Dropbox "Two-step verification text message can't be sent", but my bank etc can send me texts????

[PD_OR]

When I login, I get the error "Two-step verification text message can't be sent".

But my bank, credit union & others can send me text messages. My phone number in Dropbox security settings is correct.

I've tried logging into Dropbox several times. Get the same error.

If I reset my password, I can get into my account, but if I logout & try to login again, I get the error message again.

How can I login to Dropbox without resetting my password every time???

Hey there @PD_OR - sorry to hear you're having issues with this.

Have you tried disabling the 2 step verification completely and re-enabling it anew at all since you first noticed this?

Let me know more and we'll take it from there.

[PD_OR]

Per your suggestion, I disabled 2-step verification, but when I try to re-enable it, it says my "carrier isn't supported at this time"!

However, the 2nd/alternative phone # I submitted to Dropbox DOES work. It's an identical model iPhone, and it DOES receive 2-step security texts from DB, using the SAME carrier as my phone!

Restarting all devices, clearing browser cache, etc makes no difference. 

Icing on the cake: Now DB says my account is locked for 24-hours! Too many attempts! Grrrrrr .....

This is indeed strange behavior, @PD_OR.

Would you mind turning off two-step verification and then setting it up again, but from a different browser or an incognito/private browsing window, to see if that makes any difference?

[PD_OR]

Today when I try to enable 2-step verification, I get this message (I've obscured my phone #). Kinda difficult to troubleshoot this issue when DB's security precautions make it impossible/impractical. I understand why this sort of thing is good practice, but a PITA when things don't work as expected.

I see, thanks for letting me know, @PD_OR, and thanks for your feedback here.

I'd personally try one more time from a different network/connection, but if that doesn't work, please give it some time and get back to us with the result tomorrow.

If it's still not working, let us know and we can send you an email, so we can investigate this internally together.
