Ja it was already activated,but still no signal at all..

the phone does not recognize the SIM, does not ask for the PIN and shows “no SIM inserted”, i tried also to check the SIM in a different phone but still doesn't recognize the Sim.

Hello @Chachi ,

if the SIM isn’t being recognized at all by multiple phones than it probably is defect and you’ll need a replacement. The fastest way to get one would be if you have an o2 Shop near you that you can go to directly receive a new SIM Card. Outside of that, you’d be best of contacting the hotline or chat, so that they can send you a replacement.

Kind regards, Sven
