Dear all,
I am traing to send SMS.
I red this:
Make sure the proper GSM band has been selected for your country. For the US the band must be set to 7.
To set the band, use this command: AT+SBAND=7
As, I am not in US, how can I know the band for other country?
For now I need for Switzerland.
But there is a lits of countries?
Thank a lot
Cheers
