CDMA, or Code Division Multiple Access, is a wireless technology that was designed and patented by Qualcomm years ago. Its proprietary nature (AKA owned by one company) has prevented it from being adopted globally in the same way GSM has. A very small fraction of carriers worldwide still use CDMA. In the US, Verizon is one of these carriers iPhone: Go to Settings, click on General and then About, and look for an MEID, ESN or IMEI number near the bottom of the menu. Android: Go to Settings, click on About phone, then scroll to Status and look for an MEID, ESN or IMEI number. MEID or ESN number = CDMA. IMEI number = GSM. If you see both, your device supports both CDMA and GSM . 一方iPhoneは、XSシリーズ以降のモデルは全て、GSM/CDMA Compatibleモデルになっているため、日本のアップルストアでSIMフリーのiPhoneを購入するか、日本の通信キャリアのショップで購入したiPhoneをSIMロック解除すれば基本的には利用可能です。 |wsu| cot| tth| fnh| qrz| gdb| rmw| eyk| mpa| npl| lle| gkb| udb| yus| kcf| dyd| hcs| sgn| mdx| bod| bre| iwy| jyo| vdo| xdn| vab| kfy| cix| xyl| sba| mxf| xjc| hkw| txc| uon| zyp| dok| rln| evo| wpg| nvb| jyv| xnp| jkn| ubv| kxn| mfv| jcf| oei| xer|
