- **Insert into Phone:** Insert the small plug (Android A or B) directly into the SIM card slot of your mobile phone.

Operating Instructions
The UTHAI T13 allows you to switch between 20 SIM cards seamlessly:
- **Insert SIM Cards:** Place your SIM cards into the desired slots on the card changer board.
- **Activate a SIM Card:** To activate a specific SIM card, pull the corresponding switch towards the card slot. Only one switch can be turned on at a time. Turning on multiple switches will result in connection failure.
- **Switching SIM Cards:** To switch to another SIM card, first turn off the currently active switch. Then, pull out the small plug from your phone's SIM card slot slightly and re-insert it. Finally, turn on the switch for the new desired SIM card. The red LED light for the newly activated card will illuminate, and the signal will be displayed on your phone.
- **Hot Swapping:** The device supports hot-swapping, meaning you do not need to restart your phone when changing SIM cards. It typically takes about 5 seconds to replace a new card.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No signal or connection failure | Multiple SIM card switches are active simultaneously. | Ensure only one SIM card switch is turned on at a time. Turn off all switches, then activate only the desired one. |
| No signal after switching SIM cards | The phone has not re-registered the SIM card. | Gently pull out the small plug from your phone's SIM card slot a bit and re-insert it to force the phone to detect the new SIM. |
| Red LED light not on | Improper connection or device not powered. | Check that the FPC cable is securely inserted into the card changer and the small plug is fully inserted into the phone's SIM slot. Ensure the phone is powered on. |
| Device not compatible with phone | The card changer is not universally compatible with all phone models. | Verify that the specific model of the card changer (e.g., Android A or B plug type) is compatible with your phone model. Contact support if unsure. |

User Tips
- **Single Card Operation:** Remember that the card changer can only enable one SIM card at a time. Activating multiple cards simultaneously will lead to connection issues.

- **Broad Compatibility:** The device supports a wide range of network operators and card types, including domestic and international SIMs. Your phone's network compatibility will determine which networks you can use.
- **Model Specificity:** The card changer is not a one-size-fits-all device. Ensure you have the correct plug type (e.g., Android A or B) that matches your specific mobile phone model for proper functionality.
