I'm going to suggest you try a test....before you leave download textnow and call forward your pm phone # to the Canadian phone # you choose for textnow. In theory unless your phone/Sim card connects to the 2G network your call forwarding will remain in place (if it connects to the 2G network it will default back to your pm voicemail) allowing for your incoming pm calls to be recieved on your phone thru your textnow app. This would ensure the reliability of T-Mobile's 4G LTE network rather than their 2G network which is location dependent and has reception and connectivity issues when traveling (like driving etc...).
Setting up your voicemail greeting on both textnow and changing your pm greeting to include your textnow phone# so your contacts will have that option for contact and recognize any incoming calls/texts originating from that phone # would be helpful as well. Since you will recieve incoming pm SMS texts regardless (no US Roaming add on is needed for incoming SMS texts) you can opt for just a US Roaming data add on rather than the bundle. MMS texts can be sent/recieved with just a US Roaming data add on but will count as usage against the mobile data as will calling minutes on the textnow app when you are not connected to wifi (0.5mb/1min).
If you just have a US Roaming data add on this could ensure you won't connect to the 2G network (cancelling call forwarding). I'm mentioning this because another member who did some testing for us ( @DennyCrane ) also has a pixel 5 and his phone was unable to switch to the 2G network mode to use the 2G network for voice calls rendering that feature of his US Roaming add on useless and an unnecessary expenditure. I believe @hairbag1 mentioned he successfully used just a US Roaming data add on and textnow and kept his call forwarding intact while traveling in Washington state.
If you have the time to report back any of your experience with using your US Roaming add ons or any testing you may do with them we would greatly appreciate it. Just a reminder that the "clock" on the (now) 15 day US Roaming add ons starts immediately after purchase (15×24 hours=360 hours til expiry). If you will be purchasing another US Roaming add on after expiry please note the time of purchase as the old 10 day US Roaming add ons required a 24 hour wait time to repurchase the same add on and we are curious if the same holds true for the new 15 day US Roaming add ons? If so purchasing the same one again during that 24 hour period requires the assistance of customer support.
Enjoy your trip and Stay--Safe!

I noticed the mention in the small print that data speed is the same as your home plan when roaming in the US but it is to my understanding that pm has no control over throttling on their roaming partner's network so a pm customer with a "3G" plan would have the same data speed that T-Mobile offers all of its customer's on their 4G LTE network (avg. speed 25 to 35mbps) after the first 48 hours? I think @sheytoon mentioned this previously?
