I got looking closer at the plans for California and Nevada, and they aren't so hot once you notice this: henever, Wherever in the US The National Plan gives you: One flat rate per month Calls to anywhere in the country with GSM coverage Calls from anywhere in the country with GSM coverage No long distance or digital roaming charges So, what happens if you call an area without GSM coverage? There are an awful lot of areas in the US without GSM coverage. California & Nevada Neighborhood which includes California and Nevada. Regional Rate Plans offer: Calls to and from anywhere within this region--you pay no long distance or roaming charges Calls made from within the region to outside the region incur long distance charges Calls made from outside the region incur long distance and roaming charges So, you get charged LD to calls outside this area, and on top of that, if you go outside this area, you pay roaming plus LD. Not too hot in my view.
