In some cases you may receive a CMS Error 500 error message from your modem. This error message indicates, that for some reason the modem was not able to deliver the message. This error can happen if:
The phone number you try to send your message to is invalid
There is no network coverage
You don't have enough money on a prepaid subscription
The short message service center of the GSM network operator is temporarily out of service
The GSM cell is overloaded
[對于開發(fā)人員]
出現(xiàn)這個錯誤，請將發(fā)送重試測試設為6.
[對于客戶]
解析--這個錯誤對于模塊來說是個未知錯誤,既同時出現(xiàn)了多個報錯
原因--最大可能是SIM卡欠費，有時日志中還會出現(xiàn)CMS error 0
解決方法--
1.拔掉設備電源，等1分鐘左右再啟動設備，
2.可以嘗試斷電后更換一張卡，并重啟中間件服務，再嘗試直接用中間件發(fā)送短信，一般能修復(最好更換不同運營商的卡）
3.以上方法都不可用時，進入超級終端，輸入 AT+CFUN=0回車，設備回復OK再次輸入 AT+CFUN=1回車，設備回復ok即可修復
