Is personal hotspot free for iphone 4s?

I have all you can eat data for my iphone 4s and have just found personal hotspot. I connected it up to my laptop and was just wondering will I incur any additional charges by doing so?
thanks

By the way i'm on network 3 if that makes any difference.

Well you would need a tethering plan to use the built-in tethering features on your iPhone.

If you jailbreak however, there are apps which allow for it without the carrier finding out (though if they find out, they will switch you to a tethering plan).

Usually, you will have to pay for a Wi-Fi hotspot plan, so what I would do is 1. Jailbreak 2. Install an App called MyWi. It is the best Wi-Fi tethering app, and I would recommend it. They just use your Data plan.

  • Who is connected in my personal hotspot in iphone? I need to know who is connected, because i have 2 connected now while i only connect this to my ipad.
  • What additional cost may occur from making my iphone a personal hotspot? I turned on the personal hotspot option in settings on my iphone but it says additional costs may occur. Does that mean it costs money for me to connect my other devices or just if i exceed the amount of 3g i'm paying for.
  • Using the Personal Hotspot on my iPhone? The Wi-Fi on my Laptop doesn't work, so I can't connect to the internet. I'm using the Personal Hotspot on my iPhone to connect to the internet. My iPhone is connected to my homes Wi-Fi. I'm curious, when my Laptop is connected to the Personal Hotspot, is it accessing my iPhones internet, or is it running off my home internet?
  • Is turning on personal hotspot free? I have a Samsung Galaxy Note II on contract (Orange/EE) and iPhone 5 on pay as you go (Orange/EE). I want to turn personal hotspot on so that i could get internet from Galaxy Note II to iPhone via Wi-Fi. But i want to know if it is free.
