You will be able to use mobile data while you are in the USA.
As for calls and texts, these are hit and miss (not officially supported) as stated here by Fizz: https://fizz.ca/en/faq/why-do-some-calls-and-texts-when-us-not-work
If you have access to data or wi-fi, you can use any of the VOIP or chat apps available to make and receive calls.

If your question is: Are VoLTE calls (Calls on 4G LTE) ready with Fizz in the USA, the answer is PROBABLY NOT.
If you want to know if calls will always work everywhere in the USA, the answer is NO.
Calls still work on old 2G or 3G networks when using T-Mobile roaming provider in many areas, but not everywhere. If 2G or 3G networks are not available, you will need data, not minutes, and a calling app such as Skype, Google, Duo, Textnow or other app to use the data 4G LTE networks for calls.
Outgoing calls are easier to setup. Google Contacts app lets you choose your calling app: your phone app (may not work) or data calling Skype or Google Duo. Skype can call to landphones but costs 3.3 cents per minute whereas Duo calls mobile phones you normally call ( friends essentially) and are free.
The problem is with incoming calls, as traditional calls may not get to you because of missing 2G or 3G networks.
A calling solution post should probably be started to help people getting along with this temporary networks disturbance in the USA.
