I agree do not commit without POC or trial bases.

I've seen it with "static" public IP pppoe assignment.

No NAT.

Reliability?  Best effort at best.

Coverage area is ok.

Speed and reliability is completely dependant on your location.  Test first.

Always.  And then do not set a decent expectation.

IPSec tunnels dropping?  Could be.  Again, depends on your locations.

My overall impression?  Get a T1.

My overall recommendation?  Complete site surveys and then have a back out 
plan.

I'm considering use of AT&T / Verizon / Sprint WWAN services and the
Cisco 3G router interface cards/integrated module in C880 routers for
primary or backup WAN network connectivity for routers.

I'm looking for information from users of these services on the
following:

- addressing - Do these WWAN services use dynamic, PPPoE or static IP
assignment typically? Any of the 3? All?
   - is static IP assignment available?

- do these service providers use NAT within their network?

- How is the service reliability?  In most cases, is the service
available for use when you need to use it?
- How is the service coverage area?  Do you have problems getting
sufficient coverage in the deplouyment location to support desired
speeds (say 512kbps up/down as a minimum)?
- is ESP / IKE / IPsec permitted through un-rate-limited and un-molested
by the providers?
- If you build a IPsec/GRE tunnel over these services, do you have
frequent issues with the tunnel dropping, or a dynamic routing protocol
running through the tunnel going down frequently?

Also interested in similar information on impressions of similar EMEA
WWAN service providers, particularly Vodaphone and T-Mobile, if anyone
has experiences with these.
