Re: Roaming Agreements?

Verizon and Sprint both use CDMA however all Sprint roaming has been removed from the PRL in the NY area for about 3 years. This means that a Verizon customer can not make a call on the Sprint PCS network even if the phone is showing No Service and he is standing next to a Sprint tower.

The E911 rules however require any compatable carrier to accept a 911 call from any compatable phone, even it it is not activated.

If Sprint isn't in VZ's PRL, then will 911 still go thru Sprint's towers in the example you used (no VZ reachable) on a typical CDMA phone that was most recently on VZ's network that has VZ's PRL loaded?

Yes 911 overrides the PRL table. 911 looks for any signal using a compatible technology and frequency to connect.

As I said, you can make a 911 call with a phone that is not even activated so the assumption there is that there may not even be a valid PRL in the phone.
