Device Unlock

Dear Sir/ Madam

I’m writing to you about some misunderstandings on my device. Recently, I have purchased IPhone 13 Pro Max from USA with T-mobile SIM card. But, now I am on the trip and I am going to change my SIM card into local one. But, other SIM card  is not working on my device now, I consider that T-mobile has to unlock my phone.
Thanks in advance
