Samsung Galaxy S6 SMS Delivery Report Issue: 'Card Expired' Error with Maxxim and Blau Networks

Hello.
I have the following problem. Sometimes it happens that when I send an SMS to someone, I have a delivery report "the card has expired". Also, not all text messages reach me. I send a lot of text messages due to my professional activity. The problem is in some network settings, because I transferred the sim card to another, primitive Samsung and also do not receive these SMSs. I have a new operator since yesterday, Maxxim network, before I had Blau and the problem was the same. These are German networks, I live in Germany. The daughter has a Lebara network and SMSs come to those numbers that I do not get. What is the "card expired" message at all? I speak a bit too little German to call the hotline. It is strange that there are two different operators and the problem is the same. Does anyone have any idea what to do here?

Check out another card including samsung. Although it seems to me that it's the operator's fault.

Probably not a card, only the time of delivery is over. The time of delivery should be extended to max.
On the other hand, how much you send and all this under the subscription, that is for free, it can limit a bit.

I have translated the card from my daughter, text messages are coming. For me, this "card has expired" message I have immediately after sending a text message. And I normally pay for text messages.

Since the other card works, there is something wrong with your number. You must report to the operator.
