Not really. Many times we wear something called dhoti on top of underwear (instead of pants). This dhoti does not have any pockets. In such cases, it will certainly help. Even when I wear pants over the underwear, having extra pockets is a luxury.

Those are definitely real. All my underwears (trunks) have 2 pockets each and I can put my phone in it. FYI, I’m from India

Did you try puppy linux? It has excellent support for older hardware. I remember that there were some older versions that would even run flawlessly on my 192MB RAM ancient desktop, over a decade ago. Give it a try
