Actually, here's the thing. Smart is strict on they're credit limit. Lumampas ka kahit ng isang piso...redirected ka.

That's why I'm still with Globe.

Works both ways, you can monitor your usage na di lalampas sa budget mo, or maiinis ka dahil di ka makatawag ulit till nabayaran mo na bill mo (Bayad ng advance or wait till bill arrives).

Its one way for the telco to ensure that you pay your bill within your means too. ie, every night, you don't know that your maid uses your phone to make telebabad while you sleep...
pag Globe phone mo = Arrrgh!!! My bill! P10k na pala!
pag Smart phone mo = "my line was redirected to these *$$hol3s(SMART). Then when i called the customer Service, ang daming tanong, inquiry. Nakaka bwisit. Mga 0g*gs talaga. Gagawa gawa ng kung ano ano, may ADA pa, palpak naman."
