What Is an APN?

AN APN stands for Access Point Name.

An APN is basically settings required for your connection between the mobile network and global internet. It is a common gateway used in modern GSM, GPRS, 2G, 3G, 4G CSMA/CDs. So basically to access DATA connection on your mobile device you need to have an APN number. Your service provider carrier will check if your device can be given a network connection at an instance. It also determines what kind of network will be used and other security methods. So, this is how APN helps you to connect to wireless services.

When you ask for wireless data connection, your request is directed to your Carrier provider. It checks your APN settings and generates a new IP address and makes your separate gateway connection. Now if you don’t know IP (Internet Protocol) is a 32-bit unique identification number used to specify your device exclusively among billions of other devices on the Internet. An IP address determines your identity on the internet. We may include a detailed discussion about IP in some other article. But here let’s continue about APN.

What Is No Apn Error:

Now once we have seen what exactly APN is, let’s move forward to what is that irritating “NO APN SPECIFIED” error means. So, as we can judge right from appearance it suggests that your device couldn’t specify the correct APN settings. So, how actually did the happen? Is it the result of some random clicks by a dumb kid or there are some conflicts in your mobile device or carrier services? Well, you don’t really need to bother too much.

As APN settings fall in some complex category of WIRELESS NETWORKING. Hence we think understanding that is not everyone’s cup of tea. But we will make sure that you get it easily. So, let’s first understand different APN settings:

APN: This field contains the name of your APN, typically ‘BSNLNET’, ’BSNL’, ‘AIRTEL’, ’JIO’, etc.

APN TYPE: This field has different options like Generic, MMS, wap, supl.

MMSC: MMSC (Multimedia Messaging Service) is specified for MMS services.

PROXY: This option is provided by some providers to set up proxy connections.

Typically all these options are auto-configured. So, when you insert your SIM card and activate it these options will be automatically selected. But sometimes you can change those as per your needs. Particularly, when you are on a trip where ROAMING CHARGES may apply. In our case when you see “NO APN SPECIFIED” error.

How to Fix No APN Specified Error:

So, finally, we have preceded the last step. If you ever got such an error you should try the solutions listed below. If that doesn’t work then you should contact your carrier provider immediately. As some carriers don’t permit their users to modify the APNs manually.

Editing existing APN:

  • Switch off your device and remove the SIM card. Now insert it back again and switch your device on. Doing this you will set your carrier settings to default.

  • Now go to settings and update your current APN settings to those you noted from the Internet.
  • Reboot your device and check for the data connection.

If none of these works, try switching your device to factory reset mode.

Please note that doing a factory reset will erase all your saved data and information and hard boot your device. So, you need to backup all your important data as it might be lost.

iPhone Or iPad fix:

You can find your APN and modify it at:

Go to Settings Cellular Cellular data options Cellular Networks
