That means it is the network at fault.. I thought its my phone coz no one raise this issue here.. I reformatted my phone and still the same.. what do u do if it failed to connect? In many occasions, I restarted my phone, go offline and online again, but still cant connect.. The only solution is to wait 

is been quite a while happening in penang, they actually put coverages in U mobile websites then they remove it, and the U mobile service centre in penanag @ queensbay mall even say they dont dare to encourages people suscribe to u broadband and they say is better to suscribe to u mobile internet plan,.. and i did try out but U mobile network in penang is not really stable even in 42MBps area,... same thing happen like you guys,.
