Why can't I send text messages on my mobile phone? What's with the SMS center? I am now in Bijie, Guizhou. Come on, everybody, 3Q.

Hello, landlord, I have also encountered this situation! 1. First, you must make sure that your SMS center number is correct. 2. If you can't send it even if the SMS center number is correct, you can call 10086 for manual service consultation! That's all I know. Hope to help the landlord!
