Reading SMS mobile text messages received by mobile number for SIM in slot in computer itself running ZorinOS (not via paired mobile)

Hardware Support
1

I would like to be able to receive and read messages sent to the mobile number associated with the SIM card that's in the hardware sim slot in my computer itself that is running Zorin OS.

This is not a question about reading and writing messages sent/received via a paired or attached mobile to my Zorin OS machine. So this is not a question about Zorin Connect nor about KDE Connect.

My computer is a Panasonic FZ-G1 Mark III Toughpad tablet PC, with an i5 x86-64 CPU and 4Gb RAM. I have it setup to offer booting into Zorin OS or Windows 10 via GRUB. In Windows 10, I can read the messages sent to the SIM as standard Windows system notifications. With Windows 10 EOL next year I'd like to make the machine fully Zorin in terms of disk partition, eventually, without the option for Windows. Perhaps I'll keep the Windows setup and run it as a VM though.

Why do I need to read messages sent to the mobile number of the SIM within my Zorin OS computer? Answer: 2FA logins for the mobile operator that provides the mobile data for the SIM. When I want to login to check the account for the SIM, e.g. top up more data or other adjustments, logging in sends a SMS text message to the number of the SIM, so I need to be able to read it.

But as a work around, fortunately my current operator, giffgaff in UK offers to either send a SMS to the number or to the email associated account - which I have now set as default. So with email access straightforward I don't have this problem of being able to read the SMS at the moment. But I'd like to future-proof by exploring the read SMS text message on a SIM installed into the machine running Zorin OS. In case giffgaff change their 2FA/MFA policy. But I also note that other operators such as Vodafone only seem offer SMS. Not only is my question about future proofing but it could also help others. I've noticed some regular laptops also have SIM slots such as from Dell.

I'm looking for a solution from someone else who has actually succeeded first of all. Everyone can use Google, including myself.

Here's what I've looked at but not yet tried (I'm not encouraged to yet owning to what I've read about them so far):

Access SMS from Notebook SIM

Accessing SMS from SIM card attached to notebook SIM slot on Ubuntu 22.04

Based on the provided search results, here’s a step-by-step guide to help you access SMS from your SIM card attached to your notebook’s SIM slot on Ubuntu 22.04:

  1. Ensure your notebook’s SIM slot is recognized: Check if your notebook’s SIM slot is recognized by Ubuntu. You can do this by running lspci and looking for the WWAN (Wireless Wide Area Network) controller. If it’s recognized, proceed to the next step.
  2. Install Modem Manager GUI: Modem Manager GUI is a software that provides a graphical interface for managing your mobile broadband connection, including SMS functionality. Install it using the following command: sudo apt install modem-manager-gui
  3. Configure Modem Manager GUI: Launch Modem Manager GUI and follow the on-screen instructions to configure your mobile broadband connection. This may involve selecting your SIM card, APN (Access Point Name), and other settings.
  4. Verify SMS functionality: Once configured, Modem Manager GUI should allow you to send and receive SMS messages. You can test this by sending an SMS from another device and checking if it’s received on your notebook.
  5. Optional: Configure USSD (Unstructured Supplementary Service Data) functionality: If you need to use USSD-based services (e.g., sending SMS using a specific code), you may need to configure Modem Manager GUI accordingly.

Additional Tips:

  • Make sure your SIM card supports SMS and voice services. Some SIM cards might be data-only, which would prevent SMS functionality.
  • If you encounter issues with Modem Manager GUI, try restarting the service using sudo service modem-manager restart.
  • For command-line access to SMS functionality, you can use ofono (a Linux-based SMS and USSD client) or smsd (a simple SMS daemon). However, these options may require more technical expertise and configuration.

Important Note: The success of SMS functionality depends on your SIM card’s capabilities and the mobile network’s configuration. If you’re unable to access SMS, it may be due to limitations imposed by your service provider or the SIM card itself.

By following these steps and tips, you should be able to access SMS from your SIM card attached to your notebook’s SIM slot on Ubuntu 22.04.
