Clash of Clans is probably one of the most competitive and popular mobile games in the world today. Supercell, the developer of Clash of Clans, reportedly earned around $1.7B in 2014 due to in-app purchases and advertisements (it definitely defeated Kim Kardashian's mobile game). 

The game is very addicting! I tried it last year but stopped. But I re-built my village and continued just a month ago just in time for Smart's Philippine Clash Tournament. As observed - an average 'clasher' usually spend a Pile of Gems (or 500 gems) a week for upgrades and to speed up things. It's priced at $4.99. 

I usually get my Clash of Clans gems from Google Play Store and I charge it to my personal Smart Postpaid number. It's very easy and worry-free. It's also helpful for people who doesn't have any credit card who wants their gems pronto. Here's how you do it:


Step 1
Go to the 'Shop' section of your Clash of Clan village and select Treasure. Choose among the available pack of gems that you would like to purchase.





Step 2
You will be redirected to the payment page. Click the amount at the upper right corner to know your payment options.

Step 3
After clicking the amount, Google will ask your preferred mode of payment. Click on Payment Methods and Enable Smart Communications Billing.

Step 3
You will be asked to fill-in your number (this is auto-populated with the number of the SIM in your mobile phone), name, and address. Click save after you're done. A confirmation will be sent to you after you fill-in the required information. You can also check and verify this through the Google Wallet site.
