Coles Mobile review: Our verdict
Coles Mobile offers decent value for money if you're after a month-to-month subscription plan or a prepaid option (including long expiry).
The main caveat is it may not be your telco of choice if your data needs for the month fall under the 10–11GB mark.
Having said that, Coles Mobile could be right for you if:
You're keen on a mobile app to help you manage your plan when you're out and about and want to quickly check on your data usage.
You want to make unlimited international calls to any of the countries on Coles Mobile's list.
Just keep in mind that:
The perks are better on Coles Mobile's month-to-month plans, but these will also cost you more each month. For example, the data rollover limit is 500GB on prepaid plans as opposed to 1000GB on month-to-month plans. You also get unlimited international calls to 15 countries as opposed to 22.
Data on your month-to-month plan will only roll over if you've set up auto-renew.
"Coles mobile is one of the cheapest 1 year prepaid mobile plans. It's easy to buy in any Coles supermarket and it comes with Coles mobile app for registration. You can recharge online or in-store. What I like about it the most is that you can also earn Flybuys points through in-store recharge. Only let down is it's on the Optus network which has less coverage in other areas."
The cheapest way to sign up to Coles Mobile is through its long expiry plans. For example, its $195 plan works out to be $16.25 a month for roughly 11GB of data.
Its 28-day prepaid plans are mostly on par with what other providers offer for similar data limits. Just remember that a 28-day expiry means you'll be paying 13 bills over the year instead of 12.
Lastly, the subscription plans offer good value for money based on our $1 per GB benchmark. These will work in your favour if you have high data needs.
Things to watch out for
All plans come with auto-recharge activated by default. Depending on your preferences, this can either be a pro or con, but you can turn it off if you choose.
Coverage
Coles Mobile offers access to Optus's 4G network, which is the second largest network in Australia.
Optus covers 98.5% of the Australian population.
You'll get the same coverage as Optus itself.
Some people in rural or regional Australia might find the coverage spotty compared to Telstra's network, which covers 99.8% of the population.
Customer service
Need help? You can reach Coles support any day of the week:
Ring the call centre from 9am–8pm on weekdays or 10am–6pm on weekends (AEST).
Start an online chat via the Coles website during call centre hours (might get a faster response).
Chat to customer support via the Coles Mobile app, which also lets you manage your account.
Keep in mind that while there are physical Coles stores around to purchase the SIM card, don't expect to find any proper tech support in-store.

Bonus features
Other bonus features or perks that stay consistent include:
🔄 Data rollover
Data rollover is helpful when you don't always use the same amount of data every month.
You can bank up to 1000GB on its month-to-month plans and up to 500GB across all prepaid plans.
🌏 International calls inclusions
All Coles Mobile prepaid plans let you make unlimited calls and texts to 15 countries, while its month-to-month plans come with unlimited calls and texts to 22 countries.
Alternatively, you can purchase $5 or $15 worth of credit for international calls, which will last you 14 days or until you use it up.
➕ Data add-ons
Coles Mobile offers the option to add on data if you run out. You can purchase 3GB for $10 with a 5-day expiry on its month-to-month plans.
On prepaid plans, you can pick up 500MB of extra data for $5 with a 7-day expiry or 3GB for $15 with a 30-day expiry.
➕ International roaming
You can enable international roaming for $25. All usage is charged at a pay-as-you-go basis and lasts for 30 days. Unused credits of up to $500 can be rolled over if you recharge before expiry.
Ready to sign up to Coles Mobile?
Once you've decided which Coles plan you're after, you can easily sign up online or grab a SIM at your local Coles supermarket if that's more convenient for you. SIM delivery is free via standard postage, but can take up to 8 business days to arrive at your door.
What if I want to keep my current phone number? You can choose to keep your current number when you activate your new Coles Mobile SIM card, which is done via the Coles website.
Coles Mobile will transfer your number over usually within 15 minutes, but it could take a couple of days.

Hi Beele,
Thank you for reaching out.
In most cases, SIMs that were not activated do not expire. You may want to check with Coles when you purchase the SIM card to check if it expires when not activated.
Once activated, the SIM will however expire if you have not recharged it after 186 days from your credit expiry.
Hope this helps! 😊
Kind Regards,
Mai

I have bought a Coles $180 sim card. It doesn’t work! Coles don’t have any help lines and put me onto Optus. Optus say its not their product and won’t help activate the sim. Coles won’t refund me. Absolute rip off. No support and the product doesn’t work.

Hi Wayne,
I’m sorry you’ve had such a bad experience! What is the problem exactly? Did the SIM card not register in your phone, or was it missing credit? Unless it’s a network issue, Coles should be the ones to talk to about resolving your issue.
Regards,
Matt

SIM card not registered after 28 hours! took the sim back to Coles with receipt and they refused to refund or give me a new sim. Acted like they knew nothing about what they sell.

Hi Wayne,
Thanks for your inqury.
Just to clarify, what happened when you went to activate your new SIM on the Coles Prepaid website? Have you tried calling the Coles Mobile support team on 1300 644 741?
Regards,
Matt
WayneFebruary 27, 2018
Nothing! It says its still activating after registering at 11am yesterday. So no phone. Coles support team phone is just a redirect to Optus who refuse to accept its their SIM

Ah, that’s tremendously frustrating! I’m afraid I can’t offer any better advice than attempting to escalate the call up Optus’ support chain. A higher-up may be better equipped to deal with this situation.
