22nd Adar is a good day, becaue it too is my cousin’s Bas-Mitzwah.
It also is a bad day or maybe not, as this is 7th Yohrzeit of the previous pope, who was there for 26 & 1/2 years.
A text is certainly better than nothing; Just like Nichum Aveilim & Bikur Cholim must be done in person; But assuming this is not an option, certainly texting is better than nothing.
As for your question, if reasonable possibility that you may forget to call her tomorrow, text her right now.
