Geeetech

It seems ok now.
I haven't got a clue, what was wrogng.
I may had to wait a bit.

Thanks, again.

I've ordered and got the shield and not working.
The green led is blinking coninously (over 2-3 minutes), I've tried another antenna and checked the contacts.
I have another one and it's works perfectly in this configuration (same arduino, same SIM, same code).
If you have any idea please tell me ...

Here are the high resolution photos.

I've received GPRS/GSM shield but it's not working. eorder0612 suggested I should send a topic to here.
Have anybody some suggestion or clue?

Thanks

Istvan
