The difference between sending MMS and sending WeChat

1. Send MMS, it costs 20 cents per message, I don’t know if the price has increased now; don’t download the APP, you can just receive text messages; text messages cannot send voice, only text and pictures;

2. To send WeChat, as long as there is a network (traffic or wifi), no extra charge is required; you need to download WeChat to receive and send; WeChat can send voice;
