Kopierad från länken (https://forums.oneplus.net/threads/oneplus-2-regional-versions-explained.338780/) på OP forum Here’s a breakdown of the differences (for EU/NA, bands in bold only available on that version): EU/Asia GSM: 850, 900, 1800, 1900MHz WCDMA: Bands 1/2/5/8 FDD-LTE: Bands 1/3/5/7/8/20 TDD-LTE: Bands 38/40/41 3 and 20 are used almost all over Europe, but not at all in North America. Band 8, although available in both versions, is used in Europe and India but is seeing increasing adoption worldwide. North America GSM: 850, 900, 1800, 1900MHz WCDMA: Bands 1/2/4/5/8 FDD-LTE: Bands 1/2/4/5/7/8/12/17 For NA, the removal of bands 3 & 20 allows us to add all the GSM bands you’ll need. China GSM: 850, 900, 1800, 1900MHz WCDMA: 1/2/5/8 TD-SCDMA: 34/39 TDD-LTE: 38/39/40/41 FDD-LTE: 1/3/7 The Chinese version will have very limited 4G compatibility in Europe and North America. More importantly, it only has one IMEI meaning you will not have dual-SIM capability outside of China. If you like having dual SIMs, do not buy the Chinese version.
