Topic: NO CARRIED error (Read 1 time) previous topic - next topic


It is my first post here.

I bought gsm shield from libelium-http://www.libelium.com/squidbee/index.php?title=New_GPRS_module_for_Arduino_(Hilo_-_Sagem)
I am using terminal 1.9 version to send commends.

I was trying to phone and send sms using  "Play" operator sim card. All the time I got  NO CARRIED error.
I thought that it is because of no aerial.
I got old sagem and remove aerial from it.

Firsty CSQ was 7.0 with aerial it is 17.99.
Then I changed sim card to "Orange"-it started working.

It is always perfect but,sometimes (CSQ above 19.00 ) CREG is not 1 and i can't use module.
Sometimes it can turn off without any reason.

Why it happends?Can i restart it in any way?
