Sounds normal to me, SIM cards contain config data for connecting to the network, setting up APN's, passwords etc. Makes sense for the povider to send you to their website to create an account etc.
They installed Facebook too.
The sim is with a sub company of vodafone and the sim was in the phone for a few months before it did this.
What do you mean control? As far as I've known, before the sim/network provider controls your phone to be restarted, you have to click the permission for it to be restarted. But if you said that they have installed facebook, then I guess it wasn't the provider who really made that thing happen, you might have accidentally clicked a link and directed you to a virus since android is really prone of viruses.
You should go ahead and ask their customer service representatives why is that they have installed facebook on your phone. That is your concern right and you have to stand for it!
There's a 3 hour hold with Vodafone. I could try calling at 4am tomorrow although there will probably be the same wait regardless.
