Learned that if you call up Globe's hotline, you'd find out if you're entitled to rebates or not. Surprise: I am entitled to a PHP5,000 rebate! I had the option to either apply it to buy a new phone or get the amount via G-cash. I chose to get the G-cash.
Buying prepaid dial-up cards is less expensive. The thing is, although I buy prepaid cards, Jon doesn't. So, the phone bill is still high because the dial-up connection is charged per minute. I've decided getting the PLDT Plan 440 is a cheaper alternative: it's still a dial-up connection, with unlimited number of minutes a month, but each connection can only be 4 hours long ... the link is cut off automatically and you'd have to redial again.
