Simify

Simify is an Australian travel connectivity provider operated by SimsDirect Pty Ltd, offering travel SIM cards and eSIMs for Australians travelling overseas. The company began selling travel SIM cards and expanded into eSIMs as travel demand grew.

Today, Simify offers eSIMs covering 190+ countries, with both unlimited and fixed-data options available depending on the destination. Its plans are designed for travellers who want to avoid international roaming fees while keeping their regular Australian number active.

Pricing

Simify offers pricing in multiple currencies, including AUD, USD, CAD, NZD, EUR, GBP, and JPY.

Pricing on Simify varies depending on whether you use an eSIM or a SIM card. For our comparison, we’ll focus on the eSIM service with unlimited and limited data plans.

For destinations with unlimited data packages, such as Asia, eSIM pricing starts from AUD $37.80 for 7-day packages and reaches AUD $395 for 180 days.

Limited data pricing depends on the destination and the amount of data you choose. For example, a 5 GB plan for 7 days in Japan costs AUD $29, while a 100 GB plan for 90 days can cost up to AUD $239.

Because Simify regularly changes its plan range and pricing, check the destination-specific product page for the latest AUD price before purchasing.

Coverage

Simify offers eSIM coverage in 190+ countries worldwide. Its plans include country-specific and regional options covering destinations across Europe, Asia, Africa, the Middle East, Oceania, and the Americas.

Popular regional options include:

• Europe & UK: A regional eSIM covering multiple European destinations and the UK.

Subscriptions

Simify does not currently offer a monthly eSIM subscription comparable to Holafly Plans. Instead, it sells prepaid travel eSIMs with fixed validity periods, including plans lasting up to 180 days on selected destinations.

Ease of use

Considering what Simify offers with their eSIMs and SIM cards, here’s what makes their service easy to use:

• Clear information: The information for every eSIM is pretty clear on its product pages. Before purchasing, you can find information related to data speed, coverage, compatibility, and other similar features on websites such as Google reviews and Reddit.
• Easy installation: Simify has an easy activation and installation process. But there’s no option for automatic activation; everything has to be completed manually using a QR code.
• Customer support: Customer support is good and quickly solves doubts regarding eSIM usage, but this is unavailable 24/7 as it only works from 10 AM to 5 PM AEDT.
• Hotspot: Hotspot and tethering are supported on selected plans, including Simify’s fixed-data eSIMs. Check the individual plan before purchasing.
• Keep your number: Simify’s data eSIMs allow you to keep your regular Australian SIM active for calls, SMS, and one-time passwords, although your Australian provider may charge roaming fees for calls or messages.

App

Simify offers a mobile app for iOS and Android. Travellers can use the app to access their eSIMs, install compatible eSIMs, view installation instructions, and track data usage.

For compatible devices, the app can also handle most of the eSIM installation automatically. On iPhone, automatic installation is supported on iOS 17.4 and later, while Simify provides manual installation instructions for older versions.

Pros and cons

• Pros:
  • A variety of limited and unlimited data plans are available
  • Coverage in 190+ countries
  • 24/7 customer support
  • Variety of payment methods
  • Hotspot and tethering supported on selected plans
  • Some eSIMs include a phone number, including SMS and phone calls
• Cons:
  • Plan features and hotspot allowances vary by destination

  • No monthly subscription comparable to Holafly Plans
  • Pricing and data allowances vary significantly between destinations

Holafly vs. Simify: The verdict

Now that we’ve compared the main features of Holafly and Simify, which one is better for Australian travellers?

Holafly is a strong option for travellers who prioritise unlimited data and flexible trip lengths. Its travel eSIMs cover 200+ destinations, and the provider offers 24/7 multilingual customer support, an easy-to-use app, and flexible validity periods.

Holafly also includes Always On with eligible eSIMs, providing 1 GB of backup data every 30 days at no extra cost. As long as the eSIM remains installed and meets the applicable requirements, this backup data can help you stay connected in an emergency, such as booking transport or accessing maps.

Simify is also a solid choice for Australian travellers, particularly if you want a choice between unlimited and fixed-data plans. It offers coverage in 190+ countries, 24/7 support, and a mobile app for managing and installing eSIMs.

Ultimately, the better option depends on your travel needs. Simify is a solid choice if you prefer fixed-data options, a wide range of destinations, and an Australian-focused travel eSIM provider. But if you prioritise unlimited data, flexible plan durations, multilingual 24/7 support, and Always On backup data, Holafly may be the better fit.
