New in iPhone 5 is the support of DC-HSDPA and LTE. LTE is the new hotness as it is 4G technology and touts a maximum speed of up to 100Mbps. However due to the various frequency bands deployed by carriers worldwide for LTE, and probably due to the limit of current LTE chipset, Apple is offering three models of iPhone 5 (other than those by memory size) to suit the world wide market.

  • GSM model A1428: UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE (Bands 4 and 17)
  • CDMA model A1429: CDMA EV-DO Rev. A and Rev. B (800, 1900, 2100 MHz); UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE (Bands 1, 3, 5, 13, 25)
  • GSM model A1429: UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz); LTE (Bands 1, 3, 5)

There are two GSM models supporting LTE bands 4,17 and LTE bands 1,3,5. A third CDMA model supports LTE bands 1,3,5,13,25. Not all three models are available in all markets and it depending on your country and carrier.

If you intend to use LTE in home country and while roaming oversea, it pays to choose your iPhone 5 model correctly. For example majority of carriers in Asia are deploying LTE bands 1,3,5, thus you will not be able to use LTE if you have GSM model A1428 (GSM model with LTE bands 4,7).

Apple has published a LTE guide to shows carriers by country supporting the iPhone 5 LTE.
