As for my Umidigi, I only use it as a media player while working out and use the Moto G Pure as my phone. Hopefully things stay working.
Thanks for the info.
In the plan subscription in your account, 3G or 4G or 5G refers to the speed. All plans have access to all available network frequencies, the plan details determine the maximum speed throttle. Ie on your 3G plan you could be connected to 5G but the speedi is throttled to 3 mbps max.
On your phone status bar 3G or 4G (or 5G if your phone has the right frequencies and you are connected to a 5G tower) indicates what connection your phone is using. If the phone is not VoLTE capable or not on the white list, calls are routed through the 3G network. Ie your data is on 4G/LTE, you call someone or a call comes in, the phone switches to 3G. Depending on location and phone this is totally fine for the next little bit until 3G is discontinued, or it could make calls a pain to totally unusable.
If your Moto G doesn't have the specific tag, watching the connection tag during a call would indicate if you are on VoLTE. If the status bar says LTE while you are on a call, you are using VoLTE.
If you are heading to the US, where 3G doesn't exist anymore, phones not on the white list might still be able to call by dropping down to the T-Mobile 2G network where it's available. However, to take full advantage of the roaming plans or add-ons, a white listed phone is definitely the way to go, unfortunately.
Found this screen shot from my Umidigi (on the first day it was active on VoLTE), this account is on a $15 3G plan.
