Whenever I Turn On My Phone It Says That The SIM Card Must Be Inserted, Even Though It's Already In.


The SIM card may not be making proper electrical contact in the cell phone.
Try removing the SIM card and cleaning the SIM card contacts and the SIM card contacts in the cell phone with methylated spirits. Then replace the SIM card in the cell phone.

I put the sim card in and it says insert sim card


Hi, when a phone says insert Sim,is either the Sim card or the Sim seater that allows the Sim to work is bad.

First try the Sim card on another phone and see if it will display insert Sim again.If it display that means the Sim card is damaged. But if no display,that means the Sim tray of your phone is damaged and will need to be replaced.

Contact a skill prsonnel.
Take care.

My pantech matrix cell phone says insert sim card


This problem arises sometimes because the mobile is unable to read the SIM. May be you should fold a small piece of paper in the same size of the SIM and keep it on top of the SIM and then insert the Battery. I think this will solve your problem.

Sim card promblem


Hi,
How to correct sim card error / insert sim card

Procedure to follow


Step 1: Check the sim tray or sim seater to see if it it broken, if it is, replace it
Step 2: If the sim seater/tray is not broken, clean the entire terminal.
Step 3: If the sim seater/tray is not directly on the board, trace the broken led and solder it, or you replace the broken led with another sim tray.
Step 4: If it is still not working, change the battery and put a new battery, because a virus infected battery will always give such problem.
Step 5: Finally, if the problem still persist, then check the sim card and replace with another sim card if the former is bad because a bad sim card will always display such message as insert sim card or sim card error.

Take care

Phone won't turn on


Try inserting another sim card, if it doesn't boot up, then there's problem with the Handset. Clean the sim car interface and see if there's any twisted or tampered pins/interfaces, if so, try to straighten or else let the technician of the repairing do it for you.. good luck..
