<\/p>\n
For some people, airplane mode may be rarely used.<\/p>\n
But, who would have thought that this feature could actually fix some errors on Android phones, you know? One of them is an unreadable SIM card problem.<\/p>\n
I found this method on an overseas site called Technobezz, which also happens to discuss the topic we are discussing here.<\/p>\n
Besides that, I’ve also seen this method, shared by a member on my old Phone forum, and it works!<\/p>\n
Here’s how?<\/strong><\/span><\/p>\n\n- Press and hold the power button, then restart the cellphone.<\/li>\n
- Wait until the restart process is complete.<\/li>\n
- After logging into the system again, swipe down from the top menu ( status bar panel ).<\/li>\n
- Turn on airplane mode, then wait for 2 minutes.<\/li>\n
- Finally, turn off the mode again.<\/li>\n<\/ol>\n
Wait for the network to finish refreshing. Then the detection of the problematic SIM card will return to normal.<\/p>\n
<\/span>6. Change Network Settings<\/strong><\/span><\/h3>\n![\"Set](\"https:\/\/techmaina.com\/wp-content\/uploads\/2021\/07\/Set-Network-to-3G-4.jpg\" "\\"Change")
<\/p>\n
Phone network settings, we can actually change at will, you know.<\/p>\n
As previously discussed, provider interference is one of the reasons why the SIM card is not detected.<\/p>\n
Well, this disorder usually only occurs in one type of network. For example on 3G or 4G.<\/p>\n
The solution, we only need to change the Phone network:<\/p>\n
\n- Open the Dial application on the cellphone.<\/li>\n
- Then type *#*#4636#*#*.<\/li>\n
- Check Information 1 or Information 2 (SIM 1 or SIM 2).<\/li>\n
- Then please change the network type in the signal column.<\/li>\n<\/ol>\n
If so, just wait a few moments. Then the SIM card network that does not appear will be normal again.<\/p>\n
<\/span>7. Perform System Update<\/strong><\/span><\/h3>\n![\"Perform](\"https:\/\/techmaina.com\/wp-content\/uploads\/2021\/07\/Perform-System-Update.jpg\" "\\"Perform")
<\/p>\n
System bugs (errors) often affect many things. One of them is the detection error on the SIM card which makes it unreadable.<\/p>\n
The origins of this error vary. But usually the result of using it for too long. Yes, this has an effect, you know.<\/p>\n
The fix, you can try updating the system:<\/p>\n
\n- Open Phone Settings.<\/li>\n
- Then open the About Phone menu.<\/li>\n
- Then select System Update.<\/li>\n<\/ol>\n
Do an update there if it is already available. Then try to re-check the detection of the SIM card on the cellphone.<\/p>\n
<\/span>8. Reset Phone System<\/strong><\/span><\/h3>\n![\"factory](\"https:\/\/techmaina.com\/wp-content\/uploads\/2021\/07\/factory-settings.jpg\" "\\"Reset")
<\/p>\n
Reset Phone is highly recommended to try, because this method can help to fix errors that exist in the system, including problems with the SIM card.<\/p>\n
We can reset the Phone with the following steps:<\/p>\n
\n- Go to Android Settings.<\/li>\n
- Then go to the Backup and Reset menu.<\/li>\n
- Then select Factory Reset.<\/li>\n<\/ol>\n
Wait for the reset process for a while to finish.<\/p>\n
PS: <\/span><\/strong>Don’t forget to back up important data on your cellphone before doing a factory reset.<\/p>\n<\/span>9. Replace Battery<\/strong><\/span><\/h3>\n![\"Replace](\"https:\/\/techmaina.com\/wp-content\/uploads\/2021\/07\/Replace-the-battery.jpg\" "\\"Replace")
<\/p>\n
At first glance, it has nothing to do with it.<\/p>\n
I once had an experience, there was a cellphone that if it was inserted a SIM card it couldn’t read it.<\/p>\n
I’ve tried various things, even to reset and change the SIM card, but the results still haven’t changed.<\/p>\n
Then, finally, I tried to replace the battery. The result? The signal is lost, as well as the SIM card that does not appear in the system can return to normal.<\/p>\n
For those who don’t know, this can happen because the voltage on the battery is already problematic. This can affect other components such as Phone ICs.<\/p>\n
<\/span>10. ReFlash Phone<\/strong><\/span><\/h3>\n![\"Causes](\"https:\/\/techmaina.com\/wp-content\/uploads\/2021\/07\/Causes-of-Phone-Keep-Turning-Off-Itself.jpg\" "\\"ReFlash")
<\/p>\n
The most effective Phone repair that you can do yourself is to re-flash the cellphone.<\/p>\n
Through flashing, we can fix various types of errors on Android phones. Ranging from light to relatively heavy.<\/p>\n
The problem of the SIM card not being read as we are discussing here actually belongs to a rather heavy category.<\/p>\n
However, flashing can sometimes help overcome this problem, so that it is normal again.<\/p>\n
How do I flash it? Well, try searching again on Google about how to flash according to your cellphone type. Just adjust it, then there you will see the full tutorial.<\/p>\n
<\/span>11. Phone Service<\/strong><\/span><\/h3>\n![\"Solving](\"https:\/\/techmaina.com\/wp-content\/uploads\/2021\/07\/Solving-Overheat-Problems-on-Phone.jpg\" "\\"Phone")
<\/p>\n
Component problems such as damaged connectors -as discussed earlier- may sometimes be resolved by simply cleaning them.<\/p>\n
However, if that method doesn’t work, and the SIM card<\/a> is still unreadable, it means that the connector is probably damaged. It could be because there is a broken part.<\/p>\nComponent problems, in addition to connectors, IC PA on Phone can also be the cause. Even though it’s not 100%, this component is indeed identical to cellphone damage related to the signal.<\/p>\n
To find out and fix this problem, it would be better to take the cellphone directly to an authorized Service Center. A Phone technician will replace your damaged Phone component.<\/p>\n
Well, while the repair costs themselves are not too expensive, really. Estimates can be checked in the following table:<\/p>\n
\n\n\nComponent Type<\/strong><\/td>\nEstimated costs<\/strong><\/td>\n<\/tr>\n\n| SIM Connector<\/td>\n | Rs. 200 to Rs. 700<\/td>\n<\/tr>\n | \n| IC PA<\/td>\n | Rs. 500 to Rs. 15,000<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/span>Closing<\/strong><\/span><\/h2>\nThat’s the discussion about how to solve the unreadable SIM card. Many people are experiencing this problem, but still don’t know how to fix it.<\/p>\n Hopefully, with the tips above, your cellphone whose SIM card is not detected can return to normal.<\/p>\n If you have something related to this that you would like to ask, please leave a comment via the column provided below.<\/p>\n May be useful.<\/p>\n","protected":false},"excerpt":{"rendered":" His name is Phone, of course, it has a cellular network function.
