Why won't my Ad-Hoc connection work?

I'm in Greece on vacation, and I brought my laptop and my phone with me. I have a dial up connection for my laptop and used that to create my ad-hoc connection. The dial up connection is actually a USB internet on the go. I use pre paid cards and have a connection with a company here in Greece. I want to connect my iPhone to Wi-Fi and would like to know why it isn't working. Thanks for any help

Have you set up Internet Connection Sharing?

  • Wireless internet connection won't work on any device? My broadband connection works just fine, but the wireless connection won't work. All the devices I;ve tried are two laptops (Vaio) an iPad, and three iPhone 5's. When this happens, I usually just turn the router of and on again, but that won't work. I've connected my laptop to broadband to ask this question, by the way. It's on and all the devices can see it, but when I try to join, they say unable to connect. I don't have a password
  • Why won't my iPhone earbuds work on my iPhone but work fine on a computer? So I have the worst luck with earbuds and it happens to be reoccurring. I have a normal iPhone 5 and I enjoy music but when I listen to my songs only one earbud will work while the other one is dead. I can go on my computer and they will both work so I was wondering why they both won't work on my phone?
  • Why does my connection barely work at school? At school me and my friends barely have connection on our iPhones. We usually have to use the wi-fi because our phones won't work. I don't mind using wi-fi because we found out the teacher wi-fi password but I want to know why my iPhone connection never works. P.S. We all use Sprint just in case that had something to do with it.
