Samsung i9 108 mobile customized version can't send short messages, but can surf the Internet and receive short messages. The number of SMS center can't be saved, and PUD conversion method has also been used. I also encountered this strange problem today. Four days ago, after ROOT succeeded, he met Samsung i9 108. It's just ROOT. You don't need to brush your phone. Besides, the number of my SMS information center is set correctly. There's nothing wrong with it, but you can only receive messages, not send them. Finally, I found a way. I don't need to restore the factory settings or brush the machine. A very simple little way to recover in a few seconds. Ha ha! !
