Hi All,    Quick update. Today I purchased S8 in the stores and as advised I initially used local swiss sim to activate, made few calls, connected to wifi and 4G, LTE. Later I put my Indian sim and it worked.    Thanks everyone for your advice and suggestions. You guys made my wedding day gift for my wife.  Thanks again.  ... View more

Hi, quick update on the same problem.. i went to the shop and before I buy S8 I told the sim problem with the shop guy and told him that if the Indian sim doesnt work then i will return right there.. as expected when I put the indian sim card it says invalid sim. Then i removed and put my swiss sim card and this time it detected and working fine. Then i returned the phone right there and came..   iam reading in many places that if I use swiss sim card and make calls for some time then it will automatically unlock for all region sims. Is that correct? Has anyone done it? I am buying fully unlocked phone and even then samsung has introduced region level sim lock feature. So all I need here, whether the workaround mentioned to overcome the region sim lock is reliable and can be tried? If i go again and buy now and i cannot return the phone again.  ... View more

I am not buying a network provided phone. Here we have electronic shops where I can get fully unlocked phone not linked to any network. Even after that on the box of the ohone itself it was mentioned that european sim only. I need to overcome this issue only. I see some workaround techniques mentioned in internet and the one which you also provided like making some 5 to 10 min call with european sim card. I can do this easily as my wife will be here atleast for next 3 weeks. so she will very well use local swiss sim and make calls. But what after that? after making calls, how the sim region lock will be released on the phone? do i need to enter some unlock codes or some updates need to be done?    Please clarify here.  ...
