Telstra international roaming in Japan: Plans and pricing
There are three different types of roaming options available for Telstra users in Japan: buying an international day pass for postpaid plans, getting a prepaid roaming pack for prepaid plans, or using pay-as-you-go roaming rates.
- International day pass: Japan falls into Telstra’s international roaming zone 2. This means that the day pass costs AUD$10/day, which gets you 2 GB of data as well as unlimited calls and unlimited texts. If you run out of your data allowance, you can buy an extra 2 GB for $10.
- Prepaid roaming pack: Telstra’s prepaid international roaming packs are available in 38 destinations, including Japan, with three options for you to choose from:
- $10 for 400 MB, 15 SMS, and 15 minutes of calls for 3 days.
- $15 for 2 GB, 25 SMS, and 25 minutes of calls for 7 days.
- $25 for 4 GB, 50 SMS, and 50 minutes of calls for 14 days.
- Pay-as-you-go roaming: If you don’t get a roaming pack but still use your phone abroad, you’ll automatically be charged pay-as-you-go roaming rates. These rates vary from country to country. For Japan, you’ll be charged $3 per MB of data, $0.75 per SMS, and $3.00 per minute of calls.
All in all, even Telstra recommends that you go for one of the roaming packs, as pay-as-you-go roaming can quickly become very expensive.
Whenever you go abroad with your Telstra mobile plan, you’ll get a message informing you of the roaming options, so make sure to pick up a roaming pack to avoid excessive pay-as-you-go charges.
How to get Telstra international roaming in Japan
The process of getting a roaming plan depends on the Telstra service you choose to use. Here are step-by-step instructions for each roaming option.
- Activate a Day Pass:
- Open the Telstra app or website and go to the Services tab.
- Open the Extras menu.
- Tap on the International Roaming option.
- Toggle International Roaming Day Pass to the on position.
- It takes up to two hours for the Day Pass to become active.
- Get a prepaid roaming pack:
- Open the Telstra app or website and go to the Services tab.
- Open the Extras menu.
- Select the roaming pack you want to buy.
- Complete your purchase.
- You can also call +61 439 12 5109 to have an agent help you get your roaming pack.
- Use pay-as-you-go roaming:
- You will automatically be charged pay-as-you-go rates whenever you use Telstra services abroad without having a Day Pass or a roaming pack.
If you plan on using a prepaid roaming pack, make sure to buy it once you land in Japan. These packs become active the moment you buy them, so you’d be wasting your validity period if you bought it before the trip.
For international day passes, they activate automatically with data usage, calls, or texts abroad. So as long as the service is activated on your Telstra account, you can simply turn on data roaming and enjoy your time worry-free.
No matter which roaming option you choose, you’ll need to turn on data roaming on your phone to be able to use mobile internet abroad. You don’t need to do anything extra to use your mobile number for calls and text messages.
