What does it mean for a website to send me 300 648 prepaid cards?

The 648 prepaid card given by the website is the welfare given by the website. If the website is safe and authoritative, you should be able to use it with confidence. However, if the website is unknown and risky, please consider it carefully and beware of fraud.

The 648 recharge card is generally a game recharge card, not an electronic card. Some merchants will download and give away a certain number of 648 prepaid cards.

Similarly, there are Xianyouge Welfare Mobile Games, Abnormal Mobile Games and Discounted Mobile Games. If you download it online, you will get a 648 recharge card.
