I've never seen that rule in print or heard it from cabin crews, but I haven't witnessed many WeChat calls from airplanes...maybe in part because the bandwidth is often limited. I listen in on conference calls (with earphones) sometimes; the quality is usually (just) okay. I imagine an actual voice conversation would be frustrating.
