If you’ve recently purchased a new SIM card, you may be feeling a bit overwhelmed and unsure where to start. So, how do you properly activate a 4G SIM card and get it up and running? Let’s take a closer look at the activation process for Vinaphone and MobiFone 4G SIM cards in this article.

It’s important to distinguish between registering for a 4G data plan and activating a 4G SIM card. These are two completely separate concepts! This article will guide you through the process of activating your 4G SIM card, which means enabling 4G services on your SIM, not signing up for a 4G data package.

First, you need to check if your SIM card is a 4G or regular SIM. Open the Phone app and enter the code *091*38#OK.

If your SIM card is a regular one, you’ll need to purchase a new Vinaphone 4G SIM card. Then, on your phone with the old SIM, enter the following code: *091*38*20*serial number of the 4G SIM#OK.
