Hey there! Congrats on receiving your phone :)
Your hotspot ability is already enabled from our end, you just have to turn it on in your phone's settings. If you're receiving any sort of error, please try the following:
1. Open up the phone's settings and look for "System Updates"
2. With your Wi-Fi turned on, complete the "PRL" and "Profile" updates, reboot the phone and try the hotspot once again.
