Question about Samsung BlackJack II Smartphone
This is a simple issue don't worry.First please remove the battery and remove the SIM card and see weather it is being damaged or you can see scratches on the gold plating.Take some cotton and dip it on kerosene and clean it nicely on the edges of the gold plating of the SIM card..Now place it correctly and switch on the phone.Some time loose contact may cause this problem and scratches too....If
still the problem persist check with other Sim card of your friends or family members..
If other SIM card is work's fine then it your SIM card must be replaced by your service provider.Ask him for a free replace..else the Sim card
connector is damaged you have to solder or replace it.If you don't have any hands on,take it to nearest service center.
Note:some time signal strength of the network provider might be weak so it will say have emergency mode.Go to any outdoor area and check for good signal reception.
Please do rate the solution if the issue is resolved or post a comment for further assistance.
