I can receive the phone call. When I dialed out, I got CEER: Error 31 - Normal, unspecified. I checked network, signal strength. It seems everything is good.

What can be wrong? Please help.

That suggests that your call successfully reached the called party, but the called party hung-up the call.

You need to check what is actually happening at the called number!

What is the called number - an analogue landline? GSM? ISDN? or what :question:

Have you enabled the +WIND 5 and 6 indications?

WIND is turned on. It is a GSM phone call.

+WIND: 6,1

Please help. Thanks again
