Could modified carrier file cause cell tower refresh errors?

    What I mean by my thread title is that I used a guide on here to get a modified carrier file to allow built in tethering support. I'm now having service issues with the local cell tower in my area so yesterday ATT registered me to a different tower and it fixed the issue.

    Today I checked Signal app again and sure enough, it's back on the problem tower. 3G speeds are sucking again.

    So I'm wondering if the cell tower registration is strictly server-side or is it an actual file that's being sent to my phone which the modified carrier file might be interfering with.

    Can you perhaps unmodify the carrier file and see how it performs? That should solve your question :p
