For my hobby project I am looking for a cellular module with voice support. Because 2G and 3G are going to the end of life soon in the US I am considering 4G modules only. Ideally I expect world connectivity as well but this is not must.
Right now I am looking at WP7702 but I am not sure if this module has voice capability. The data sheet says depends on firmware so I am not 100% sure. Can anyone confirm if there is voice on WP 7702 please? Or recommend/advice another module(s) with voice particularly for the US market? Data speed does not matter. Thank you!
