Does divorce take effect if the husband made it conditional in writing via a mobile phone message, and the wife did not understand what was asked of her and therefore did not do it?

If the wife is someone who cares and minds the matter – meaning, if she knew what was required, she would do it – and her husband divorced her based on a conditional divorce linked to an action she would perform, then she performed that action out of forgetfulness, ignorance, or compulsion, the divorce does not take effect. Similarly, if the husband intended to inform her of the matter but she did not become aware of it, the divorce does not take effect.
