🅰️ Please check the following items first:

① Confirm that the APN is set for the correct SIM/eSIM

If your phone uses multiple SIM cards or eSIMs at the same time, the most common issue is that the APN was set for the wrong SIM card.

Please confirm that the SIM/eSIM currently used for Mobile Data is the same SIM/eSIM where the APN settings were entered.

② Restart your device after completing the settings

After completing the APN settings, please restart your phone once and test the Personal Hotspot function again.

③ Recheck the APN information

Please carefully verify the following information:

✔ APN
✔ Username
✔ Password

Make sure all settings exactly match the information provided in the instruction manual.

⚠️ Important Notes

Due to the wide variety of smartphone brands, models, and operating system versions, the settings screens may differ depending on the device. Therefore, we cannot guarantee that the Personal Hotspot function will work on every device.

However, as of now, we have not received any cases where the Personal Hotspot function could not be used due to an issue with the JB SIM/eSIM itself.
