At a Store that sells Sim's for iPad.Or service provider.
I have an ipad 3g and it has a Sim card, i don't know if it is a micro sim, it looks just like the Sim cardd in an iphone. There are two kinds of ipad and the ipad 3g does have one and the ipad wifi does not.
Only the iPad Wifi + 3G Model needs a Sim.
No it is different ipad has micro sim iphone does not and you have to activate it on the one you bought it with.
NO
If you have a 3G iPad, you will need a SIM card in every country. Wi-Fi only iPads don't have a sim card slot.
Yes. That is where the 3G account and provider information is stored. Micro sim is for ipad or mobile?
No, the iPad with 3G it is not SIM-Unlocked for multiple carriers, it is locked to AT&T. You may use Spirit jailbreak to unlock it and do as you wish with SIM unlock and so forth.
Push the SIM removal tool into the iPad on a vertical angle. The SIM tray should pop out, then pull it completely. A diagram can be found here: http://support.apple.com/kb/HT5163
There is only a SIM card slot in the 3G and 4G LTE iPads. The WiFi only models don't have a mobile radio, so a SIM slot would be useless.
S h i t
MicroSIM cards are supported in the 4G LTE models of the New iPad.
Phone numbers come with the SIM card, not the iPad itself, which may or may not be included with the iPad. If you have a data plan on your iPad, it will have a phone number, but won't accept calls
