Have you considered going to the Maldives and staying on a local island?
Their 4G coverage is now VERY good, while staying on a local island guarantees ocean proximity and is affordable. Rooms start from ~$30 per night (but this is the most basic one on a random island). The food in cafes is priced pretty much like in Eastern Europe.
It is illegal to enter as a tourist and work as a DN in any country.
Had you worded your question like: "Will I be OK if I say I'm a tourist and actually work as a DN?", the answer would've been: "No worries, everyone does that, you'll be fine".
