Why can´t I use my Hotspot on LG k8V

[Android Central Question]

I tried to use a hotspot on my LG K8 V, and I could not, because sim card is from another carrier, some people tells me I have to root my phoneand instal an apk to solve it. The phone is unlocked. When I turn hotspot a mesage appears on my phone, this sim card is not from verizon, and so on. Please Help me
