Hey guys, just bought my new smartphone without data whatsoever, recently I realize I can't live without data, all the games need connection and school WiFi blocks it.

Im quite cluelesson how sufficient 1gb is, I have been using dig prepaid all my life, and recently I had a flier about some hotlink prepaid internet, 1gb rm30 is that good? And will I be able to transfer my sigi number to it?
