I did, no luck
I've tried using LTE only with Network settings and sometimes get LTE to stick but no cell signal available then.
Kinda pissed right now, because I did use *228 and that might be it. It worked fine on stock and AOSP for a long time but I switched phones with my wife and did *228, got a new SIM card and worked but tried *228 to update roaming
Check that out
