Why should I write automated SMS without diacritics?

A standard SMS has a limit of about 160 characters when written without diacritics.

If you use diacritics, emojis, or special characters, the message may be split into multiple SMS, which can increase the sending cost.

Recommendation:

Write messages short, clear, and without diacritics.

Example:

"Hello! You have an appointment at ABC Clinic on #D, at #H. For changes: 07xx xxx xxx."
