Ask HN: Prepaid mobile hotspots with no expiration? 3G, 4G, or LTE.
I want a mobile hotspot so that I can browse the Internet on my MacBook while riding the train/bus/whatever. I want to prepay for data transfer with no expiration. e.g., pay $50 for 5gb of data transfer that I can use whenever I want.
From my research, it seems like the major carriers all offer hotspots, but either confine you to a monthly contract, or offer prepaid plans with expirations. So yes, you can pre-pay $50 for 5gb of data, but you need to pay it again the next month even if you did not use all 5gb of data.
It seems like the best solution is a USB modem with a SIM card slot, coupled with a prepaid data plan loaded onto a SIM card. But this raises many questions: Which USB modem? Which bands should it support? Where to buy the SIM card?
I imagine this is a problem someone on HN has already solved. But the literature online is surprisingly sparse. So... any recommendations?
