Hey guys,
I’m thinking about new project for a while.
I want to add to the project internet over GSM, Bluetooth and SD card.
I’ve seen many modules that shows GSM+SD SLOT, but when I looking for the module for purchase it’s probably show a lower version of it without the SD SLOT.
It would be nice to have BlueTooth+SD SLOT or GSM+SD SLOT as combined module.
BTW: is it possible to use the Bluetooth module with the GSM module?
Thanks!

And quite possibly not. I have never seen a GSM module with SD

You could put them together on a proto shield, all three if you like, but there may be a trap there. Bluetooth may not work so well hidden down in the bowels of an Arduino, and you may be better off with it on flying leads.
BTW: is it possible to use the Bluetooth module with the GSM module?
This is quite feasible. If your Arduino has only one hardware serial port, you can have GSM on software serial and Bluetooth on hardware serial.
You should ensure there are no nasty surprises with a GSM module on your phone service.
As you can see here, it’s a module with sd slot, what do you think about it?
So according to your suggestion, the Bluetooth module should be separate to get better signal range?
I don't think very much of it at all. That slot is for the SIM.
I thought I was doing a smart job in the picture below. Bluetooth was neatly hidden under two shields, one of which is shown.
Range was hardly the word, it didn't work at all but was fine when I dug it out and put it back on a ribbon.
Please look at this:
OK, it looks like there is a microSD in the corner, which is pretty useful. I've never seen a shield like that before. You still need to check that you can use it on your networks.
What do you mean by “using your networks?”
I mean: Is it compatible?
I don't know much about this and only raise the caution that you need to before you buy.
These devices are defined by their SIM900 chip and I understand they will not work with 3G networks, which means they will no longer work in Australia. That doesn't mean they won't work if you are somewhere else but, particularly if you have been getting some notes from your network about needing to upgrade your phone, I think you should check this.
thank you, I've checked it and its seem to be the SIM900 is not fit to my country,
i've bought SIM900A and its should be work with couple of the 2G network inside my country
