Make sure your phone supports eSIM cards.
Purchase your eSIM plan via the Simify website.
Receive a QR code via email.
Activate the eSIM card by scanning the QR code on your other devices.

1. Pricing and data packages

Simify offers unlimited data plans and local SIM options across many destinations. Prices vary by location and duration.

For example, if you’re traveling to Japan, you can choose:

100GB (90 days) at $144 ($1.44/GB)
60GB (60 days) at $99 ($1.65/GB)
45GB (45 days) at $81 ($1.80/GB)
30GB (30 days) at $59 ($1.97/GB)
20GB (30 days) at $45 ($2.25/GB)
10GB (30 days) at $23 ($2.30/GB)
5GB (7 days) at $18 ($3.60/GB)
Unlimited data for 7, 15, 21, 30, 45, 60, and 90 days starting at $3,85 per day

There’s no option to extend or top up an existing plan — once it expires, you’ll need to purchase a new eSIM.

3. Network coverage and quality

Simify offers eSIM coverage in over 150 destinations, including Europe, the UK, Japan, South East Asia, New Zealand, the USA, Canada, and Mexico.

However, it does not provide city-specific eSIMs (for example, Bali or New York).

It also provides regional plans that combine multiple countries into a single package like:

Europe and UK: Covers major destinations like France, Germany, Italy, Spain, and the UK
USA, Canada and Mexico: Single international SIM card for North America
China, Hong Kong, Macau and Taiwan: Designed for travelers visiting multiple locations in Greater China

Simify’s customer support team is available via email and live chat from 9 AM to 8 PM AEST. If you experience connectivity issues, you can check their online guides.

Simify offers a 100% money-back guarantee under specific conditions, such as:

The eSIM card was never activated.
The device was found incompatible after purchase.
Internet connection issues due to local network problems.

Refunds are not guaranteed for issues caused by early activation, data roaming misconfigurations, or locked devices.

Assistance is available through email and live chat, where travelers can reach out for help with installation, network issues, or general inquiries.

If you need help outside of support hours, the website includes setup guides and FAQs to assist with common troubleshooting steps.

If you’re tech-savvy and frequently write about data services, this could be a great opportunity.

Simify also offers a referral program where users can earn $10 in cash for referring a friend, while the referred friend enjoys a $10 discount on their purchase.
