A little bit similar problem is with Reliance GSM. there are some 6-8 fixed time slots in a day when u can't connect to GPRS whatever u may try for nearly 20-30 mins. & it is the same time when there CC says their system is in process of update (i.e. updation of User a/c like addition/substraction of amount details become accessible to the CC). Some times its just annoying. :impissed:
