从你给的链接抄了一段 I had the same problem. Bought a launch day Verizon iPhone 6 from an Apple Store. I put my AT&T SIM card in and I got 4G, but no LTE. After going to an AT&T store and getting several new SIM cards, they told me that although the iPhone 6 supports all the LTE bands for Verizon and AT&T, each carrier uses different parts of each band. I eventually gave up and returned my Verizon model for an AT&T model.
