tablets with 3G

Hi,

New to the whole 3g and 4g availability. My question is, if I get a tablet with just wi-fi availability will I be able to add the 3g availability afterwords or not? Basically, is it just a service or is it a component that is on the tablet itself?
Any help will be appreciated.

It's a component or small card in the device.

As to 4G, given the worries about GPS interference be sure you arrange for a full refund if they fail.

Thanks

Since it's a component, I guess I would need to buy a device that comes with it, right? Is there no way to just add a 3g or 4g component later? Anyways, thanks for the reply!

Then the answer must be?

That the maker will have to offer these devices? So far, TABLETS have no user interchangeable cards excep for a memory card.

Yes and no...

You can't physically add a 3G or 4G radio to the device but you can purchase a mobile hotspot like the MiFi 2200 and subscribe to a data plan. You could also buy a smartphone capable of sharing a limited amount of its data bandwidth via wi-fi.
I pay $35/month for 3GB of data that I share between an iPod touch and an iPad. It saves me about $15 over the cost of a $30 unlimited data plan for a smartphone and the extra $20 tethering fee to share with the iPad.
