This is a Tello APN Fix that I modefied to work for Tello when using custom roms like LineageOS. I tried it on Lineage Build 14, 15, 15.1 and 16 and it works 🙂
So if you having issues with Tello Data and stuff this should fix that.
The original was base on Freedompop APN Fix which I found here https://forum.xda-developers.com/showthread.php?t=2798619
Anyways I just putting here so I know where to get it lol
