Hi Daza, maybe the probkem is yiur phione service provider. Some do not switch on Global roaming to pr =otect yiu if u lu=ose ur phone or it gets stolen. No one can make extremely expensive oversews calls on your phone and kleave yiu with the bill.
Some providers have this as default and yiu have to maje a phonecall to them to request activation of global roaming prior to an OS trip.'
Try calling your provider that yoiu bought the phone with maybe>
