Can you use Telstra roaming in Vietnam?
Yes, Telstra international roaming works in Vietnam for eligible postpaid customers. Since Vietnam is included in Telstra’s Zone 2 international roaming countries, Telstra users don’t need to purchase a Vietnam SIM card as they can use Telstra roaming in this country.
So, when you land in Vietnam, your phone will connect to one of the local networks, including Viettel, VinaPhone, and MobiFone. Your phone usually automatically selects the network that has the strongest signal where you are.
Telstra $10 postpaid daily roaming pass for Vietnam
Telstra offers its $10 daily roaming pass to postpaid customers travelling to Zone 2, which includes Vietnam. This plan is only available for specific postpaid plans, including Upfront, other postpaid and small business mobile plans.
With a Telstra $10 daily roaming pass, you can access 2 GB of data per day with unlimited calls and SMS. So, if you use Telstra roaming in Vietnam for 7 days, $70 will be added to your monthly bill.
- Eligibility: Available on most Telstra postpaid mobile plans, including Upfront and small business plans.
- Cost: $10 per day
- Includes: Unlimited standard calls and SMS in Vietnam, 2 GB data per day.
Note: If you exceed your daily data allowance, you can purchase an additional 2 GB for $10. However, any unused data expires at the end of each day and doesn’t roll over to the next day. It’s helpful to estimate how much data you need for travel to avoid unexpected charges.
Telstra prepaid roaming in Vietnam
Vietnam isn’t one of the 38 destinations covered by Telstra’s Pre-Paid International Roaming Packs. If you’re a prepaid customer, you’ll need to use Wi-Fi or a local SIM card in Vietnam. You won’t be charged pay-as-you-go roaming rates.
Telstra pay-as-you-go rates for Vietnam (Postpaid users only)
If you are not eligible to use the Telstra daily roaming passes, the standard pay-as-you-go rates will apply, which can get very expensive if you are a heavy data user.
- Data rate: $3 per MB.
- SMS: $0.75 per message.
- Voice rates: $2.00 per minute.
- Warning: At $3 per MB, small activities like navigating Google Maps or using data-heavy apps like Snapchat can cost as high as $300. In this case, purchasing an eSIM can be more cost-effective.
Note: Pay-as-you-go rates apply to postpaid users who are on older $129+ plans, leased, BYO, Premium, or Business Premium plans that can’t use the Day Pass, and to users on other non-Upfront plans who turn the Day Pass off. Prepaid users can’t use Telstra roaming in Vietnam, even at PAYG rates.
