In this article, i will use MPT sim card to access 4G internet for my LAN Users.
(1) Insert MPT sim card in slot 0 at the back of the router.
login into the router and set hostname
Username: cisco
Password:
% Password expiration warning.
-----------------------------------------------------------------------
Cisco Configuration Professional (Cisco CP) is installed on this device
and it provides the default username "cisco" for one-time use. If you have
already used the username "cisco" to login to the router and your IOS image
supports the "one-time" user option, then this username has already expired.
You will not be able to login to the router with this username after you exit
this session.
It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.
username <myuser> privilege 15 secret 0 <mypassword>
Replace <myuser> and <mypassword> with the username and password you
want to use.

Enter configuration commands, one per line. End with CNTL/Z.

Configure Cellular Profile
Cisco819#cell 0 lte profile create 1 MPT
Warning: You are attempting to modify the attach profile.
Please consult the service provider before doing so.

Profile 1 already exists with above parameters. Do you want to overwrite? [confirm]
Profile 1 will be overwritten with the following values:

Authentication = NONE
Are you sure? [confirm]

As my router can route to internet, so my LAN Users also want to route to internet. So, we need to setup up NAT on the router.
I also create DHCP Pool for LAN Users and set NAT for that.
Cisco819(config)#ip dhcp pool LAN-User
Cisco819(dhcp-config)#network 172.16.1.0 255.255.255.0
Cisco819(dhcp-config)#default-router 172.16.1.1
Cisco819(dhcp-config)#dns-server 8.8.8.8
Cisco819(dhcp-config)#exit

Cisco819(config)#interface vlan 10

Assign access port to fast Ethernet ports f0 to f3
Cisco819(config)#interface range fastEthernet 0-3
Cisco819(config-if-range)#switchport mode access
Cisco819(config-if-range)#switchport access vlan 10
Connect your Laptop to router's fastEthernet Port and route to internet.
Hope you enjoy learning
