Hello:)
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?
