Please follow below link, if you don’t have login/password assigned, please contact your FAE or sales representative.

To get access to the Sierra Wireless Extranet (https://extranet.sierrawireless.com), you will have to contact your distributor and have them register you with Sierra Wireless. Once registered you will be able to access more detailed mini-card data sheets.
