Currently, my ideal setup is GLinet Spitz X750, with the LTE modem swapped out to a MC7455 for maximum compatibility (for mpcie slotted cards) with the world's LTE bands. Then run GoldenOrb's ROOter. The x750 has integrated dual band simu WiFi, and has an integrated slot and pigtails for the modem. Since I travel a lot, I can power this entire thing off of an Anker USB power bank.

Today, you can go the route of: 1) OpenWRT with ModemManager, 2) WiFix's ROOter, or 3) GoldenOrb's ROOter. Personally I like GoldenOrb's ROOter because it has a nicer UI interface that I can access from my phone. You can SSH into it and hack the scripts to get things to work exactly how you want to as well.

Shoutout to the GLinet team, they actually listen to feedback.

Curious how you use this on the road. Is it basically a hotspot?

Quite expensive ($120?). My setup consists of a RPi Zero (20 € new), LTE stick as in this post (29 € used), USB power adapter (5 €), micro USB to USB (2 €), so in total only around 55 €, minus lots of fun setting it up (priceless). Not sure the RPi Zero is the best option here in terms of speed, but it works well for my purposes.

Edit: Looks like the RPi Zero maxes out at around 35 MBit/s.

I been wanting to try the SDR [0] approach, but knowing OpenWRT can do it is thrilling. What LTE release do they support?

Also, I see ROOTer supports Android devices using tether. I am curious if this is better than PdaNet+

If you want none of the fun, a rooted dual SIM smartphone does all that. I've not had trouble finding prepaid SIMs that would not work via Hotspot.
