lol, yes maybe its overloaded, but most of the time it works great, like i said my stepson is sat at my pc must be 6 hours a day just sending his gf txt msgs, but she doesnt reply thru her phone to chikka, as hes got a smart sim in his phone, so it only cost her 2php to text him, but iam sure chikka only charge about that..
try it a few times thru the day, not just once, maybe busy when the pinoy's are up and about, but i never really had problems with it. thats all i used to chat to my wife for 6 yrs , ICQ and chikka.
