I started to use smart last month and it went well so far. One thing I’ve noticed is that every time I use it at night it’s getting slower from 7 pm onwards. Maybe because many users surf the net at this specific time. The good news is I got a phone where I can use anywhere, everywhere, and any time. It’s so accessible to use especially when I am travelling in Jakarta area. I never tried this outside the city.Wait, I already used it in Serpong and it’s even good. One of these days, I am planning to go anywhere in any places of Java island to test its signal strength.
