Besides paying for an unlock code by an independent company? have an Alcatel One Touch Fierce XL & I moved to Europe 4 months ago without unlocking it with metropcs. I managed to use it with 2 different monthly prepaid phone carriers and it was working ok until i decided to go full contract with Vodafone Spain. I would always get the error e505 invalid sim card wifi calling error or something like that, but still, was able to make phone calls and internationally with my home wifi for free. The problem now, is that when I bought a Vodafone new mobile line as it was added to my family's mobile plan, and after inserting my new sim, i choose the option of having to choose one of the optional carriers for phone billing, which i normally skip this option after doing a brand new reset on my phone, so as soon as I did that, my sim card and phone got locked and now i cannot insert any sim card at all even new as it is completely locked and gives me a message to get in contact with my current carrier to resolve this or metropcs. I have tried everything from even Rooting my metropcs and disabling default bloatware apps metropcs always installs. So I was wondering, is it possible to be able to tweak my phones system to unlock it ? Thank you so much.
