Can't tell if HTC One V is GSM or CDMA I recently won an HTC One V and I want to sell it, but I'm not sure what carriers it supports. I won it from an HTC stand I went to, and all they said was that the phone was unlocked so that it could be used with any carrier. How can I tell if it's CDMA or GSM? I can't remove the cover to see an ESN or HEX number, and I don't see any spot for a SIM slot. On the label of the phone it has an IMEI number, an S/N number and a P/N number. Any ideas?

I see listings on ebay that say GSM and other listing that say GSM/HSPA. How do I tell?
Based from an article on Wikipedia regarding to Electronic Serial Number (ESN),


  ESNs are currently mainly used with CDMA phones (and were previously used by AMPS and TDMA phones), compared to International Mobile Equipment Identity (IMEI) numbers used by all GSM phones.


(Emphasis mine)

So, if there is IMEI, then it's GSM. Otherwise, it's CDMA.

  Remove the back cover on the chin. Under the "Made in China" sticker, there should be a small box which should mention something like HTC One V T320e... They are called as Primou U and Primou C for the GSM and CDMA version respectively!
