Can Button Wizard send reminder notifications to mobile phones?

You can try: Meow Reminder

After registering with your mobile phone number, you can send reminders to yourself, including WeChat reminders, text message reminders and voice call reminders (the latter two are charged)

I also used email in the past, but I found that after a period of time, it was easily recognized as spam and stopped reminding me. Moreover, the text message reminder of 139 was often garbled, which was very troublesome. Later, I forwarded it and said this, and I thought it was good.
