Using Google Calendar to send free SMS

I recently wrote a guest post on gHacks and decided to share it with you guys as well. If you set up two Google Calendar accounts, you should be able to send instant messages between any two phones quite easily.
Since the service allows you to register one phone number to send free reminders to, all you need to do is create an account for yourself, register your friend’s/spouse’s/etc’s phone number, and create an account for the other party, registering your own phone number. Remember to set a default reminder for both calendars. It needs to be SMS, and say 10 minutes before.
When you want to write a message, simply create an event, 15 minutes in the future, and type your message in the “What” field. Save the event, and your girlfriend, or whoever you registered should get this message. You can even use it to send timed messages to someone.
The messages will be cut off after 60 characters, but you can create a string of events, 1 minute apart to send long messages. The great thing about this is that your SMS messages are stored automatically, since they are in an event form. You can even create a separate calendar in your account names “SMS”, now you have a record of all messages sent to your wife for example.

Goodness, that sounds like a lot of work! Aren’t there already websites out there that send free SMSes for you?
I’ve enjoyed using Google Calendar’s SMS service for reminding me of appointmnets – partly because it actually reminds me of stuff I’ve forgotten, but also because it’s just such fun telling my friends, oh, that SMS was just Google reminding me of X
Easier, faster, more intuitive: twitter.
Create 2 accounts, link each phone number to an account, activate SMS notifications on each account, and follow each account from the other one. To send an SMS to one of the numbers, just post a message from the other account.
Another great feature of twitter is about groups, using multiple subscriptions. As you can send twitter messages by SMS, it’s a cheap way to stay in touch within a group of friends.
Just remember to make the accounts private, because you don’t want everyone to know you loved the night you just spent with your girlfriend.
Hi Jill!
Actually I don’t really use this, it’s fiddly, and I actually don’t like SMS at all. I would only really send to my girlfriend, but my phone plan is set up so I talk to her for free
I just thought of it as an option 
Geoffroy, to me that seems exavtly the same. I haven’t really found myself liking twitter, although I will look into it more and take a look!
Thanks!
