Oops, sorry - i should've done a bit more searching
So if I understand correctly the Three "4G Hub" is a ZTE MF286D (Cat12) and the "4G Plus Hub" is a Sercomm something-or-other and is also a Cat12 router?
If they are both Cat12, then chances are they wont be overly different in terms of max download/upload performance given the same Three network masts? So is there any reason to pay Three £17/month for the "4G Plus Hub" rather than £14/month for the lesser "4G Hub" ?
Currently i'm using the Three supplied Huawei B535 which is kinda rubbish, so i'm just looking for something that offers better than that without paying much more than that £15/month I currently pay Three for Unlimited data.
