Hi

I have a RGKNSE R-sim and I did manage to unlock it successfully once and used my iPhone 4S 5.0.1 however soon it lost signal. Now I'm trying to using another micro-sim with the R-sim and it completes all the steps and even shows my operator's name but there is no signal. The instructions don't make sense to me about what I must do in this case. Can any one help?

Thanks
