I have a Samsung i7500 galaxy and the firmware version is JB2.I am in India and i am using a Vodafone prepaid sim.When i switch on the phone everything is normal but after about 10 mins the network bars shows 0 with a cross and says "No Service".If i reboot the phone or switch between normal and airplane mode it becomes proper again but for 10 mins only.
Is there any permanent fix for this problem??
