Update from baseband NCE to OI5 I don't receive OTA updates HELP!

I can't get any updates on my phone, I am aware I am not using ATT carrier actually I live in Mexico and I don't receive OTA updates, is there any way to update to Lollipop 5.1.1 which just released? I am in KitKat 4.4.2... My Baseband is NCE
