How can SIM cards be changed in devices without a SIM card tray?
In preparing for an international trip, I contacted my cell carrier about using my new iPhone 4 with an international SIM and they said, 'no problem, your phone is unlocked for use with an international SIM'. I then called Apple (phone was still under AppleCare) and they took my serial number and said, 'no problem, just open up the SIM card tray on the side of the phone and put in the new SIM.'
Based on their advice, I went ahead and bought an international SIM for my trip, but when I went to insert the SIM, I learned that my phone does not have a SIM card tray. Does this mean my phone doesn't have a SIM card? If it has one, how can I swap it out with my international SIM for my trip?
