APN Changer

Note: I am not in the USA and have not personally tested this myself but doing similar works with other carriers I have tested. Please let me know if it works for you or any problems. This May only work with an iPhone 4 or 4S as some people show say its not working are using 3G/3GS

There is a method which can be used to enter MMS Settings in but you will need a SIM Card which the iPhone doesn’t have the settings in for. In the US you will need a T-Mobile Sim (or alike) which seems the easiest to get. This same method can be used on other Carriers/Network as well.

– Make sure you can make calls etc via Go Phone sim
– Install US – GoPhone Profile (When connected via wireless) (or US – AT&T – its the same)
– Make sure Data over the Cell network works (see http://www.unlockit.co.nz/unlockit/?p=568 under “Why doesn’t the GoPhone $50 unlimited plan work”)
– Remove GoPhone SIM
– Place T-Mobile SIM in
– Go to Settings -> General -> Network -> Cellular Data Network (this will come up now)
– Swap AT&T sim back in
– Waiting until it says AT&T up the top again
– Now Enter in the MMS Settings (For GoPhone/AT&T) – If you are using another Carrier please check http://www.unlockit.co.nz/mobilesettings for MMS Settings

I get lots of emails per day and I try and answer them all but the biggest questions I get are below. I will try and answering them.

“Why don’t you include MMS Settings”

– Apple doesn’t include any method of setting MMS Settings at all via any kind of automation thus I cannot set them. I have requested from apple in the past regrading this and maybe in the future I may have the ability to.

“Why doesn’t the GoPhone $50 unlimited plan work”

With the GoPhone “unlimited” plan it does not give you unlimited data on Smart Phones (i.e. iPhones) with the United States AT&T Profile . Saying that for a small percentage of people they do get “unlimited” data on the iPhone without doing anything but for most people you will have to buy a “data feature”  with a limited amount of data.  For some people it doesn’t work at all even after a data feature. Why this works in different ways I don’t know but I presume it depends where in the USA people are and the regional differences between their network.

“You website didn’t carrier unlock my phone”

My website does not carrier unlock iPhones. It sets APN (Carrier Settings) for iPhones.
