My proble is i insert sim in mobile massage show please insert sim. my mobile model is m200 samsung

Hi, when a phone displays an insert sim message, it means that either the Sim card or the Sim tray where the sim card is inserted in the phone.

First, You can use the sim card on another phone to be sure that the sim card is still working properly. If the sim works with another phone, that means the sim tray where the sim card is being insert into the phone is bad and will need to be replaced.

You `can contact a skill personnel for help.

Have a nice day.

Sim card

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

I can't turn off my Samsung SGH - D880

Yesterday I also got the same problem on Samsung DUOS SGH-D780!
I found temporary solution how to drop this error message and run the phone normally, but after next reboot it often become again. I will ask Samsung tech. support about this, but now here is the emergency solution:

1. Turn OFF the phone (by removing the battery)
2. Move out all the SIM cards from the phone
3. Insert the battery again (BUT DON'T TURN ON THE PHONE, just insert the battery)
4. Insert a charging cable into the phone and insert the adapter in wall outlet

(then I see the loading screen for the short time and after that CHARGING icon appears)

5. After that turn ON the phone. It will start in no-sim mode.
6. Turn OFF the phone
7. Remove battery, insert SIM-cards, insert the battery.
8. Turn ON the phone

After that it gonna be work good until next reloading...

Cect P168 not dectecting My sim Card

The "insert sim" error is a common error. Usually it is caused from putting the sim in incorrectly.

Try this. If this is the one with the sim card ports that are on top of eachother than put the sim card in the port closest to the phone with the gold side pointing up.

Insert battery, turn on phone.

On the phone, go to the main menu. Tap phone settings. Tap dual sim settings. Tap to open sim 2. Go back to the main screen.

If that does not resolve go back to phone settings, tap dual sim settings, tap to open sim 1, go back to the main screen.

If this is the type of phone with the sim card ports seperate, insert sim with gold side down in either port. Go to phone settings, tap dual sim settings, tap open dual sims. Go back to main screen.

If this problem persists than either the phone or the sim is defective. Test the sim by putting it in a phone that belongs to the carrier the sim came from. If it works in that phone it is not the sim.
