The chances of me being genuinely amazed at something I see a Belgian tech company achieve are rather slim. But occasionally, it happens. Last week I went to local entrepreneur meetup BetaGroup and saw five startups pitch their stuff to the 200-headed audience. The last one to get its five minutes of fame was Cherry, a new mobile operator that promised to "revolutionize the telecom world". Needless to say, I was as curious as I was skeptical.Then the company's CEO got up on stage, introduced himself, took out his Nokia smartphone, called some random guy in the audience and had him call him back on his phone afterwards. Projecting his mobile phone screen on a bigger screen for everyone to see, he demonstrated how he didn't need to launch an application and just browsed his contact list to call the other person. Standard functionality, sure, but the cool part of it was the fact that the phone was lacking the presence of a SIM card, which is supposed to identify you as a subscriber of a telephony service.
