How to change Iphone network?

I'm not on any contracts or paying monthly for anything yet so can I change change the sim card to a different network one? Or what do I need to do?

I honestly think that if You are proffesional do it yourself or just take to the network store you want to switch to. For the best results. I'm not so sure if there's youtube video on that or not but I will check it out

For unlocking you can approach any one of the online unlocking service provider like http://www.mobile-unlocker.com/apple-iphone/rs2wp9/ .Here you can unlock your iPhone using Remote unlocking method. It's one of the best and safe way to unlock your iPhone without jailbreaking.

  • Wi-Fi on iPhone keeps saying unable to join network (my network name)? How can I fix this! It's been like this for a week but it works on my laptop fine. I tried unplugging it for a few seconds, I tried resetting network settings, I tried turning my phone off then on again, and I know I'm typing it right. I even typed it in upper case AND lower case. Does anyone know how I can fix this?

  • Looking for a way to evenly share network speed in a house network? So my problem is that I play games online, that need a good ping. Whenever anyone from any other computer goes to load a video on youtube in a high quality, it takes up all the speed, gives me more than 400 ping and just pretty much cuts everyone else out. Is there a way to share the network evenly between every user? Our download speed is about 6mb/s, so if we have 4 active users, i'd like it to share it like 1.5mb/s each.
