MySMS Premium is the upgraded version of the standard MySMS app. It offers additional features such as ad-free experience, advanced customization options, and unlimited backup of messages. With MySMS Premium, users can also schedule messages, set reminders, and use custom themes. The premium version also provides users with more control over their messages, including the ability to recall sent messages and set expiration dates for messages.

If you truly need mysms-like functionality, here are legitimate options – some even free.

If you bought mysms before the subscription model changed, you might have lifetime premium. Check your Google Play purchase history.
