How to activate Viettel SIM card prepaid?

Activating and Managing Your Viettel Prepaid SIM Card

Viettel, a major telecommunications provider in Vietnam, offers convenient prepaid services. Activating and managing your Viettel prepaid SIM card is straightforward, requiring only a few simple text messages.

Activating Your SIM Card

The first step to using your Viettel prepaid SIM card is activation. This is accomplished by sending the activation code, which you should have received with your SIM card, to the number 191. This action will immediately enable your SIM card for use. Failure to activate the SIM card will prevent you from making calls or using data services. It’s crucial to utilize the exact activation code provided.

Stopping Automatic Renewals (Important!)

Many prepaid plans offer automatic renewal options. To avoid unwanted charges, and ensure you’re in control of your spending, you can halt these automatic renewals. Simply send a text message to 191 containing “HUY CODE” followed immediately by “Y.” This will prevent your current plan from automatically renewing and you will have to manually top up your credit as necessary.

Checking Your Data Balance

Managing your prepaid balance is essential. To check your current data allowance, simply send the message “KTTK” to 191. This will instantly provide you with the remaining balance in your account. This is vital for understanding how much data or credit you have remaining and making informed decisions regarding further usage.

Key Takeaways for Viettel Prepaid SIM Card Management:

• Activation: Send the activation code to 191.
• Prevent Auto-Renewal: Text “HUY CODE Y” to 191.
• Check Balance: Send “KTTK” to 191.

By following these simple steps, you can effectively manage your Viettel prepaid SIM card, ensuring you stay within budget and avoid any unexpected charges. Remember to always use the correct codes and commands.
