hello guys pls i need help

i have samsung C3050, without a sim works just fine, but when sim is inserted the phone turns on for a while ( ~30 sec ) and reads the sim, then turns off automatically.

and i heve another C3053, it seems to have the same problem but slightly different, without sim the phone works just fine, with sim in it, the phone turns on and reads the sim then reboots automatically and it doesn't read sim anymore.

the sim ways are fine as i think and tested.
please guys help me and thanks in advance.

you know it’s a very common problem on this model. 90% of the cases I found liquid damage in the phone damaging the Sim Ic, it’s a little square one near your sim reader, you can also clean around that with a soft tooth brush and mentholated sprits. Don’t fiddle with your sim contact/ reader if no damage visible to the eye.

Kammy6000 thank for your help, but can you specify the location of this sim-ic, cause what i found around the sim reader are battery-ic, bluetooth-ic and diode-tvs ( which i don't know what is it

).
thank you again

another trick cover each pin 1 at a time with small tape you will find problem pin!
or put tape on sim section one each pin test it
