Why does my iPhone not say 1x OR 3G?

Why does my iPhone not say 1x OR 3G?

Added (1). I have an iPhone 4 with my carrier being Verizon.
My phone does not say 1x or 3G & it will not call anybody when not on Wi-Fi.
I tried during Cellular data on & off but it's not working.

Sounds like you might have a bad SIM card. Have you taken it into Verizon yet? They would be able to tell you for sure.

I'd take it into Verizon & have them see about it. IPhones wouldn't say 1x.

It'll be
GPRS for 1x - 1G
EDGE for 2G
3G for 3G/HSPA
4G for HSPA (on select carriers)
LTE for LTE
