Greetings - Have an unlocked AT&T LG V-20 working great on T-Mobile networks, except it will not authenticate for hotspot or any type of tethering. Do I need a custom APN?

When you double check your APN settings, do they match the ones on our BYOD T-Mobile data & APN settings page?

If the Wi-Fi settings for this network have become corrupted, you might be able to get up and running by "forgetting" the network and then reconnecting to it. You'll need to know the Wi-Fi password before you begin. 

1. Start the Settings app.

2. Go to your Wi-Fi settings. Where to find this depends on which Android phone and OS version you are using, but generally it will be found by "Wireless & networks" or "Connections."

3. Tap and hold the Wi-Fi network you are trying to connect to or tap the gear-shaped settings icon. Then choose "Forget this network."
4. After a moment, the network will appear in the list of available networks. Tap it and enter the password to reconnect.
