I plan to make a wireless sms-sending device using this shield. I am based in Ireland and I wanted to check whether or not this could impact the shields ability to function as a result of different operational frequencies in Irish telecommunication systems etc.
(I am aware that i need to use a 2G sim card and the associated battery/antenna)
Any help would be greatly appreciated !

Re: FONA 800 Shield
All 2G networks should use the same set of frequencies.
