Open some mig33 register pages using emulator and fillup the required information.give the same mobile number (unregistered) in all those pages. Before clicking the SUBMIT option pause/hold your GPRS connection. When your connection will be held then click SUBMIT option from those mig33 register pages you opened. Then the registering process will continue at the same time. After that resume your GPRS connection. After a few seconds you will see message showing a confirmation of your successfull registration from multiple IDs you just registered and you will get different authentication codes via sms. Thus you will be able to register multiple IDs with a single number (2 try it out u can open 15-40 mig33 files or how many you want at the same time. Its doesn't mean that all these IDs will b registered but u would be able to register some of these IDs).
