Setting up a new APN network

I just installed the latest iode version 1.2 on my Sony Xperia XZ1 and the install directions were perfect for this phone. I am able to get to use my home WiFi perfectly but it’s not picking up my SIM card correctly. The provider is Ting and it shows as T-Mobile with no internet LTE access. I made a new APN for Ting using the setting Ting provided me with on their site, saved and re-booted but there is still no LTE.

Any ideas?
