It may have happened to you when you travel abroad, or when you have changed operators, you cannot connect to the web or can not send MMS. If that is the case, it is probably because of the APN seted up on your Vivo V21. So we made the decision to write this content to resolve this issue. We will initially find out what a APN is. We will see in a second time how to configure an APN on your Vivo V21. Finally, we will see in what situations it is necessary to change the APN on the Vivo V21.
What is an APN
The APN means Access Point Name. The APN therefore represents a set of connection data. This connection data allows your Vivo V21 to connect to the internet and receive MMS. An incorrectly configured APN can so prevent your Vivo V21 from receiving MMS or connecting to the internet. You should know that each operator has a different APN of their own.
How you can set up an APN on your Vivo V21
If you want to configure an APN on your Vivo V21, you need to navigate to the Settings menu. Once you are there, go to Network and Internet and Mobile Network . You’ll have to go to Advanced Settings and then finally Access Point Names . Once you are there, you need to select the three dots at the top right of the screen and choose New APN . You’ll then access a form that you need to fill in with the data of your operator. For example, if you are at Vodafone , you must find the Vodafone APN data on the internet and copy it into the form. Most of the time, the APN of each operator are very easily findable. You need to repeat two times the process on your Vivo V21. In truth, you will need an APN for internet and an APN for MMS.
In which case should you configure an APN on your Vivo V21?
In most cases, you may not necessarily need to set up an APN on your Vivo V21 as this is usually done automatically. However, there are a few circumstances that require the configuration of an APN on your Vivo V21.
