I've been struggling to get this phone to IMS Register and to get the voLTE to operate on Mint Mobile.
This phone is spec'd to be US LTE Compatible. It has all of the necessary bands.
I must say, I have a $3/Mon T-Mobile SIM in this phone also and it doesn't have the problems that Mint has.
When making voice calls on Mint it switches to GPRS, UMTS or HSPA+. Never 4G LTE. I have also tested Mint on a Nokia 6(TA-1025) and it Registers, and voLTE has never failed, but it's only a Single SIM phone.
