Error after entering PIN received via text

[pop_phone]

Then why am I being asked for a pin?

[pop_phone]

I tried to attach photos but it did not work. 

I have a iPhone 6 from Verizon. The messages+ app was not preinstalled. I had to download it.

After I close the app and reopen it after the rejected pin, it keeps trying to connect. Now it's telling me "data connectivity problem. Please ensure you have a stable connection." I have data access when this occurs.

Is iMessages turned off?  Is the Verizon Messages app set as your default app?  Do you have a stale cellular connection?  (At least for the initial setup - it works on wifi once it's set up)

How do I change the default messaging app on iOS 10?

I'm not sure - I've only had Android phones.  Hopefully someone more familiar with iOS can chime in?

Whether it is a similar path ... on my Android I go to Settings, Applications, then settings again, and I can set default apps for browser, phone, SMS, etc.

Yeah I don't think you can. I'll have to call Verizon to figure out what's going on.

Lets get to the bottom of this poip_phone. Which iPhone do you have? Have you been able to use Message plus before?

That is definitely alarming that you have never been able to Messages+, pop_phone. We definitely want to make sure you can choose what messaging application you want to use. It is normal for Messages+ to request a PIN when setting it up on the iPhone because it works similarly to setting it up on a tablet. Since you have been getting data connection errors when trying to set this up I wanted to check some settings on your device. Do you see Verizon Messages when you go to Settings > Cellular in the list of applications? If so, does it have data turned on with a green switch?
