Ive said it before and after spending this week at Spring VON I'll say it again - Voice is boring! - who needs to talk when you can communicate and via SMS and MMS .. gizmo project recently lauched gizmosms - which lets you send free text messages to any mobile phone worldwide..
and even if you feel like you want to talk to this person after you send that text message you are given the option.. I know what you are thinking.. this is freaking awesome.. and it is but the two drawbacks are replies from the people you sent the text message to is not possible so this is only one way.. second voice calls are not unlimmited, as stated on their website = "Call length limited to up to 3 min/call, 10 min/day to most landlines & select mobile phonesaround the world. Additional restrictions apply."
