YOGYAKARTA - Sim card problems are detected but no signal often makes mobile phone users feel confused and worried. Even though the SIM card has been read by the device, the operator signal does not appear, so users cannot make calls, send SMS, or access the internet. If you are experiencing this, it is important to understand the cause in order to find the right solution.
There are several factors that can cause sim card conditions to be detected but there is no signal, both in terms of devices, operator networks, to problems with the SIM card itself. Here are the general causes:
One of the most common causes is disruption to the operator network. This can occur due to system maintenance, technical problems, or infrastructure damage such as the BTS tower. If the disturbance is local, it will usually be repaired immediately by the operator.
If you are in a remote area or blocked by tall buildings, then your phone may not be able to pick up the signal properly. Locations such as basements, mountains, or forest areas can also cause signals to disappear.
Even if the sim card is detected but there is no signal, it could be that the SIM card chip has been damaged or cannot receive the signal properly. This is common in SIM cards that have been used for a long time.
Damage to SIM slots can also cause signal interference. Although the phone still detects a SIM card, damaged components can interfere with the communication between the card and the system.
Errors in network settings, such as selecting 4G only networks in areas that only support 3G or 2G, can cause the device to not receive the signal.
Bugs in operating systems or third-party applications that interfere with network functions can also be the cause. This can be exacerbated if the phone is never updated by the system.
How To Overcome Sim Card Detected But No Signal
After knowing some common causes, now is the time to find a solution. Here are the steps you can take:
The simplest step is to restart your phone. This action can update the system and restore temporarily disrupted network connections.
Enable aircraft mode for 1020 seconds, then disable it again. This method can help the phone search for signals from scratch and update the connection to the operator network.
Make sure you have selected the appropriate network mode. For example, if in your area only a 3G network is available, then select the "Prefer 3G" option or "Auto".
Try moving to an open or higher area. This can help your phone pick up a better signal, especially if you are in a closed or dense building area.
Enter another SIM card on your phone to find out if the problem is in the SIM card or device. If another card is working, it means your old SIM card may be damaged.
Turn off the phone and remove the SIM card. Clear the SIM card metal and SIM slot from the dust or dirt that may interfere with the connection.
Make sure your phone's operating system is updated to the latest version. This update usually brings bug fixes and network stability improvements.
If all the ways have been tried and the problem persists, you should contact the mobile operator customer service to get further assistance.
Facing a sim card situation detected but no signal is annoying, but that doesn't mean it can't be solved. By understanding the various possible causes and trying the solution that has been described, you can return the network function to its original state. Don't hesitate to ask for the help of a technician or operator service if the problem continues.
