Hello! Thank you for your question. I will be assisting you today.
I'm sorry about the issue. What's the model of your Acer Iconia Tab 7, such as B1 or A100, etc.?
I think your Acer tablet has a slot for microSD card, which has smaller size than SD card. Have you tried with a microSD card?
Iconia Tab 7 A1-713/A1-713HD
Thank you. Do you see a microSD slot on your Acer tablet?
(i) Iconia Tab 7 A1-713/A1-713HD (ii) This particular model does not have external CD slot - confirmed by vendor via telephone.
The upper segment of the rear is removable, and reveals the SIM card and the microSD card slots. The cover is a thin strip of plastic that flexes easily and is very flimsy.
Let me provide you a couple of images:
See the last image, can you slide out that part?
Yes CD and SIM slots successfully revealed - thank you.
