Some phones allow you to connect to both CDMA and GSM networks. This means that you can have signal pretty much wherever you go. However, hacking phones to use such capabilities can take a little time. Now, Motorola Photon Q 4G LTE users have a SIM card mod to help unlock their phones.
XDA Senior Member CornholioGSM released a step-by-step hardware tutorial to help users connect whatever SIM card they want to their Photon Q. Be warned: It is a complicated process, and can potentially mess up your device. As per the norm, you’re responsible for breakage. Here’s a list of the tools you’ll need:
Soldering Station, Hot Air Rework Station with Nozzle Straight approx Ø7mm Dia, Solder Flux (not important), Tweezer, Small wires (you can use bonding wire from old headphones), Screwdriver and Good Nerves
The mod revolves around taking the device apart to get to the SIM already in the phone. Then, you modify it to use other SIM cards. CornholioGSM has not only provided pictures of the mod, but videos as well, including a final test video to show it works. This can be great for Photon Q users who want to play with their phones on other networks.
