HP Recommended

I am experiencing an issue with the SIM module on my HP EliteBook 840 G4 laptop. The cellular module (lt4120 Snapdragon X5 LTE) stops working as soon as I insert a SIM card from the Israeli mobile provider Pelephone.

Here are the system details:

  • Laptop model: HP EliteBook 840 G4

  • SIM module: lt4120 Snapdragon X5 LTE

  • Operating System: Windows 10 Pro 64-bit

  • Driver Version: 10.0.19041.4842

The SIM card is recognized briefly and then the modem becomes non-functional. This issue only occurs with SIM cards from Pelephone; other providers do not seem to cause the same problem.

I would appreciate your assistance in resolving this issue or providing guidance on compatibility or firmware updates.

Thank you in advance for your support.

Best regards,

ran.karasenti
