Which booster does cell as well as data

Our Maximium Signal Max Amp RV booster has worked well for us for both voice and data in a number of areas where our phones and hotspots indicate no signal or a very weak signal at best without it. But to clarify, the cell services are used for both voice, text, and data, although the different modulation formats used for standard voice and data are often on different "bands" or frequencies. That may account for differences in voice and data reception. Text sometimes works when voice on the same signal does not, simply because text uses a relatively simple data format that's easily error corrected on the fly compared to the much more complex voice formats. Error corrections add an unnoticeable delay to the reception of the text message, but that same delay would be completely unacceptable in voice calls.
