Hello Mufeed,

either you change the router with one supporting LTE  or you change the SIM with one supporting GSM services

 

Hope to help

Re: Cellular LTE profile

Hi Giuseppe

Thank you for your reply
I purchased a LTE supporting modem and configure the sim on the same and
connected the modem to Wan port of Cisco router, now it's working fine

For my knowledge can I ask, is Cisco 881g router will support LTE if I
update the IOS

Re: Cellular LTE profile

Hello Mufeed,

I am happy you have found a solution to your issue.

 

Upgrading the IOS can also upgrade the firmware of the modem inside the router.

However, if the embedded modem is not able to support LTE for hardware limits.

 

we should look at C881G datasheet to see what is declared to support.

 

>> Multiple WAN links include Fast Ethernet, multimode VDSL2/ADSL2/2+, multimode G.SHDSL, 3G, and ISDN

 

see

https://www.cisco.com/c/en/us/products/collateral/routers/887-integrated-services-router-isr/data_sheet_c78_459542.html?dtid=osscdc000283

 

So I would say this router 881G can support only 3G not LTE.

 

Hope to help

Giuseppe
