SIM card detection issue: Kerlink Wirnet station

We are facing one problem where SIM card is not detected while inserting in Kerlink station.
suspected there is SIM issue but same SIM if we insert in mobile then it is showing working.
but why not only working in kerlink station. please suggest me how to clear this issue.

Please contact your vendor and ask them. They should know if sim cards from telcos in your country could have issues.
