Forgive my ignorance but this is the first time I've ever traveled abroad and I am getting conflicting information about unlocking my phone. I have a 5s that is still under contract with AT&T. I will be in the UK for a few weeks and I wanted to buy a month-long prepaid SIM card from a provider there so that I could have unlimited internet. This works out much cheaper than AT&T's astronomical rates for international travel. I called AT&T and was told they cannot unlock the phone because it's not paid in full. Great. I guess my question is, is there a legitimate way to unlock my device so that I can use it while I travel, or am I stuck using AT&T's international data plan? I've called a few friends to see if anyone has an old, off-contract iPhone that I could borrow but they're in the same boat I am -- we all sell our phones when we upgrade, thus no one has an old phone lying around. Thanks.
