Galaxy S9 region lock

  • I’m looking to get a network unlocked S9 in the US that I can use my uk SIM card in. Heard conflicting stories of if this would work so wondered if anyone could provide clarity.


Speaking to Samsung online chat they said it would be region locked to the US and the only way that my uk SIM card would work in it is if I was to put a us SIM card in it initially and make a 5-10 minute call. Apparently this turns off the region lock and would allow me to then use my uk SIM card in it with now issues. 


However, going to many stores in the US they say this isn’t the case and that it is internationally unlocked and that my uk SIM card will work straight away. 


Obviously buying a $10 us SIM card to make a 5-10 minute call is no real inconvenience however I like to have all the facts before making a decision, and this is just confusing.


 One final note, I was told by the guy in Best Buy (US store) that in Europe the phone has two sim slots (I guess for dual sim or for sim/memory card) but the us version only has 1 sim slot. Any idea why this would be?


thanks in advance.

I have a US unlocked Galaxy S9 from T Mobile, and I used it a lot, talked more than 10min etc. I came to Amsterdam, bought a sim card and it gave me "sim region locked" error.  Why do you sell "unlocked" phones that don't work anywhere but one country?

I faced the same issue with my S9 when I moved from UK to US. But soon after arrive I inserted my AT&T SIM card and it's asking for network lock PIN. I also tried 5 minutes call on roaming but don't know why it still shows me the same error. then I found this Samsung S9 Region Lock Solution. they finished the job within a few minutes. now after 4 month still I m using AT&T Sim card on my G960F UK Version.
