Ultimately it means just as it says, the module you've attached, does not work with that phone.
If you'd like further help you will need to tell us the make/model of your phone, and the module you're trying to use with it.
I am having the same issue. I was talking on the phone, felt a buzz and then I lost my call, got the error message "The module you've attached doesn't work with this phone or isn't inserted correctly. Please use a Verizon-compatible module and check that it's inserted correctly."
I have not / was not / did not "attach a module" or anything else during the phone call. Now the phone will not reboot no matter how long I hold the switch to restart. LOCKED. Need help understanding why my phone is obviously CONFUSED! and this is my only phone so I am stuck.
We apologize for the delay, and we are here to help. I know how much we rely on our phones for everything, and getting this back to working condition is our goal here. Can you tell us the make and model of the device?
On the chance that it is the LG G5, here’s how to remove and re-insert the battery.
If it’s another make and model besides the LG G5, then do not attempt to remove the battery.
Hello BridgetMadonna, we're concerned to learn that you're also having this issue, and we're here to help. When did your problem start? What make and model device do you have?
