Could this be used for LTE roaming? My parents live out in the middle of nowhere - no cell tower reception, but Starlink works so they have internet. I'd love to get them local LTE coverage for cell phone calls and text messages.
I used to live on the US-Canadian border where the ATT signal consistently was outcompeted by Rogers and Bell, leading to my phone essentially never working. This was ~10 years ago and ATT provided us some hardware that provided a 3G connection locally when connected to our DSL connection.
