SIM Not Valid
What is happening with a SIM Not Valid error???
I live in Europe. I went to the US and got a T-Mobile 21-Day PrePaid Tourist Plan. I did this a year ago and it worked fine. This time the activation was difficult. I had to call them several times and they did all sorts of stuff to get it to finally work. I returned home today and I put my local SIM card back in the phone. It said it has to be activated and once it started the process it said:
I tried multiple times and got the same results. I went to an office of my mobile provider and they checked my SIM card. They said all was fine, which makes sense since it works in other phones. They tried other SIM cards in my phone and got the same results.
I downloaded and installed the latest version of iOS.
Same result.
I called T-Mobile in the US. I spoke to three different people, all of whom had different stories. One said that they locked my phone and would put in an unlock request, which could take up to 14 days. He said any time a T-Mobile SIM is activated in a phone the phone is automatically locked. This was not true in the past and doesn't seem true now for a pre-paid tourist plan. But as I mentioned, the activation process was not smooth so maybe it somehow happened.
Another person at T-Mobile said they had no idea, but they saw nothing in their system indicating that they locked my phone.
Yet another person at T-Mobile said to do a factory reset. I did this.
Same result.
I tried multiple times to have Apple Support call me back to discuss this, but they never do. They say they will call within 2 minutes, but I get no calls. Instead I get an email that they tried to call and couldn't reach me. I've tried with a US number (my US number is through Skype) and with a number from my country. Neither ever ring. I just get a email that they tried to call, but couldn't reach me.
My phone is useless. I can't activate any SIM cards for reasons no one has been able to explain. I've tried all the fixes that were suggested (other than connecting through iTunes). But nothing has worked.
WHAT CAN I DO?!?!
Thanks!
