I'm trying to figure out whether or not a SIM card is necessary to get 3G data working on a Verizon Note 2, Note 3, or S4 that is flashed to Boost.


What I've seen so far:

Three Verizon S4's flashed to Boost - no SIM card, everything working including 3G and MMS (MMS via 3rd party app).

Four Verizon Note 2's flashed to Boost - no SIM card, everything working including 3G and MMS (MMS via 3rd party app).

One Verizon Note 2 flashed to Boost - can't get 3G working w/o SIM card. Must install inactive SIM card to get 3G to work. MMS not working with or without SIM card (No MMS via stock or 3rd party app).

One Verizon Note 3 flashed to Boost - can't get 3G working w/o SIM card. Must install inactive SIM card to get 3G to work. MMS not working with or without SIM card (No MMS via stock or 3rd party app).


The results I'm seeing are inconsistent. Not sure if there was a missed step somewhere. Has anyone seen this before?
