haii ..i have bought my samsung galaxy ace one week ago and i started facing problems with it.
i use idea simcard and sometimes it shows emergency calls only though i have a signal . i use only 2g (GSM only).when i find emergency calls only i found that my network changes in status (About phone) to some random network (not idea) and the network type changes to gprs . when the network was idea and network type was edge the mobile works pretty well.
i have inserted my sim in another mobile and checked it works pretty well. and other network sims work very well in samsung galaxy ace . i have tried these.

is the problem with the network signals here ?? why does my mobile randomly take some other network and shows its signal
