What is Simify, and how does it work?

Simify is an Australian travel connectivity company operated by SimsDirect Pty Ltd. The business started in Sydney in 2018, selling physical travel SIM cards under the SimsDirect name before expanding into eSIM technology and adopting the Simify brand.

A travel eSIM works like a digital version of a physical SIM card. Instead of swapping out the SIM in your phone, you download a mobile plan onto a device that supports eSIM technology. Simify offers connectivity in more than 190 destinations across 150 countries, with country-specific, regional, and global plans. Its Global eSIM currently covers 128 countries.

The service connects your phone to one of Simify’s local partner networks once you reach your destination. Depending on the plan and location, that can mean 4G or 5G connectivity.

Simify has built up a substantial customer base. As of September 2026, its Australian Trustpilot profile had a 4.8/5 rating from more than 3,400 reviews. Most reviewers praised straightforward connectivity and responsive support, although some reported difficulties during installation or initial activation.

Simify — pros and cons at a glance

How to install and activate your Simify eSIM

Simify has simplified its setup process through its app, but checking a few things before departure can save you from troubleshooting at the airport.

1. Check your phone before buying. Confirm that it supports eSIM technology and is carrier unlocked. You can also check the list of eSIM-compatible devices before purchasing.

2. Choose your destination and plan. Buy a fixed-data or unlimited Simify plan for the country or region you’ll visit.

3. Install the eSIM before departure. Simify recommends installing the eSIM while you still have a reliable internet connection. Make sure flight mode hasn’t cut off your Wi-Fi or mobile data during installation. Installing the eSIM doesn’t normally start the travel plan because validity begins when your phone connects to a supported network at your destination.

4. Keep the Simify eSIM switched off until you need it. On some phones, installation can automatically turn the line on. If you haven’t reached your destination yet, check your mobile settings and switch your eSIM line off.

5. Activate your eSIM line after arrival. Turn on the Simify line, select it for mobile data, and enable data roaming for the Simify eSIM.

6. Protect your Australian SIM from international roaming charges. Before switching mobile data to Simify, make sure data roaming is off for your Australian SIM and disable automatic mobile data switching. You can keep your Australian local SIM active to receive calls, text messages, and verification codes, but your carrier may charge you for roaming activity. 

You also need an internet connection during installation, so don’t try to set up the eSIM for the first time while your phone has no Wi-Fi or mobile data connection. If it doesn’t connect after arrival, Simify recommends toggling airplane mode on and off or restarting the phone.

Simify eSIM review: Pricing and plans

Simify offers fixed-data and unlimited plans for individual destinations as well as regional options. The Europe & UK plan, for example, covers 51 countries, while the Global eSIM currently covers 128.

Fixed plans generally range from smaller short-trip allowances to 100 GB plans lasting up to 90 days. Simify’s unlimited eSIM plans let you choose the number of days instead of fixed data limits, although fair-use restrictions apply.

Pricing varies by destination. As of September 2026, the standard Simify price for 10 GB over 30 days was AU$49 for destinations including Japan and the USA, as well as its Europe & UK regional plan. Simify regularly runs promotions, so checkout prices can be lower.

Here’s how some equivalent Saily plans compare. Saily displays these plans in US dollars, so the approximate Australian dollar values below use the exchange rate available on September 27, 2026, and may change.

This comparison highlights one reason to check the exact destination rather than assuming one service provider is always cheaper. Saily was substantially cheaper for Japan, the USA, and the UK at the time of checking, while Simify’s standard Europe & UK plan was slightly cheaper than Saily’s 10 GB Europe regional plan.

Simify also supports Afterpay on its Australian checkout, while Clearpay appears on its UK site.

One detail has recently changed. Fixed Simify plans still don’t offer a conventional data top-up — once the allowance runs out, you need another plan or eSIM. However, eligible unlimited eSIMs can now be extended by adding more days through the Simify app.

Network speed and performance

Actual eSIM speed depends on the local mobile network rather than Simify alone, so results vary significantly by location.

In one independent US test, GadgetGuy recorded typical speeds of about 30 Mbps down and 3 Mbps up while using Simify. The reviewer reported reliable connectivity during a three-week trip, with gaps mainly occurring in areas where the underlying local network had little or no coverage.

