User individual SMS?

Since I'm with the volunteer fire department I always get a text message at the alarm. But if I change the sound of SMS my phone beeps with every SMS I get. Can I somehow change that it only turns off at a certain number alarm.

Info: Huawei P9lite

Yes go to sounds and then change the sound…

If you're just using this phone, download Silence as a music file that you save as the "default ring tone". Then you can make a "special ringtone" for the number of the fire department. Put your phone on loud, then it only rings at the number.
