Signal jammer knowledge-quick questions and answers

1.The shell of the mobile phone signal jammer will get hot after working for a period of time. Will it damage the machine if it works for a long time?

The mobile phone signal jammer may get hot after long-term use, but this is normal. The design uses aluminum alloy heat-conducting strips to facilitate heat dissipation and ensure long-term stable operation. Therefore, the heated shell will not damage the device.

2.How to check whether the mobile phone is blocked?

When checking whether the mobile phone is blocked, it is important not to rely solely on the signal grid number displayed on the mobile phone. The signal grid number is sometimes misleading and does not accurately represent the current communication situation. Instead, calls should be made intermittently. You can try to call a local toll-free number or landline. If the call fails, it means that the mobile phone is still within the interference range. If the call is connected, it means that the interference range will not affect the mobile phone.
