My plan with the device is to take it abroad to Austria, Germany, Italy, etc. and buy a domestic prepaid sim card with xGb charge and then plug it into the Huawei and use the internet. Is that possible?
Yes, that works. However, life is made easier if you look for a provider where you can top up and check the credit by SMS. You can send and receive an SMS via the web interface of the E5573.
