My mobile phone is set to send short messages regularly, and then I pull out the sim card, will it be sent out?

it can be sent, but it can only be sent through the internet, but this requires that you have customized the service of sending short messages on a website that provides short message service, and it can only be done if there is a balance, and you must have related applications on your mobile phone. To put it bluntly, it is impossible to send short messages without using telecom service providers, and it is possible to send them without spending money, but it is impossible to send more.
