First tests are done the stick is working on the pc. After I connected it to the Lenovo Miix 2 i found out that the indication LED is not giving me a feedback. So far I am sure that the supply voltage is too low. So i opened the the case of the Huawei E3331 to find out if there is a voltage regulator inside to power the device with 3.3V from the source i got in my Miix. I measured the connectors through and there is a 3.3V source so maybe i can connect it directly there to get the modem working…

I choosed the Huawei E3331 even there is at the moment no way for voice calls. The USB stick is really tiny. Huawei promotes it as the tiniest USB 3G stick available at the moment. So we will see… But first i have to make some tests with it on my PC if it works before get rid of the warranty.
