How do I install and configure my Huawei E3372s
The Huawei E3372s can be used as internet failover in combination with a FRITZ!Box, meaning that the FRITZ!Box will automatically route your data traffic via the Huawei E3372s if your edpnet internet connection fails, and vice versa when it’s restored. The Huawei E3372s is not eligible for use with your laptop or tablet.
Note: The Huawei E3372s supports 4G LTE, 3G UMTS, 2G GSM. Neither a SIM card nor a mobile internet subscription is included. The stick is unlocked: you can use a data SIM card from the mobile operator of your choice!
Prepare the Huawei E3372s for use
Once you have received your Huawei E3372s, you will need to insert a SIM card into it. As mentioned before, you can use a SIM card from a mobile operator of your choice.
Insert the Huawei E3372s in the FRITZ!Box
With a FRITZ!Box 7430 you should plug the Huawei E3372s into the appropriate USB slot on the side of the modem.

With a FRITZ!Box 7530 you should plug the Huawei E3372s into the appropriate USB slot on the side of the modem.

Under Internet Connection, choose the Other operator as Mobile communications network provider and fill in Access Point, Access Number, User name and Password fields. This information depends on the mobile operator you use. Although you may find these details on the website of your mobile operator, the fastest way is to contact their customer service.
After you have received the necessary data from your mobile operator and have entered it in the FRITZ!Box, press Apply to continue. If you have entered all the required data correctly, the Huawei E3372s will be ready to provide failover in case the fixed edpnet internet connection would fail.
