 Bigger Bigger  Smaller Smaller  Reset Reset

Hello experts!!

I need help here. I have this link http://www.rhydolabz.com/learn/?p=1007&page=3. As you can see this page describes how to connect GSM SIM900 but I am using SIM900D and SIM900D has not same pins as SIM900. So what changes should I make in that schematic if I am using SIM900D instead of SIM900?

And also, what changes should I make in the programming if I am using SIM900D?

Thank you all

Why not ask rhydolabz? or the supplier of your SIM900D? or even a link to the product you are talking about (though if you had this you would be able to see the differences yourself)

I tried to ask the rhydolabz but I didn't get any activation email yet so I am unable to register there. I also contacted to their technical support but they didn't reply to me.
And for your kind information sir, it the forum of the official arduino. If you can't help then kindly don't suggest ways. We, already visited many links and then after we turn to the forums. And it is official forum so you experts must help and share knowledge if you know. Think, is it good that an official development site is asking their customer go and ask those who made that product even that product can be interfaced with the arduino?

SIM900D can be interfaced with the arduino so why do I contact SIM900D developers if I can get first hand knowledge from the arduino official forum.

sorry but you should consider that what are you saying.

Thank you.

I still need help
