SMM country specific possible?

Hi, I'm new to this whole SMM thing and would like to know if there are people with accounts from a specific region, like say China or Singapore? Wanted to do some promotion but understand that it will not work well if say, the business is based in Singapore and the promotors are like everywhere around the world expect in the native country right?

Also lets say i were to create my own so called SMM mini farm (10-20), the best way would be to get physical phones and local sims to create the tiktok, insta, facebook, youtube accounts? And also wondering if any one does accounts for littleredbook aka xiaohongshu?

You can search in SMM panels (https://www.blackhatworld.com/forums/social-media-panels.302/) section as many panels have listed their services there. Any panel might be providing country specific traffic. You can also post in "Want to Buy" if you have customized requirements.

It is possible but integrating with API would require some know-how in this field.
