Will my Iphone still say 3G if it is disconnected?

I have an Iphone 4s and it is updated to IOS 7 and It says I have 3G and I have signal but everytime I send a message it says that the message was not delivered and it won't let me use the internet or anything that requires data such as Facebook, Instagram, Twitter, etc. I tried resetting my network settings but it didn't work. I can still call and stuff, but I'm not sure what else to try. Thanks in advance for any help.

Added (1). I can also receive text messages.

Try calling your carrier about the issue.

  • Why does the Wi-Fi on my iPhone 4 keep getting disconnected? When I'm using my phone the Wi-Fi keeps getting disconnected and goes to 3G then 4 seconds or so later it goes back on. This happens every minute.
  • Why can my iPhone text other iPhones when my phone is disconnected? Today around 10am my iPhone got disconnected (hadn't paid my bill yet), I went to text my aunt (who doesn't have an iPhone) and the messages wouldn't send, 30 minutes later I texted my friend who does have an iPhone and I could successfully send and receive messages. And as of 9hr later, I was able to text another person with an iPhone. What's up with this? Not complaining or anything, just curious why it's happening.
