I've tried several times to permanently unlock my phone with the app. I paid for it fully before I left the store. I've tried different towers, WiFi hotspots, towns, and times. Every time I get "Server not responding." I called customer support and they said they would email an unlock code in a day or so. Then I get the email... This device can't be unlocked with a code, use the device unlock app on your phone.

Gotcha -- that is definitely a lot of attempts! Have you been using the device on the T-Mobile network since you got it this summer? If the answer to that question is yes, then you'd definitely have satisfied the usage requirement if you have a postpaid account and it's in good standing. If you're trying this on and off of Wi-Fi and getting the same result, then here are the basic troubleshooting steps we'd recommend before we'd encourage you to Contact Us:
- Turn Wi-Fi off.
- Verify you have at least 2 bars of 3G/4G/LTE signal.
- Check for app updates, and install them.
- Clear the app cache.
If you've confirmed your eligibility against the link above, and tried these steps without success, then we'd want you to reach out for assistance so that we can try to get to the bottom of this. The app is definitely the only way to get one of these devices unlocked, so I'm sorry to read that we previously took up your time filing a request. If it's an option for you, then I'd recommend working with our T-Force team on FB (via Message) or Twitter (via DM) -- you can link to this thread since we've already discussed so much here!
