Block sms reception when too many at once

[GBInformatics]

Good evening, I use gammu with raspisms, more precisely python3-gammu. All under raspberry pi os bullseye 32 Bits legacy lite.

I've noticed that when I send more than 4 messages in less than 10 seconds, gammu blocks the reception by putting them on hold in the inbox. I have to empty it to receive the messages again. On the other hand, the programme is still perfectly functional.

Do you have a fix for this ?
