LG G5 wont allow me to make phone calls on LTE

Hi all,

pleasure to be here, I bought a used LG G5 because I needed a phone to connect via Tello (Sprint), long story short I was able to connect the phone with Tello but my issue is that if the phone is on LTE I cant make any calls/texts, I get an error message saying: Mobile network is unavailable but internet on LTE works fine. if I switch from LTE to CDMA (3G) I'm able to make phone calls/Texts but I'm not able to user the internet. Tello it's been working with me on this issue since December, I've been researching on this issue all over the internet with no luck. today tello called me and told me that the issue is on the phone and that I should take it to a repair shop, I'm not sure what the repair shop will do to fix this so that's why I'm here looking for your PRO help. any help is appreciated.

I would like to verify that you're not a Sprint customer, correct? Tello uses our spectrum, but they're not related to Sprint in any other way. Any troubleshooting would have to be based on their network, and we need to go through them.
