spicyayam I just noticed in Gmail that you can send free SMS messages. I haven't tried it yet, but they support these carriers: Indosat Telkomsel Tri Supported mobile operators - Gmail Help
matsaleh But it only give you 50 messages free. I now have 49 remaining and don't know what happens after they're all used.
ronb The info they provide on this is [quote] SMS credit is an allocation of SMS (text messages) that you're able to send to a mobile phone: Initially, you're granted a credit of fifty messages. Every time you send a message, your credit decreases by one. Every time you receive an SMS message in Chat (for example when a phone user replies to one of your messages) your credit increases by five, up to a maximum of 50. If your SMS credit goes down to zero at any point, it will increase back up to one 24 hours later. So, you won't ever be locked out of the system. "Buying" additional messages Keep in mind that if you'd like a higher message credit, you can always send an SMS to your own phone, and then reply to that message multiple times. Every time you send a reply message, your SMS credit is increased by five. Effectively, you're buying more messages by paying your phone company for these outgoing messages.[/quote]
matsaleh Markit wroteJeeez guys an sms costs about 400 rupiah I think - lets not get to excited here lol Only Rp300 on Simpati, but when the other half sends more than 20 or 30 a day (!), it gets expensive. Indonesians love to sms.
