you can't use RW moto x xt1049 as GSM phone without flashing firmware from other carrier or unlocked version. So if u have unlocked bootloader, you have to flash xt1056 firmware and follow guide for gsm unlock for xt1056 sprint (you can found it on xda easily) and get fully operational gsm phone. Otherwise, If you have factory locked bootloader without possibility to unlock it (check it via motorola official site: google for moto x bootloader official unlock, there are some guide) - u can unlock gsm without outgoing calls/texts only.
