My Portuguese Lumia 930 came with is a UK Country Variant. I couldn't use google as default search provider. But today I installed a Italian CV and now I can.
Other thing I noticed... With the UK rom I could only limit network speed to 3G or 4G. Now, with the Italian rom, I can set it to 2G, 3G and 4G.
So, my sugestion if for you flash an Italian rom (debranded one, of course) into your lumia 630 and voil?
