I always get text messages from realme wallet and petty cash.

You keep receiving text messages about realme wallet petty cash, and your information is leaked.

This kind of short message is basically an advertisement and needs no attention. Maybe some accounts in your mobile phone are known, or maybe you have applied for or logged on a similar website.

If you don't want to pay attention to SMS, you can blacken the number or set it to not accept such information in the future.
