A lot of people in the US aren’t as used to using hotspotting as they could be, because of how many of the cell phone carriers here control so many features of the phone that they shouldn’t be able to control.
Many carriers simply don’t allow hotspotting. They sell you a phone with that feature locked in the operating system and you can’t then use that feature of the phone that Samsung or Apple intended you to have on their non-carrier-specific phones.
Other carriers meter and control hotspotting. They charge extra for it and even tell you that you may have (for example) 25GB of data for use on the phone and another 15GB of hotspotting data. It should be none of their damn business how you use the data you pay them for.
It’ll be nice when hotspotting data works on the Librem 5. The carrier can f-off and can’t stop you from using what you buy from them then, however you want to.
In most cases, you can get around the carrier’s hotspotting lockouts by either rooting your phone or by using Foxfi from the Play Store.
