I reviewed my wife's N900A with T mobile sim card in it, the APN was actually set to T Mobile but some fields were different to my N900T on T Mobile. I do not remember which lines to be honest, I just copied mine on to hers. I think the field APN type on hers was just set to "default" where as mine is set to "default,mms,supl" .
I also believe her APN was not "fast.t-mobile.com" .
Her N900A seems to be picking up good LTE now, just originally when I first powered it up after unlocking the LTE icon would come and go in the home. I was thinking perhaps the N900A stock does not have all the radios available?
