Mobile carriers have been the bane of my existence for as long as I've had a phone. First, they take away unlimited data, and then when you try and switch carriers, they hold your phone hostage for a up to a week before unlocking it from their network. There are services out there that can unlock your phone right away for a fee, but why not do the same thing right from your own home? Thanks to the people over at , there is a way to SIM-Unlock any HTC One that is already! Please enable JavaScript to watch this video. Step 1: Find Your IMEI Number To get your unlock code, you are first going to need your International Mobile Station Equipment Identity number, or IMEI. When you input this into the Sieempi website, the service will tailor-make an unlock file for your phone. Either way, just copy that number down somewhere. To check, either place your SD Card into your M8 or attach your USB Drive into a USB OTG cable and make sure you get a notification saying your device is in Host Mode. After that's all settled, copy the Config. You can now attach your USB Drive or SD card to your One. If you are using an M7, you will need to also attach a power cable to the OTG Y-cable—your standard charging cable will do just fine here.

The APN, or access point name, settings are what your One uses to connect to the right cell towers. Each carrier has different settings, but has a pretty extensive list that covers all major U. To change your APN settings, open your Settings app, tap Mobile Data, and select Access Point Names. From there, tap the three-dot menu and select New APN to add your new settings. Alternatively, if you have a M7, you can always to avoid any issues. And that's all there is folks! You should now be the proud owner of a SIM-unlocked GSM HTC One.
