Hi @Seulcusinier, I'm sorry to hear this.

Have you noticed if it is one specific SIM card that doesn't get a network connection, or if it is a specific SIM slot on the device? In other words, if you switch the SIM cards places will the same SIM still be without a network connection? This would help us find what the cause might be.
