If you're about to travel overseas and you've booked your tickets, hotels and entertainment, the next order of business is working out how to use your phone overseas.
On the vast majority of mobile plans in Australia, you can just take your phone and use it, but each call can cost up to $5/minute, and data can also quickly add up to the price of a small car.
We've put together this guide to explain how roaming charges work and to help you avoid any bill shock while you're overseas.
Depending on your reasons for travelling, different roaming options on SIM cards will be better tailored to your needs.
Your 4 options are:
For example, if you're just on holiday, then you might just want to be able to post pics to Instagram and FaceTime with Mum, in which case you could just get a cheap SIM card at your destination.
If you're travelling around a few different countries, a travel SIM might be better.
But if you're a business traveller who has to be contactable 24/7, you'll probably need to keep your number (or put on call forwarding).
It's also one of the cheapest, tied with Optus.
Its $40 plan strikes the right balance between generous data and value to cover the extra you might use while travelling (for example, video calls home, uploading photos and videos to make friends jealous back home).
| Response | Male | Female |
|---|---|---|
| Keep current plan and use international roaming | 12.43% | 11.07% |
| Buy a local SIM when I arrive | 11.32% | 9.84% |
| Buy a travel SIM before I fly out | 7.61% | 7.56% |
This is the most expensive option, and one we would only recommend under dire circumstances, or if someone else (like your boss) is paying.
If you're not with a major carrier like Telstra or Optus, you'll need to double-check they offer roaming, and you'll also need to confirm if your country is covered.
Checklist for international roaming:
Does your carrier support roaming?
Is the country you're visiting supported?
Check the call and data rates. This can vary wildly, starting at $1/MB, with some carriers charging $3/MB.
The big 3 telcos have sliced the world up into "zones" of countries that dictate how much you'll spend on roaming while you're there. The "zone" your destination is in makes a huge difference in price.
You can see on the map below how the roaming costs break down from the major providers: Telstra, Optus and Vodafone.
If you're only going on a short trip for a few days or want to keep your Aussie phone number while you're away, then a travel pack is the best bet. These packs differ depending on the provider, but usually come with a set amount of call and data inclusions for selected countries.
Any usage outside of these countries will be charged at standard roaming rates though, so it's good to double check that the places you're going to are covered.
The big 3 Australian telcos have roaming packs with varying generosity:
Telstra only offers 1 roaming add-on called its International Day Pass on its Upfront plans, and is the least generous of the major telcos.
| Calls | SMS | Data | Price |
|---|---|---|---|
| Unlimited | Unlimited | 500MB/day | $10/day |
If you go over your allocated data amount, additional data will cost you $10/GB.
Optus splits its roaming offers depending on what type of plan you're after: postpaid or prepaid.
For Optus postpaid plans, you have 2 options of roaming add-ons that apply to countries on their Zone 1 destination list:
| Calls | SMS | Data | Price |
|---|---|---|---|
| Unlimited | Unlimited | 5GB/day | $5/day |
| Unlimited | Unlimited | 35GB/7 days (equivalent to 5GB/day) | $35/7 days (equivalent to $5/day) |
Once you use up your data or the time period passes you'll need to pay for another add-on.
Zone 1 destinations for Optus include:
Optus' Prepaid Roaming add-ons, on the other hand, are more or less the same price with fewer calls and text included. You have options for calls, texts and data as well as data only.
| Add-on | Calls | SMS | Data | Price |
|---|---|---|---|---|
| 1-day Roaming (Talk, text and data) | 100 minutes | 100 texts | 1GB/1 day | $5/1 day |
| 7-day Roaming (Talk, text and data) | 700 minutes | 700 texts | 7GB/7 days | $35/7 days (equivalent $5 per day) |
| 14-day Roaming (Data only) | 0 | 0 | 10GB/14days (equivalent to 0.71GB/day) | $20/14 days (equivalent to $1.43/day) |
The catch is that while the talk, text and data plans include Zone 1 destinations the data-only add-on only works in 10 destinations: Mainland China, Hong Kong, Indonesia, Japan, Malaysia, New Zealand, Singapore, Thailand, UK and USA.
Vodafone has arguably the best postpaid roaming offer available across all its plans, and works quite differently to the rest.
Instead of buying an add-on with a set amount of inclusions, you'll just need to pay an extra $5 a day and you can use your mobile plan as though you were in Australia, with all the same data and call inclusions.
That means if you're on a Vodafone mobile plan that usually gets you 40GB for $40 each month, you'll be able to use 40GB overseas for $45 ($40 as your usual plan price, plus an additional $5 for roaming).
It works in more than 100 countries, so chances are good that you'll be covered.
Eligible countries include:
If you're on Vodafone prepaid, you can pay $5 a day to get 200MB of data per day, though there are incentives when you buy days in bulk – $35 gets you 2GB to use over 7 days.
Whether you travel a lot or just want a SIM that can take you to multiple countries, there are a couple of retailers in Australia that can sell you just the thing you need.
Both SIM Corner and FlexiRoam sell SIMs that cover whole continents or particular bundles of countries, with credit lasting 7–60 days and prices starting at $30. These typically work out to be cheaper than paying as you go on your regular mobile plan.
This is usually the cheapest option if you're only visiting 1 country for more than a few days. You might not be able to call home as readily (depending on the offer from the telco over there), but you will likely have more data for cheaper, and a local mobile plan that you can use to call hotels and taxis.
If you do choose this route, here are some tips for a smooth process:
If you're travelling for fun, why not just stay in the moment and save some money? You can have your phone in Airplane Mode and use it to take photos, and then just upload over Wi-Fi at the hotel or a cafe.
If you need to call for help, your phone might still be capable of making an emergency call to 000, 111, 911, etc., depending on your country and phone (that's what "SOS Only" means).
Once you've decided which type of roaming option you're after, consider the following to really keep your usage low and avoid any hidden costs:

You can get international roaming on most of Telstra’s postpaid mobile plans from just $5 a day.
You can roam globally using a prepaid phone plan, but it’s not always cheap. Here is what you need to know to minimise your costs.

Do we purchase SIM cards in France or pre pay in Melbourne before leaving?
Hi Rod,
As finder is a financial comparison website offering general advice, we are not permitted to provide our users with personalised financial advice or make product recommendations.
However, we do help guide you through the process of comparing your options.
You may find useful information on roaming with your existing mobile plan on our page for prepaid or postpaid.
I would also want to advise that you learn more about how to use prepaid SIM cards while traveling around the European Union.
I hope this helps.
Cheers!

Travelling to Dubai, Portugal, Spain, UK and Iceland from Australia from 13th September 2017. Best plan/card to use. Can I keep my own number while travelling?
Hi Anne,
Thanks for your inquiry.
If you have an existing contract mobile plan, it’s always wise if you know you’re going to travel to purchase a roaming allowance from your contract provider rather than simply enabling roaming, because the associated costs can be quite high. Please feel free to read more about global roaming and see how it can help you save money in your travel.
You can also do roaming with a prepaid plan. It minimizes the possibility of outright bill shock simply because you can’t spend more than the amount you’ve already given your telco before you travel. You can get more helpful info on this through our roaming prepaid guide.
Hope this information helped.
Cheers,
Rench
