A:Answer Yes, you can, but it needs to manually set the APN to their custom "fp.com.attz", so it should be a hotspot capable of that setting. Probably one sold by FreedomPop or customized by/for them, will work. Be careful not to get a CDMA one, because FreedomPop also uses Sprint network. This SIM is for their service over AT&T. On their site you can filter products by "Network = GSM" like https://shop.freedompop.com/products/mobile-hotspots-and-modems/gsm and see if anything looks good. I personally do not like any of those, so I cannot recommend. The SIM card has the best price here on BestBuy.
