need help badly
hi i bought an iPhone 6s plus 64gb from Australia and my location is Mauritius. My problem is when i insert my sim card it indicates (No Service) and when i go to setting-general-about, the things that i see is as follows
Network Not available
Carrier Orange Mauritius
And when i go to setting- carrier (Network Selection) and turn off Automatic it says that (unable to load network list).
When i bought the iphone it says that it is factory unlock.
Can anybody help me with this problem, i badly need help.
