That sucks. I would recommend you contact T-Force via Facebook/Twitter to set up the unlock request. If you can use some of the hotspots around you that would also work to chat with T-Mobile. This may take a up to a few weeks to process, but could also be less.
As long as you satisfy all of the requirements dictated here: SIM Unlock Policy | Unlock Your Mobile Wireless Device | T-Mobile
The sooner you contact T-Force or T-Mobile the sooner you can get squared away. Also, $3.00/minute is INSANE.
Hey, minseon, htghtg is spot on here. We don't want the call cost to stand in between you and your crush! Since it sounds like you used this phone with T-Mobile in the states, as long as your phone's paid off and your previous postpaid account is closed in good standing and met the minimum usage requirements/prepaid account met the minimum refills, you should be good to go to reach out to us on FB or Twitter to get the unlock request filed. You can see the full list of requirements in the link above. With an iPhone, it can take time since Apple unlocks their equipment remotely, and in most cases you'll need to reset via iTunes once approved... hopefully you're already on track with this!
