Unlock for international travel vs unlock for domestic?
I am traveling in Japan using my prepaid handset and I tried to unlock my phone and insert a SIM card from a Japanese carrier. The unlock said it was successful but when I put the Japanese SIM in it did not work. I took it to the manager and he showed me it worked on other phones and said it was a problem with my phone specifically. He claims that sometimes when you unlock a phone the carrier only unlocks it for domestic use and I might need to request a specific international use phone unlocking. Is this true, and if so how do I do it?
