Hello.
For 3G you need "ppp" encapsulation; "slip" is for GSM and 4G.
You would better make your connection persistent, so won't have to wait for interesting traffic (and face an issue with SLA).
Also I think it's better to configure Dialer interface instead of physical one.
PS: take a look at VPN Remote Site over 3G/4G guide.

Hi ,
I understand , but when i issue command i get
ustanicka(config)#int cellular 0
ustanicka(config-if)#encapsulation ?
ppp Point-to-Point protocol
slip Serial Line IP
ustanicka(config-if)#encapsulation ppp
Cellular0: Only SLIP encapsulation supported
Any idea?

As you can see few sites use same (nated ) public ip , so some dmvpn tunnels dont works.
Any solution for this ?

Hello.
Yes, buy public IP from your 3G provider.
