Is using JMP+Cheogram a more secure and private method of phone and texting, than using a carrier?

What the title says. I'm trying to discern if using a number acquired and served through JMP for phone and text, versus a mobile carrier, provides a better data security and privacy experience.

On the one hand I wouldn't be subject to the almost yearly data breaches that a number of the carriers experience, nor their potential snooping. However on the other, I'm not sure if using JMP and Cheogram actually provides any increase in privacy or security on that front?
