Hi,
I'm using a decade old modem. Huawei B660 3G modem
Photo of the modem:

Buy a SIM card extender ribbon cable. Make sure you get the correct size e.g. micro to nano, etc.

Thanks for your suggestion though. Though I did thought of - Using old, unused 2G phones with the "Big" sim card, and use it to dial USSD.
My parents still keeping these phones

This is likely to happen, so do it gently.
I tried once , taking out my wife's Oppo A5 - It has only 1 sim tray for 2 MicroSIM cards and microSD.
Gawd, that thing is even more fragile than my Samsung with 2 separate trays.
Tried once and will never try again.
