This is a detect SM, it's supposed to be invisiable
Dear TP-Link Team,
I hope this message finds you well. Approximately a week ago, I purchased the TP-Link M7350 device and acquired a Vodafone data SIM card just two days ago.
While accessing messages on the device to review any notifications, I encountered an unusual message that prompted further investigation online. The message was sent from the number 10086 and stated:
"This is a detect SM, it's supposed to be invisible."
Further online research indicated that the sending number is associated with a Chinese telecommunications company, 10086. Moreover, it appears that the message content is related to silent tracking for device location detection, potentially jeopardizing user privacy by the Chinese number 10086.
The concerning and puzzling aspect is that when transferring the SIM card to a mobile phone, this particular message does not appear. It's noteworthy that messages are stored on the SIM card and only appear on the M7350 Wi-Fi device.
My inquiry pertains to whether this service is affiliated with your company. If so, could you kindly clarify the purpose behind this service, its usage, and the information it gathers?
Conversely, if this message is not associated with TP-Link but rather a third-party entity, I seek guidance on how to minimize potential risks and secure our privacy from such messages.
I greatly appreciate your attention to this matter and would be immensely thankful for your clarification and guidance regarding this issue, especially concerning user privacy.
Thank you very much for your time and assistance.
Respectfully, Amina
