Question about O2 Samsung SGH-E250 Cellular Phone
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.

Un-Clocked is temporary, allows free txt and calls for a few minutes.
Un-Locked from a network is what will allow you to use any sim card on your phone.

Do the SIM card and phone come from the same company, or are you using another providers SIM card on your phone?
Most phones in the US are locked so you can only use the provider that sold it to you. You may be able to request the unlock code if your contract has expired. Ohterwise you're stuck with the same phone company that sold you the phone.
