- Access Point Name (APN) stands for Access Point Name.
- It is the gateway between the mobile network and the Internet.
- Whenever a smartphone or mobile device uses mobile data, the mobile network operator (MNO) reads the APN to assign an IP address to the device and determines the access method and how the device will access the network.
- In other words, the SIM card is a pass, and the APN is the gateway. The pass must be paired with the correct gateway to be effective and connected to the network.
- When you insert a SIM card, the Access Point name settings are usually configured automatically with the carrier because the APN is already built-in from the smartphones sold locally by the local mobile network operators.
- If the default settings don’t work, you should set up the APN manually.
- Some of our Ola Tech phones are from Japan. If you use a SIM card from another country, you may have to set the APN manually.
- This means that your mobile does not have an APN configured.
- Reset your Android Network Settings may repopulate your network automatically 👉 To do this, reset the network settings on your Android.
- APN names are not case-sensitive.
- From ETSI TS 123 003 V16.3.0 (2020-20) – the most recent version of the technical specification paragraph below shows that the case of alphabetic characters is insignificant.
The encoding of the W-APN shall follow the Name Syntax defined in IETF RFC 2181 [18], IETF RFC 1035 [19] and IETF RFC 1123 [20]. The W-APN consists of one or more labels. Each label is coded as a one octet length field followed by that number of octets coded as 8 bit ASCII characters. Following IETF RFC 1035 [19] the labels shall consist only of the alphabetic characters (A-Z and a-z), digits (0-9) and the hyphen (-). Following IETF RFC 1123 [20], the label shall begin and end with either an alphabetic character or a digit. The case of alphabetic characters is not significant. The W-APN is not terminated by a length byte of zero.
