I don't know if the subject is already actual... but, as nobody (more competent than me - means most people on this forum) answer, i try to : Personnly, i meet not this on my device. do you try to activate (& change) the PIN on the android device and go back to the ut one ? if don't works, do you try to re-install UT on your device ? does it can come from your opeator : pearaps some of them considere UT device not as phone ? (but as objects or 4G box). So they could treats it differently.
