How to Fix a SIM Card Error on a BlackBerry

By Alexis Kezirian

If a BlackBerry is dropped to hard, exposed to water or malfunctions, the screen will often display a message reading "SIM Card Error." The phone will not operate correctly on the radio path or network until this is fixed.

SIM Card Has Shifted Out of Place

Step 1

Remove the back cover of your phone. To do so, you will have to press down on the silver latch while sliding the cover off toward the top of the phone.

Step 2

Remove the battery from inside of the phone. Be sure to place it somewhere where it will not be damaged. Locate a silver hatch; this is where the SIM card is stored.

Step 3

To undo the silver hatch, slide it in the direction that says "Unlock." Then, flip it upwards so that only one end of it remains attached to the BlackBerry. Carefully remove the SIM card.

Step 4

Replace the SIM card after a few seconds. It should fit back into its place in the exact same way you found it. Lock the silver hatch by laying it back down over the SIM card, and then sliding it the opposite way you had unlocked it before (to the side that says "Lock"). Put the battery back in as well (by fitting one end at a time). Replace the cover (make sure the silver button latches).

Step 5

Turn the phone back on. The "SIM Card Error" message should be gone.

Fixing a Simple SIM Card Error

Step 1

If the SIM card has not been moved out of place, the remedy for a SIM card error is relatively simple: Power your BlackBerry off, then power it back on.

Step 2

Hold down "End Talk" (two buttons to the right of the Trackball) for five seconds. The screen of the phone should say that it is shutting down.

Step 3

Wait for 10 seconds. This step is not completely necessary, but ensures a full system reboot.

Step 4

Turn the phone back on by hitting the same "End Talk" key. You do not usually have to hold it down this time. The phone should power back on without a "SIM Card Error" message.

Tips & Warnings

  • Ensure that all information that may be lost if the phone is turned off has been saved before beginning this process.
