I am on 3G only, but it still doesn't like it if I don't have at least one GSM band selected ("unable to apply band configuration"). Also does not allow me to deselect UMTS 850, 1900 or 1700, which does not matter because my provider is only on 2100 and 900. Also this modem does not support these bands as per http://en.wikipedia.org/wiki/Huawei_E5#E5756.2C_E5775_and_E5776.
For the 4g settings, when selecting "Automatic", the error message is as per my last post with code 0x10000000000. As per the wikipedia article, E5775 seems to support some bands not listed in mdma.
