The data plans in most developing countries are actually quite good.
For example, the best overall plan I've used anywhere in the world is in Thailand. You can get unlimited 10Mbit service for $5 a month. The coverage is extremely good even in the mountains or islands, latency is excellent, and I've used over 100 GB without hitting any additional throttles. And that's with AIS. There are cheaper companies and plans if you wanted.
