cannot make a call on LTE (but WiFi) - error code 3302488

[halogen]

Hi Zoom support team, 

I recently changed my phone to iPhone 13 Pro from XR. From my old phone using the same USIM, the outbound or internal calls work well on both LTE and WiFi. However, it doesn't work on the new phone while using LTE mode. It displays an error code 3302488. 

So far I have tried following:

- check data enabling on the cellular network 

- re-installed USIM 

- restarted the phone 

- turned on and off the airplane mode 

- reset the network 

- re-installed Zoom App

None of them works so far. I cannot even find the error code 3302488. (refer to attached image)

Hey, @halogen –

Sounds like a particularly technical situation you have there. The volunteers in the Zoom Community might not be the best ones to ask – I’ve got Zoom Phone on my iPhone  X and iPad, but I wouldn’t have a clue where to start troubleshooting your issue, and I don’t see too many of us with Zoom Phone at all.
