Yes, InmateAid's phone service works for inmates at North Platte Regional Correctional Center in Nebraska. If you are talking regularly with someone there, it is worth setting up because the savings add up quickly. The per-call rates at county facilities can be steep, and InmateAid's number brings that cost down to a more reasonable level.
On video calls, that is not part of the service at this time. InmateAid's phone line is voice only. Video visitation at county jails is typically handled exclusively through whatever platform the facility has contracted with directly, usually a service like Securus, GTL, or a similar provider. You would need to set up an account through whichever vendor North Platte uses for that feature.
For regular phone calls, though, InmateAid is worth it if the volume is there. The math is simple: estimate what you are currently spending per call, compare it to what you would spend with an InmateAid number, and if the monthly savings exceed the cost of the line, you are ahead. If you only talk occasionally, the savings may not justify it. But for families who talk daily or several times a week, the difference over a month is meaningful.
