How many text messages can a card send every day?

There is no such thing. It's all a lie. Taobao can't sell unlimited products. If there is, people will use it for themselves and return it to you. SMS sending companies all use our ordinary anonymous ordinary cards. Just send cats in bulk, keep sending them, send as much as you can overdraw (that is, don't stop if you owe money), and change to another card as soon as you stop.
