Can't resolve stupid Issue! 7UC1 Not activated on network.

I don't think any of my texts are going through - aswell as my calls. Everytime I try to make a call it says "7UC1 Your phone is not activated to the network." And it tells to me to call self service. I can't log in to self service or call because I dont the username or password my mom set my phone up with. I can't call 611 because I don't know the pin, and because of this I can't reset it with self service. Im at a dead end and I'm getting very annoyed with koodo. I never use to have these issues with Virgin Mobile when i was with them in the past. Please help. UPDATE. Ive been trying to resolve this ridiculous issue and noticed that someone gave advice to turn on and off airplane mode and I should be able to call again. After doing this I attempted to call someone and it wouldnt even tell me the regular message it not pops up and just shows a text box saying not connected to network and instantly ends the call. It is also doing this with 611 and even if I did have the information like my pin, which i dont, I still wouldnt be able to resolve this issue. Im very unhappy with koodo.
