GT-P7500 wifi +3G

Hello to one and all,

Being new to Android, I brought a tab black 10.1 from Malaysia gt-p7500 3G with wifi. It has a sim card instead of an sd card and I was wondeing if it was possible to swap the sim for a micro sd?
Also can the onboard memory be ugraded?

I have a 7500 as well, and no, its not possible to expand the memory on that device unfortunately.
