Insert SIM Card Problem Fix

The "Insert SIM Card" problem can be irritating when it keeps on popping up even when a SIM card is actually been inserted into the phone's SIM card holder. It can sometimes be remedied by cleaning both the SIM card and the holder terminals with a cotton swab immersed in alcohol; most preferably 70% alcohol solution. Sometimes the holder is not tightly holding the SIM card causing the problem. This can be solved by padding up the back of the SIM card with a small sheet paper or any appropriate material enough for the holder to hold the SIM card tightly. Another way to fix the problem is by bending in the mid-section of the SIM holder cover.

Nokia 1110, 1110i, 1200, 1028, 1209 and all other member of the family of Nokia phones with USB ports similar to the ones mentioned earlier have the tendencies to experience the "Insert SIM Card" problem not due to a dirty terminals nor a loose holder but due to dirty, soiled, or oxidized USB port terminals. The fix is just as simple as cleaning the USB port terminals but make sure to remove the phone battery prior to the cleaning. Use a paper clip, a safety pin, or a needle with bended tip to scrape off the dirt between the port terminals and dip it in alcohol to wash it out.

The cleaning can be done without the necessity of disassembling the phone but if proper tools are available, disassemble the phone to clean the inside of the system connector, the one where the USB port, the charging socket, and the headset socket are located.

People may wonder how a dirty USB port can lead to the "Insert SIM Card" issue and guess what; it is not even included in the Nokia Service Manual. The fix was discovered accidentally and proven many times that a dirty USB port is indeed the source of the problem.

insert sim card


I'm not sure what the question is you are asking concerning a "sim card" but if it's How to put a SIM card in your cell phone you need a pin to put in the hole and it will pop open, However if your question is that your phone keeps telling you to insert a SIM card then you need to turn off your phone first and then go into the place where it's at and remove the SIM card and then put it back in and then turn your phone back on.

Samsung Geino, my sim is inserted but my phones keeps saying insert sim i carnt phone anyone blah blah help


Hi,when a phone keeps saying insert Sim card, is either the Sim card has problem or the Sim tray of the phone is bad and will need tobe replaced.

To confirm, Take the Sim card and insert it into another phone, If it still says insert Sim, that means the Sim card is bad, But if the Sim card works with another phone, That means the Sim tray of the phone is damaged.

Sim tray is located on the phone where you insert your Sim card in on the phone to make sure the Sim works with the phone.

Have a nice day.

I changed sim card, now they both display ''Insert SIM''


try taking out both cards and popping the battery on the phone.

Wait a few minutes and then turn the phone on with no card in it.

Turn it back off when it says no card found and insert the newer card and power it back up.

It seemed to keep a memory of the blank card.
