Blyk, a new mobile network for 16 - 24s that's funded by advertising launched Monday. Blyk links young people with advertising  and gives them free texts and minutes every month.  It offers subscribers 217 free texts and 42 free minutes in exchange for accepting MMS (picture messaging) and SMS (text) advertising after that it's 0.15 (BP) a minute.

In order to join users have to be 16-24 years old, live in mainland Britain, own a phone with MMS and be invited. After registering the teen gets a new SIM for his/her phone.  Blyk expects to launch in other parts of Europe in the future.

Comment from Mobile & Wireless News:

Knowing teens, those free minutes should run out in about 42 minutes after receiving the SIM.
