I'm trying to reconfigure my phone, which was a Verizon phone for Consumer cellular. I purchased it new and unlocked two years ago from Sears, and it worked with the A&T settings, but two weeks ago I lost voice calls, but the internet works with mobile data and I can send texts.
I tried to switch to the T-mobile settings and I get voice but no internet (without wifi).
I think the problem is that I can't seem to change the MNC setting from 410 to 260. It either deletes the APN profile or it refuses to change the item.
How do I set the MNC setting for the t-mobile profile to 260?
Here is Consumer Cellular's website on APN settings.
Again, if I change MNC from 410 to 260, it just deletes the profile when I hit "save", or it doesn't register the changes and leaves it at 410.
