Greetings sunboy926! I wish I was in France. The good news is that since your phone takes an unlock code instead of using an unlock app, it doesn't require network connectivity to complete an unlock. You'll still need to meet the eligibility requirements to unlock the device outlined here: Unlock your mobile wireless device. Once you've had the opportunity to review that information, you'll want to Contact Us to request the unlock code. I know being overseas might make reaching out a little complicated - but if you still have your T-Mobile SIM card, you can call us free of charge by dialing the plus sign + followed by 1-505-998-3793, or you can reach out to our T-Force team via social media (FB or Twitter) and place the request that way. Hope you're having a wonderful trip!
