4G Dual Sim Load Sharing RouterBoard

Sorry for the newbie questions. I promise I have tried to research on here prior to posting (I’m surprised I couldn’t find any similar discussions before).

As the title suggests there will be no wired WAN just two LTE modems setup with a load sharing algorithm (not bonding)

Would it be as simple as buying:

If you have any suggestions or any reference to other projects I would be grateful to hear of them.

Anyone have any resource I can research on?
