I recently moved to Zurich, Switzerland for a couple of months from India
I took a Sunrise SIM prepaid card as soon as I reached here, but I am unable to receive the phone signal at all. Some times I am without a signal for hours together.
I am running GAOSP Public Beta 3 with JC6 Baseband (I7500XEJC6)
Is it a problem with the baseband because the same SIM card works fine in another mobile phone? Or have Sunrise blocked my phone because I am using different ROM like GAOSP?
