Nokia 5230 can't send SMS, how to set it on the mobile phone? thank you

Friend, you turn on the message on your mobile phone. Press the option -SMS- Message Center-to change the message center number to your local SMS center number!

Please call 10086 if you don't know!

Because I can't tell you the center number here, because the SMS center number in each region is different, so I'm afraid it will be troublesome and waste your time to tell you that your settings are wrong in the future!

You can call 10086 and ask where the number of the SMS center is, and it's OK!
