I spent some time trying to work with Cricket on a resolution, but they failed for three weeks straight. I posted a help request on howardforums and whitey10tc summarized and directed me to this post. I just wanted to reaffirm that enabling EVRC and setting home page, home orig and roam orig all to EVRC returned our ability to make outgoing phone calls. So a big, BIG thank you to everyone involved in providing this solution!!!

Awesome! Glad you got it going! Thanks also to whitey10tc who helped to guide me to where he/she thought the problem was (in the evrc, or 13k) option.
I'm glad I took a chance on trying what turned out to work because it did work and that's all that matters. I've had no problems since then.
