Your EFS partition should back itself up during install but try creating a flashable backup of it before flashing the custom ROM and then flash it after you flash the ROM. Depending on how your phone was flashed it may be as simple as replacing the apn config file or adding specific apn's for voyager.
If the EFS route doesn't work try to copy the apn config file from your working ROM and putting the file in the ROM zip (system/etc) BEFORE
flashing the ROM.
Devices: Tmobile Wing (LOOONG GONE), [Huawei Mercury (dead), Evo 3D (retired after a long dirty life)] - Both Cricket - LG Optimus G Sprint Current ROM: ArtMod 5.0
and a few others in between.
