If this is really the Nexus 5 service manual , then this is good for Android users in Japan: Support for LTE without having to deal with a device that locks you out of mobile network settings : Bands 1, 3, 5, 7, 8, 20.: Bands 1, 2, 4, 5, 8Band 1 is Docomo and Softbank's 2100 MHz, used for both LTE and 3G . As far as I can tell, the Nexus 5 does not support the low frequencies of either carrier, though.CDMA is mentioned in the manual, but as you can see below, it is not listed as a "Supporting Standard". Therefore, my guess is that the reference to CDMA is probably just a standard copy-paste, to be read as "IF this did CDMA, here's what it would be."However, as far as I can tell, CDMA is unsupported. (Also FeliCa, mobile Suica, etc. is not supported.)
