Help Roaming unable to authenticate on verizon


Oct 17, 2009
Whenever my phone-sprint hero roams (on verizon) and I try to make a call, I get the message "welcome to verizon wireless, we are currently unable to authenticate your phone" and can't make a call. Spent 2hrs on phone with sprint updated PRL but when I went back to the same location the same thing happen can't make call because of unable to authenticate. Anybody else having this issue?
I've been lurking for almost a year---hi everybody---and never felt compelled to respond until today...I had this same issue and many hours on the line with tech-support later, the plan was to ship me a new (refurb) device. That worked and I've not had any issues since. the annoying thing is that no one at sprint or in one of their stores could explain what happened, why it happened or if it would happen again. They also could not explain why the new device would work.

I had not rooted my phone or done anything sketchy to it. I bought it on 10/11/09, updated to 2.1 on May 19th, updated to .6 on June 4th and it stopped authenticating on Verizon's networks somewhere around June 6-8th. Just strange...

In any event, push the issue with advanced tech support and demand a new device. They had me reload 2.1, re-activate the phone with them, roll it back to .5 (the pre-June 4th version of 2.1) and NOTHING worked to get me back on roaming networks. all in all , wicked frustrating

I had the same problem, but I'm on Blackberry. Don't know if it will help, on Android, but I came here via a search, so others non-Android users might as well. Sprint knows nothing--the supervisor kept telling me that there were problems in the area, even though I could get to the Sprint network with #8899. It's amazing they don't know the basics as to how their network works.

What I finally did when I was back in a Sprint area was to :

1. Update preferred carrier list
2. Update profile
3. Run network diagnostics.

Hope that helps.
