It's not working for me. I tried it but it isn't working. What do I do now?
Hello, you need to be sure that the sim card is allowed to send messages on your phone in case you are using a phone that uses dual SIM. Make sure that you have some airtime credit and outside that, all the message center numbers shared here is correct but am not sure why you are unable to send SMS on your phone, Alternatively, you can call your mobile network provider, MTN, GLO or Airtel, etc.
