GSM Shield Dont Work

Hi,

I'm a newbie here so please bear with me :slight_smile:
I've been following the installation procedures of the GSM SHIELD to my Arduino Mega 2560.

Then I run the Sample Programs for GSM.

It stops with this line:
gsmAccess.begin(PINNUMBER); --It Literally Stops... I've been waiting for 5 minutes and still do not reply.

So I try the other programs like Band Management
This is what it returns :

Restarting modem...
Modem restarted.
Unrecognized modem answer:
Current band:
Want to change the band youรข??re on?
Select band:
1 : E-GSM(900)
2 : DCS(1800)
3 : PCS(1900)
4 : E-GSM(900)+DCS(1800) ex: Europe
5 : GSM(850)+PCS(1900) Ex: USA, South Am.
6 : GSM(850)+E-GSM(900)+DCS(1800)+PCS(1900)

My SIM does no have PIN.

This GSM Shield is new. Previously, before my WiFi shield get to work I needed to first update its firmware, but I failed to found how to upgrade my GSM Shield.

Is there anything I've been missing?

Thanks in Advance

Sorry for this post... I found the solution...
p10 is connected to pin2 and the shield pin2 must not connect to the arduino mega

Thanks :slight_smile:
