I did not notice this issue when I was on JellyBeans 4.3 Rom. I'm currently running a 4.4.2 Eclipse Rom. I've tried the MI9, MJE, NC2, and NC4 modem all with the same issue. I beginning to think that it's my SIM card that has gone bad. I'm having a new SIM ordered so I can replace it.
Does anyone else have anything that I could try as troubleshooting?
I'm not sure if it's the SIM card that is causing your problem. Just curious....what network mode do you have selected? Global or LTE/CDMA?
If you have "Global" selected, you may want to switch to "LTE/CDMA" and see if that helps.
It could also be EclipseRom. I love the features and looks of AOSP, but my own phone always seems to have a weaker radio signal when I'm on that Rom as compared to true TW Roms.
You may want to further troubleshoot by flashing a different Rom to see if you still get the same LTE drop-offs.
