Hello and Welcome to FixYa!
Inactive SIM message may arise due to more than one issues. First things first check the hardware of your phone, to do this Put out the SIM card and check what happens. If it shows insert SIM card, its normal. If it shows the same inactive message then hardware malfunctioning.
Ok if the hardware is ok, then its simple. Inactive SIM means that your SIM card is not being able to register your Network carrier. The Phone with a red-line means SIM card registration failed. Although the signal radar works. This may be due to 2 issue; either there is a issue at the Service provider End, to check this call the service providers from other cell or land-line and check the status of your connection against this SIM Card No. If they say everything is ok. Then Its confirmed that your Phone is Network locked (Can only be used for one specific network) In this case coordinate with the seller.
I hope you will have a clearer picture now.

If you have any Confusion, questions or issues regarding your problem do tell me.

No, its not the signal problem. It is infact ur SIM problem. U will have to call back ur network provider to resolve this. an inactive sim is always as good as dead sim. Ur SIM automatically gets inactive by ur network provider if not used (switched off mode) more then six months.

Hope this helps.
thanks

You SIM card is inactive. You have to make at least 1 paid call every 6 months otherwise your sim is deactivated. If it's new sim has to be activated.

That's it. Your phone is ready to accept SIM cards from just about any GSM mobile telephone service provider in the world. If you received a "wrong password" message you will need to insert a working SIM and reset the password to the default 8 zeroes "00000000". After that you may try this process again and it should work.

you could try this

By doing the reset (1st temp) you will lose all your
data ie contacts, messages, photos, videos etc etc so
back them up on your pc first.
Take out your sim card and follow the instructions below :
1st temp. put this number in the keypad
*2767*3855# let it reboot(restart)
now its ready for permanent.
Put in a sim card of a network that the phone won't
except and follow the instructions below.
( If you can't type anything with a locked sim
card inserted just take it out and do the next
step without a sim card in the phone)
Don't worry if your screen shows - - - - - - - when typing
it is supposed to do this.
Permanent.
ENTER :
*7465625*638*00000000*0000000
0#
NEXT ENTER
#7465625*638*00000000#
AND THEN *#7465625# to check the locks....all locks are
inactive...these are all the locks...
network lock - inactive
subset lock - inactive
sp lock - inactive
cp lock - inactive
sim lock - inactive
activa lock - inactive
phone lock - inactive
auto network - inactive
auto subset lock - inactive
auto sp lock - inactive
auto cp lock - inactive
auto sim lock - inactive
Enjoy !
This procedure does not change your imei number at all

hi
Try with all the code to see whether you can get one to unlock your phone. If all still cannot help then you can only contact Samsung Support for help. I hope these information below at least can give you some hints:

Note try codes which help direct unlock for either SIM Lock or Security Lock first before try other codes

*7465625*746*Code# = Enables SIM lock
#7465625*746*Code# = Disables SIM lock
*2767*2878# (Temporary Unlock)

#7465625*638*00000000# (Clear Network Lock)
*#7465625# (Verify the network lock is “inactive”)

*2767*3855#
*2767*3855# - FULL E2P RESET
*2767*2878# - CUSTOM E2P RESET
#*7337# - UNLOCK

*#0523# - CONTRAST

*2767*3855# (wait 10-15 seconds) phone will reboot(restart)
When phone completes reboot ENTER
*7465625*638*00000000*00000000#
