Happy new Year 2010 to all of you! And not only to you as in Germany, like in many other places around the world it's custom to send a new year message to friends and family by SMS or give them a call right after midnight. Bitcom estimates that in Germany, 300 million SMS messages are sent over the change of the year. Compared to the average of 80 million messages a day, that's quite a spike, which is, from experience, highly concentrated over the first few hours of the day.
So I wondered how long it takes for messages to be delivered during such an extraordinary traffic peak? Between 10 minutes past midnight and 40 minutes past midnight I sent four messages from a 3G phone to a 2G phone. All messages were immediately accepted my the SMSC. The delivery was then deferred for some time. The first messages was delivered within 10 minutes, the following two in about 25 minutes and the fourth took again a bit longer to be delivered. It look like the fireworks takes precedence. So yes, the SMS Service Centers must have been quite busy 🙂
