Reasons why SMS is not being delivered and how to fix it
There! are several possible! reasons why SMS may not be delivered! but they can be broadly divided into three categories! problems! with signal quality! problems with reception settings! and other problems.
These reasons can be on both the receiving and sending sides, but with the recent increase in identity authentication using SMS, it is more likely that the problem is on the receiving side.
On the other hand buy telemarketing data on the sending side, there are other things to be careful of in addition to the above three, but first we will introduce three of them: “problems with radio wave conditions,” “problems with receiving settings,” and “other problems.”
SMS uses mobile data communication rather than an internet connection such as Wi-Fi, so if the signal is weak or you are out of range, SMS may not be delivered.
You can check the signal strength on your smartphone or mobile phone using the icon at the top of the screen.
Although it varies slightly depending on the model, the mark that indicates the signal strength is a mark with four bars lined up that get longer as you go to the right, or a triangle with acute angles on the bottom left and top right.
- Airplane mode is off
If the radio wave exposure to high temperatures helps reduce the impurity content icon is not displayed and an airplane icon is displayed, “Airplane mode” is on. Airplane mode is a function that turns off wireless communications such as the Internet and telephones, and when it is on, you will not be able to receive SMS.
If you see an airplane icon, turn the setting off.
You can change the airplane mode settings by swiping down from the top of your smartphone screen and tapping the airplane icon.
Check the signal strength
If the signal is dating data poor, move to a location with better reception.
If there is no change even after moving, try turning on the airplane mode as mentioned earlier and then turning it off again, or restarting the device. By blocking the signal, the device will search for the signal again, which may improve the signal.
