WARNING... If you intend to use your Sun Sim to call the customer hotline of Globe by dialing 02.7301000, please note that your call may most likely last for more than 6 minutes and may be more expensive than just getting a Globe prepaid sim (Php 40.00) and calling the hotline free from that sim.
This should be voted as the best question of the year!!!
Seriously, send a tweet to @talk2Globe or visit a Globe Store. Forget calling the Globe Hotline from your not so smartphone.
