After the official Pokémon GO release in Japan, many guys are reporting that the game doesn't show up Pokemon, poke stops, or gyms. This is how it was for countries that didn't officially have the game released yet (Malaysia, Singapore, Japan etc) so Niantic may have noticed Sri Lanka along the way, and blocked us too.
Unless it was all Team Rocket. In which case, damn you Team Rocket!
Pokemon Go Banned in Sri Lanka?
Here’s a very sad news for the Pokemon Go players in Sri Lanka! It looks like Pokemon Go is banned in Sri Lanka. The thing is Pokemon Go was never launched in Sri Lanka.
As of now, you can open Pokemon Go alright but you will be disappointed to find that there are no Pokemons nearby. All the Pokestops and Gyms are now gone!
