I'd be careful with this. I've done that in the past in Malaysia, going through the border from Malaysia to Thailand every 3 months.. Eventually when I took a plan from the airport to travel somewhere else, I got questioned by immigration because of the patterns of staying 3 months and then leaving for a few days. They asked me how I could finance my stays and told me that any work I was doing while in Malaysia remotely violated my visa.

In the end, nothing happened but ymmv. I also know a few people who did the same in HK and eventually got into trouble because of that.

I do think it works well but it's not a long term plan and if you do it, you must plan with potentially being denied entry eventually.
