Not sure your alarm is going to work? There are a few websites out there that will help you get woken up. If anything try Wakerupper’s Free Wake Up Call, you can use it to have any text message read to your friends.

TelePixie
If you live in the US, Telepixie is offering a free wakeup call service, in return your wakeup call will consist of an ad. The number you use for the service has to be yours, since their is a verification process. (You can’t make your neighbor get woken up at 2 am). Based on the Telepixie website the service seems relatively new and questionable as to it’s reliability.

Wakerupper
Schedule a free call at anytime you want for free. Probably the funniest because you can write it any message you want to get woken up to. I use the service to play weird messages to my friends.

Snoozester
This one isn’t free, but they give you ten free test credits. They have a special SecureAwake feature. This means thatSnoozester will attempt to call you every 3 minutes for 20 minutes until you answer the call and indicate that you are awake.

IPing
Another wakeup service that charges you to get woken up, but they offer a free trial to test the service out. A month of getting woken up every morning would cost you $5.
