On my iphone why is their a circle ar the top?

Right where the 3G sign would be it turns into a white circle. Every since i paid my first bill now my internet connection is slow and sometimes doesn't load

That means that your internet is very slow. There's
1. LTE
2.4G
3.3G
4.Edge
5. The "circle"

These are all the intensities for the internet. Contact your provider because you are not getting for what you are paid for…

The o is GPRS which is 1G. Why it is showing that, I don't know. Should contact your carrier about it.

Just so you know the iPhone can connect (assuming the iPhone 5) to these connections
1G - o
2G - E
3G - 3G/HSPA
4G - LTE
Wi-Fi

  • Why is there a circle where the 3g symbol should be on my Iphone 4s? I just activated an iphone 4s from virgin mobile and ever since I got it, it has had terrible 3g coverage, everything is slow and half the time won't even load and the 3g symbol shows up rarely for like a minute and I'm very frustrated with this because I paid full price for my iphone to have it not work at all in the way I want it to.also, I can text and call fine its the 3g network that is not working.
  • Why is there a circle instead of 3G? I have an iPhone 4 from cricket my phone is being really slow and all you see is 4 bars of signal company name and then that circle in place of the 3G signal why is it there and how do I get rid if it?
  • Why is there a circle in the top left-hand corner of my iPhone's screen? Today, I turned my phone off and back on again and when it turned back on, there was a circle in the top left-hand corner of the screen. When I click it, it comes up with the options "Voice Control," "Favorites," "Device," and "Home." What is this? Is is some kind of new update? Is there a way to get rid of it?
  • Why do poor people care more about their image and buying nice clothes than feeding their family or paying bills? I see tons of poor people who make less than 20k a year spending their entire income on nice clothes and shoes and purses and makeup. Their children are starving they can't even afford to use the air conditioner or pay for electricity but they absolutely need to buy a new iPhone or a new pair of high heels
