dual 5g internet use

Don’t forget my main reason for using two separate T-Mobile internet box’s is for additional bandwidth. That’s the only reason for using two of them. My concern is if this summer when the leaves bloom out on the trees my T-Mobile signal may degrade to unusable and am considering a Verizon 5g box if no interference is present between the T Mobile box and the Verizon box. The signal for the Verizon box comes from a different tower.
