Actually the process is pretty much simple.
All you have to do is:
and send it to 2 plus the 10 digit number starting 9.
send to 29171234567
(Note: the cell number is fictional so be careful that you might send load to it)
Oh, I just also remembered. I'm using Touch Mobile, lol. Oh well, this one works for both Globe and Touch Mobile subscribers.
Take note also that if you are new in this process, you will receive an automated reply wherein you can add you pin so other people (if they got a hold of your cellphone) can't share-a-load themselves from your load/credit. Do that process in order to put your pin.
