Hi, I’m using a SIM868 DK.
I was using my own simcard to develop the code but I have decided to buy a new one to use it only for this project. Both simcards are from the same provider so the configuration should be the same.
I was trying the new SIMcard but for my surprise when I was doing the SAPBR configuration I received “operation not allowed”.
The secuence and the answer are:
AT+SAPBR=3,1,"Contype","GPRS" OK AT+SAPBR=3,1,"APN","orangeworld" OK AT+SAPBR=3,1,"USER","orange" OK AT+SAPBR=3,1,"PWD","orange" OK AT+SAPBR=1,1 +CME ERROR: operation not allowed
As I said, this simcard is new. I thougt that maybe the simcard was disabled, due sometimes it’s necessary enable the simcard with the phone, but my provider sais that the simcard is activated.
Any idea could help.
Thank you so much
