unlock Sierra Wireless 3G data cards when remote unlocking by code is not available for your mobile device. Unlock code is generated by a small client software and entered directly into the modem. No disassembling or techinical knowledge is required.
Sim unlocking allows to remove simlock and use your Sierra Wireless AirCard 875 modem with other SIM cards on other 3G GSM networks such as Tmobile, Three, Virgin, Cable and Wireless, O2, Vodafone, Orange, Movistar, etc
The software has also ability to activate voice feature to perform voice calls. To purchase it select "Activate voice" from the list of options.
