I wanna earn moons. Sadly, I don't have a phone but only a tablet which isn't supported by vault. Would the following solution work?

Hi. I'm a poor person who lives in the Philippines which is an underdeveloped country. To earn extra money, I join online sites. Recently, I found out that I could earn moons in this forum. Sadly, there's no vault in my reddit app. I found out that it's because I'm using a tablet and the vault is only available in the smartphone app.

I don't have a smartphone because I gave it to my sister whose phone got damaged in 2018. Since then, I only have a tablet which also functions as my phone. It might sound weird for others because I'm using it as a phone. But it's only small so no problem to even bring it outside. It's a 7 inch Samsung Tab A 2016 worth $160 which I've been using for 3 years. Because my priority is paying expenses, I've been stopping myself from buying a new phone for 3 years. After all, it's not really essential because my tablet is still fine.

Right now, I can't afford to buy a phone because there are other things which I need to prioritize first. Also, I don't get paid $150 from my previous earning site so I don't have additional money.

Fortunately, I found a way to use the vault and earn moons. I asked a family member to let me activate the vault and borrow her phone sometimes so I can post here. For example, I made this post on her phone.

By the way, I'm curious. After activating the vault on the device which I borrowed, is it still possible to earn moon if I post contents in my own device without vault support? If this would work, I don't need to borrow phone except during cash out and also I could avoid buying a new phone to save money.

I hope my solution works. What do you think? Would it work? Thanks for reading this post. Also, I appreciate your opinion. Good day and night.
