I'm posting in the iPad forum because ultimately, the data will be used for an iPad. Mods may move as necessary. I've seen claims in posts on this site, that they had a 'hotspot mobile' and the data was unlimited and 20 dollars a month. I asked which carrier but received no reply. So I'm posing the question to the group here. Is there any kind of data plan offering a SIM card or built in CDMA at all that is designed for a mobile hotspot that offers truly unlimited data at any price? I'm in the US. So obviously that is where I would buy.
