No mobile data access on PPP

Actually, it's randomly worked at most four times for about 5min each time. I'm using Mobian, which I recently moved to the eMMC along with installing tow-boot to the SPI flash. I replace the sim card with a new sim card (both t-mobile). Mobile data worked fine using the old sim card in my beta PP and in a Samsung tablet, but did not work in my PPP. However, it was heavily scratched, so I got a new one to use in the PPP, hoping that it might help. So far the new sim has not made a difference.
Phone calls work well, as does text messaging. I read in a wiki that providing the carrier's APN was required in order to have mobile data working. For T-Mobile that is: Fast.t-mobile.com. I configured that using the Settings app under Mobile Network/Access Point Names. At this point I noted a difference between the PP and the PPP. When I edited an APN, the Settings app created a new "Broadband/mobilenet" APN. It does this every time I edit an APN. So now six APNs are listed, one of which is the T-Mobile APN (which is selected) and five of which are "Broadband/mobilenet" APNs . I would like to remove the other APN entries, but there is no provision for this in the UI. Does someone know of another way?
I also configured the SMS and MMS in Chatty.
I've spoken at length with t-mobile representatives. While they try to be helpful and understanding, they are not knowledgeable regarding non-supported phones and can only provide help via check lists that they are given. In addition, because the old sim works in my PP, it's very unlikely that it is a carrier issue.
If anyone else has had this issue or heard of it happening with other PPPs I'd appreciate any information that you can pass along. The PPP is a major performance improvement over the PP, yet if I can't get the mobile data working the performance improvements become unimportant. Mobile date is a core feature for me.
Been using my T-Mobile SIM in my PPP and when the OS is running haven't had any issues. I did need to create the APN, but after that haven't had any problems. Not much else is stable, but when the phone is running I haven't seen any issues with data. Probably worth giving the distro below a try just to see if it makes any difference?
