Sim card in my ipad

[claranieto]

Today while trying to access the internet my iPad said it didn't have a sim card. I took off the cover and don't even see where one might be installed?

If you have a wifi model, there is no place for a sim card. In the States, it is inserted when the iPad is purchased.
