A bit of background. I've been on the Unlimited plan for several years. For a bit over 2 years I used a Pixel (original) and was able to use the mobile hotspot without problem. Then my Pixel died.
I initially replaced it with a Galaxy S10e. But after a few days returned it and got a Pixel 3. Neither of these phones would allow me to activate/use the mobile hotspot. I would get an "Authentication failed" error. Since the same error appeared on 2 different phones it tells me it's not a hardware problem.
I consulted Verizon staff in store, who couldn't figure out the problem. They initially claimed my plan didn't include mobile hotspot & didn't believe I had been using it for 2 years. They only relented when I showed them my plan details which included mobile hotspot.
I tried Verizon support. Tier I ran me through the standard resets. Escalated to Tier II who did pretty much the same thing. Escalated to their "Network team" who eventually responded that I should turn on WiFi calling. Which proved they either didn't understand the issue or were too busy copy-pasting replies to care (FYI, you can't use WiFi calling & mobile hotspot at the same time. And if I had a WiFi connection available I wouldn't need the hotspot to begin with).
After a little internet searching, I went back to the store & got a new SIM card. Still getting the same error.
I don't have WiFi at my home. So I have relied on the hotspot for my internet connection for these past few years. It is EXTREMELY frustrating not having the hotspot. Does anyone have any additional suggestions?
Yes. I am able to use data, voice, and text. There is a strong signal. I can even stream video to my phone. It is just the mobile hotspot that fails to authenticate.
