If I open the dialer manually then paste the code it works. If I paste the code into the dialer that the app opens automatically it is treated as a voice call which fails and doesn't return any info.

Automatic carrier selection for Google Fi only allowed me to make calls over wifi. A few minutes with this app to switch to T-Mobile and my phone is no longer insisting all numbers I dial are incorrect. Thank you!

They need to add instructions for the people that don't understand you have to paste what the app adds to your clipboard into the dialer. But that's not why I am giving 3 stars. Why does it still have Sprint's network as an option when they were bought by T-Mobile? Need to update that ,it's not a good look.
