Activating Sim transferred from another provider

[hinspeter]

Hi, I put a new sim in our existing mobile (purchased in December) and we can text to and from this device with the new sim, however no calls, and when we try to submit the code texted to us it doesn't go through. So we can't complete activation. We have two other sims to activate but don't want to do them until we can figure why our daughters phone isn't working.

I realised that I needed to have the existing sim in, so I tried it again, and the one time code is not sending. Please help!
