Your spoke routers only have static routes to the hub router's outside interface, not the other spoke router. The only default route they have is learnt over the DMVPN tunnel, so that won't work.
Define static routes to the other spoke router's outside interface or better still use VRF on the outside interface. Example here.

here
green orange can summary to 10.0.0./16 "or high superNet"
each spoke tunnel destination must reachable from other spoke, can do that by
ip route 0.0.0.0 0.0.0.0 ISPinterface
that it check this.

dear MHM
Kindly, Iam not tested yet but logically you are right NBMA is the address that must reach from every one
only path for NBMA between spokes is default provided by DMVPN tunnel
you are smart person ..

@saif What was the reason the ip nhrp shortcut was not visible in running config? I am experiencing the same problem, but I am using different routing protocols for underlay and overlay. The NBMA addresses are pingable but I still cannot see ip nhrp shortcut in the running config of spokes.
