Ask HN: Best solution for off-grid Internet access?

You can use cellular networks or satellite(Exede/HughesNet). With the cellular, you will get less bandwidth, but lower latency. Exede and Hughes satellites are in geosynchronous orbit so you will have ~700 ms latency, but higher throughput and higher data caps.

I've used both satellite and cellular options. I highly recommend cellular unless you have a specific reason why satellite would be better.

Both will make you pay a lot for additional bandwidth, though. I don't think anyone has "truly unlimited" anymore.

If you run your connection through a VPN it can be unlimited. I use 200-300 gigs a month through T-Mobile.

What does your VPN have to do with data consumption?

It allows you to get around the tethering limit and use unlimited data. T-Mobile inspects packets to determine regular phone usage vs tethering.

In my corner of the world (Eastern Europe), I pay less than 2 Euros a month for an unlimited bandwidth 4G connection (with telephony included). 4G only works in big cities ATM, but it falls back to 3g everywhere else.

what service provider do you use?
