How do i find out if my iPhone 4 is CDMA or GSMcategory: Iphone4
Please view this website: http://support.apple.com/kb/HT4515 to see if your phone is a CDMA or GSM.
The CDMA iPhone 4 has the same features as GSM iPhone 4, the differentiation is the network support. Apple has designed the device to support CDMA EV-DO Rev. A (800, 1900 MHz). This was actually designed to cater to the immediate demand of the Verizon’s 93 million customer base. However, it is not an exclusive tie up with Verizon, the device can be used in other CDMA networks also. !
Sprint is a CDMA signal based network. The only other major US carrier that uses this type of signal is Verizon, but CDMA is very popular in Asia, particularly Japan and South Korea.
Verizon uses CDMA Wireless Networks, AT&T and T-Mobile are the only American Companies to use GSM. Thanks!

If this is for Grandma, let me over-simplify. I may take some criticism with this, but it’s the best I can do… Things like CDMA and GSM (or TDMA, iDEN, AMPS, etc) are just different technologies to enable today’s mobile phones to work.

The easiest way is to look on the right side for the SIM card slot. Slot there – GSM Slot not there – CDMA Plus I think O2 is a GSM carrier either way so they would not sell a CDMA phone.By Rolandinjos February 25th, 2013 at 05:53:56
