1. Please use the standard card access password to access the card.

Non-standard pickup pins may not match, so Cato cannot be removed. Please use a standard card-taking needle, insert it vertically into the top pinhole, and press it inward with a little force. When the card holder pops up, take it out. Please pay attention to distinguish between the top pinhole and the microphone hole.

* Note: 1) How to get the card can be found in Settings-System Management/My Equipment-Customer Service-User Manual-Overview of Mobile Phone and Quick Start-Installation and Preparation.

2) If the card fetching needle is lost, please do not use toothpicks and other fragile items to fetch the card, so as not to damage the machine.

2. Please confirm whether it is caused by inserting the microphone hole by mistake.

The top pinhole and microphone hole of some models are at the bottom of the phone. Please locate the top pinhole and try again.

* Note: Please refer to the user manual for the location of microphone holes and top pinholes (enter Settings-System Management-Customer Service-User Manual-Overview of Mobile Phone and Quick Start-Brief Introduction of Mobile Phone Appearance).
