The reality at the moment is the fact that Pokemon GO is not everywhere.
As interesting as this game is, it is not available in Nigeria and many other countries at the moment.
Delayed global launch due to server overload
According to the publishers, the global launch of game has been delayed due to server overload. The number of players the game gathered in the last few days exceeded what the developers envisaged.
Players in supported countries are currently experiencing glitches, and launch in other regions has been postponed until this is fixed.
The truth is, If you also have a US Play Store account, you should be able to install the game easily. Again, several sites already have the APK file uploaded to their servers, a simple Google search should reveal this.
Although this method is neither safe nor recommended.
