Hello,
Please do the following:
- Power on the router with SIM card inserted into it
- Make sure that correct mobile settings are being used in "Network -> Mobile" menu (APN, authentication, etc)
- Wait few minutes
- If router would not have internet connection, download troubleshoot package form the router and send it to me via private message. Troubleshoot package can be downloaded from "System -> Administration -> Troubleshoot" menu.
