What is an APN ?

March 22nd, 2014 No comments

So what is an APN? APN stands for Access Point Name. It is an identifier for access to data on a mobile network. It is a name usually something like “internet” with an optional username and password.

If you have the incorrect APN for a mobile network then you will not be able to access any internet from your device.  Every mobile network has different APN Settings and may be different even on different plans on the same mobile carrier.

Now this explains the problem. As there are over 1000 mobile companies  around the world including MVNO (Virtual Carriers) each of those carriers has different APN Settings needed to access internet from the Android, iPhone or whatever other phone a person has.

Devices like the iPhone only have a limited number of these carriers built in (usually the carriers which have an official relationship with Apple) but this may only for a small percentage of the total carriers around the world . Similar with Android and other phones, they don’t have the settings built into them for all the carriers.

How do you find what the correct APN is for your carrier? And how do you actually put the settings into your phone? This can be the hard part sometimes.  You can ask your carrier but sometimes due to various issues such as language barriers and even down to the people who answer the phones/answer emails don’t know (as I’ve found) . Getting the settings into the phone so you can use them is the next sometimes confusing part for people too.

There are a large number of websites which have APN settings on them but they are usually not updated a lot (or not at all) , largely wrong, so this website was set up to list all these APN and make it easy for iPhones (and others)  to get them into their devices. It is usually updated every week with new settings, changes and fixes.

If you have an iPhone and data is not working go to:

http://www.unlockit.co.nz

on your iPhone and search for your Country/Carrier.For other phones go to:

http://www.unlockit.co.nz/mobilesettings

on your computer and do the same and it will list the settings as well for you to enter. If your carrier is not listed please let me know and I can investigate the correct settings and get them added in.

Hotspot APN Settings not Saving for Users.

March 20th, 2014 3 comments

Quite a few people have contacted me and there are others on other sites (including Apple’s discussion forums) have been complaining that APN Settings for Hotspots don’t save when changed. (Thats if you can edit them in the first place)

This is not across all carriers/countries/users as far as I know (It works for me for example) so it may be determied by what carrier you are using or other factors

I am sure Apple will resolve this “issue” maybe in the next update but at the moment there is really nothing people can do.

I just wished that Apple allowed people to set this Hotspot setting (and MMS as well) in profiles like I do with Data APN Settings.

Update: It seems this issue is affecting people who are using Carriers which don’t have builtin settings within the iPhone (Thus using the generic/default carrier settings). (Or I may be wrong)

Config setting security display issues on iOS 7.1

March 18th, 2014 1 comment

iOS 7.1 has introduced a number of changes but one of them is the way config settings are displayed to users before they are installed.

The first image below is one from Pre iOS 7.1 and the second one is from iOS 7.1.

The first issue you will notice that if you include settings rather than APN Settings they are not listed on the page and just has … instead. I include a Web Clip (Link to my website) which gets installed and this is not shown in iOS 7.1 here. If you click on More Details you’ll see it but most people won’t do that.

This means that someone else could install other settings on your iPhone such as proxy settings to force all your data thru a third party server. 99.99% of users wouldn’t notice that other options are included on the config files and this could be seen as a security issue.

The second problem is under the Signed part. It now shows the Base signing certificate not the main signing certificate name which isn’t that bad just not showing correctly who has signed the configuration file. Signing Certificates are easy for anyone to get but if you see that someone else has signed the file rather than the website you are going to, you could question it.

The third issue, well not really a security issue at all, is in iOS 7.1 things are quite squashed up and the Install button is very close to the rest of the other wording making it look not so nice.

iOS 7.1 and RSims

March 17th, 2014 No comments

I have had a large of emails with people upgrading their iPhones to 7.1 Recently who are using RSims (and other “sim impostors” such as Gevey/XSim etc) as their iPhones are carrier locked because these devices are no longer working with iOS 7.1

For people who are using these devices I suggest people contact the company/contact that the got them from and ask if they will actually work with 7.1 before you update to the newer version or you will have an iPhone which won’t be able to make calls/data.

I suggest people actually get their iPhones carrier unlocked properly via the original carrier of the iPhone (Or buy a factory carrier unlocked iPhone) and don’t use a unsupported piece of hardware to get around this.
