Anyway to prevent cellular radio shutting off on low battery?

[Sim-X]

I did some searching and couldn't find an answer. I know the cell radio shuts off when the battery gets low but sometimes I don't notice it because I will check to see if the phone is on and won't notice the radio is off. I would much rather just have the phone shut off all together. Is there a way to disable the radio shutting off?

thx