That matches how travel eSIMs generally operate. Simify connects to partner carriers rather than running its own network. Its US fixed-data plan, for example, lists AT&T or Verizon, while its Japan products use networks including KDDI and SoftBank.

Cities and major tourist areas should therefore provide the strongest performance. Rural, mountainous, or remote regions may have slower connections or no service at all if the partner carrier has limited coverage there. 

Unlimited data also comes with an important caveat. Simify applies a fair-use policy, meaning unusually heavy usage can result in temporary speed reductions. Simify says these restrictions generally reset by the following day, but it doesn’t publish a universal daily threshold because the rules may depend on the network supplier.

An unlimited plan may be useful if you don’t want to monitor every gigabyte, but “unlimited” shouldn’t be interpreted as guaranteed full-speed data regardless of how much you use.

Customer support

Simify provides support through live chat, email, its online Help Centre, and troubleshooting information in the Simify app.

Customer support is one of the strongest themes in Simify reviews. Trustpilot feedback frequently mentions staff helping users resolve activation and connection problems, although some customers report that getting an eSIM working initially requires several troubleshooting steps.

Simify also offers a money-back guarantee, but the conditions matter. If an unused eSIM turns out to be incompatible with your device, you may qualify for a full refund. Connection problems can also be eligible for a partial or full refund, but Simify asks customers to contact support during the trip and allow the team to troubleshoot first.

Refund eligibility can depend on whether the eSIM has been installed, activated, or used, so don’t simply delete a non-working eSIM from your phone before contacting support.

Is Simify legit and worth it?

Simify is a legitimate Australian travel connectivity provider. The company operates legally as SimsDirect Pty Ltd, has a physical Australian business address, and has accumulated thousands of customer reviews.

The broader sentiment is also positive. At the time of writing, 87% of Simify’s Trustpilot reviews were rated five stars, while 2% were one-star reviews. Positive feedback commonly mentions reliable connectivity, easy installation, and helpful support. Negative comments tend to focus on setup problems or difficulty getting connected immediately.

Feedback on Reddit is more limited but follows a similar pattern. Travelers have reported good performance in destinations including Australia, New Zealand, and the US. The main concern around unlimited plans is the lack of a clearly published universal data threshold before fair-use throttling can occur.

So is Simify good? For travelers who value an Australian provider, larger allowances, or unlimited options, it can make sense. Travelers who only need a modest amount of data may find cheaper alternatives.

Simify vs. Airalo, Holafly, and Saily

The travel eSIM market has become considerably more competitive, with Simify competing against other eSIM services such as Airalo, Holafly, and Saily.

The comparison of Simify vs. Airalo largely comes down to plan structure. Airalo offers a broad selection of fixed and unlimited options and can suit travelers who want smaller plans or more destination choices. You can learn more in our Airalo review and Saily vs. Airalo comparison.

Comparing Simify vs. Holafly is particularly relevant for heavy data users because both providers emphasize unlimited plans. Holafly specializes heavily in unlimited data, although its prices are often higher than fixed-data alternatives. Read our Holafly review or Saily vs. Holafly comparison for more details.

The Saily vs. Simify comparison provides slightly different results. Saily combines fixed and unlimited plans with coverage in more than 200 destinations. It also lets you add plans to an already installed eSIM rather than managing multiple eSIMs. Saily also offers security features such as web protection, an ad blocker, and virtual location, and now has an optional US phone number with calling and texting plans. 

Simify has the advantage if you particularly want one of its longer or unlimited plans and prefer buying from an Australian-founded company. Saily can make more sense if you want lower-cost fixed plans in many destinations, wider destination coverage, built-in security features, or a reusable eSIM.

Verdict: Is Simify eSIM worth it in 2026?

Simify is a solid travel eSIM service, particularly for Australians who want a familiar local brand and the choice between large fixed-data allowances and unlimited plans. Its 4.8 Trustpilot rating, broad destination range, hotspot support, and generally positive real-world testing all work in its favor.

However, it isn’t automatically the best-value option. Some fixed plans cost considerably more than comparable Saily plans, unlimited data remains subject to fair-use restrictions, and all current Simify eSIMs are data only.

For many travelers, the Saily eSIM may be a better alternative. It offers flexible data allowances, coverage in more than 200 destinations, built-in security features, and the option to add a US phone number. You can also keep one eSIM installed and add new plans for future trips.

Download the Saily eSIM app to choose your plan and set up your eSIM before you travel.
