iphone se sim not supported
Hello,
My girlfriend and I bought an iphone se in the United States a few weeks ago. We live in the Netherlands so we asked for the correct model (A1723) and a sim free phone so it should work on our carriers. We didnt have a nano simcard from our carriers at the time so they unlocked the phone with a sprint card (no contract). Now we're back in the Netherlands and we tried out our new simcard and we get the error "Sim not Supported". It's almost as if the phone is not sim free. We called apple support in the US and we were talking for more than an hour and he couldn't figure out the problem. According to him the phone was unlocked.
We also called our carrier (simyo) daughter company of KPN and they said everything was ok on their end, the problem lies with apple. So we're really stuck here and I don't know what the problem is. Can someone assure me the phone is unlocked because I'm still not convinced. And in that case, what am I supposed to do because the lady who helped us told us it was sim free...
Thanks in advance.
