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!

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.

Was so happy with thus app at first but since using it my service has gone from excellent to some trash. Before I started using this app I could use almost 200 GB of data and my service would not slow down. But since using this app my service is extremely slow from the day after it restarts. I mean ridiculously slow. I tried uninstalling the app and it doesn't matter now somehow this app has ruined my service and I hate it.

You should always be able to switch back to auto mode. If you still have issues, it has nothing to do with the app and just your network issues.
