Is it normal for young students to confirm that there are only phone calls and no text messages?

It is not normal for the baby to confirm that there is only a phone call without a text message. Because the school will inform parents to confirm through various channels, including email, text messages, telephone calls, letters and so on. In general, make sure that the call is the same as the text message. You didn't receive the SMS notification, so I suggest you contact the relevant school staff. Therefore, it is not normal for children to confirm that it is just a phone call without a text message.
