I have read this phone works on T-Mobile and US Mobile.
It also supports VoLTE. However, the Ting IMEI checker says it's not supported.
I'm using the X3 SIM, and I can "see" networks - T-Mobile 2G, 4G and have copied the APN settings for Ting. I did see the phone on the Dashboard briefly, but then it reverted to my old phone. Did Ting block the phone or is there something else that I can try? Thanks for your advice.
