Understanding your data cap

The 50MB/month data cap is designed specifically for GPS tracking. It’s more than enough for continuous tracking, even with regular location updates.

Instead of paying for a chunk of data, you’re paying for the plan duration. If your device uses more than 50MB in a month, it will lose data until the next month starts. If that happens, we can get you back online for an additional cost.

Need more than 50MB a month? Just reach out to our Support Team and we’ll find a plan that works perfectly for you.

FAQs

SentriSIM is designed for most 4G GPS trackers and IoT devices. It is not compatible with mobile phones, tablets, 4G dash cams or other devices requiring a larger data plan.

The intelligent SIM utilises data roaming to automatically connect to the strongest available signal from Telstra, Optus, Vodafone or other major carriers. You’ll get continuous coverage across all of Australia.

There are no contracts, hidden fees or cancellation charges. You just pay for the plan duration you choose – monthly, 6-month or 12-month. 

Plans automatically renew at the end of each term, but you can cancel anytime before your next renewal date. Your plan will stay active until the end of your current paid period. 

Once your plan expires, the SIM will stop working unless you reactivate it. If you need to reactivate after cancellation, just get in touch with our Support Team – sometimes a new SIM card may be required. Keep in mind, we don’t offer pro-rata refunds for unused time.

The SentriSIM card arrives pre-activated and ready to use! Simply insert it into your compatible device with no further setup or ID verification required.

Yes, we can help you reactivate your SIM if needed!  In some cases, a new SIM card may be required. Just reach out to our Support Team and we’ll sort it out for you.

You can start with a monthly plan and switch to a 6 or 12-month option anytime for better savings. Your current plan will stay active until it expires, and while it automatically renews, you can cancel whenever you want.

Our expert support team is based in Perth and Sydney, Australia, ensuring you receive timely local assistance.

The 50MB per month data limit is designed for GPS tracking and IoT use. It’s enough for regular tracking, even with frequent updates. Since you're paying for the plan duration, not a set amount of data, most users won’t hit this limit.

If you do go over 50MB, your device will temporarily stop transmitting data until the next month begins. We can get you back online for an extra cost if needed. If your setup requires more than 50MB a month, like software updates or custom use cases, reach out to our Support Team and we’ll help you find a solution.

To help you monitor your data usage, we’ll send notifications when you reach 50%, 85% and 100% of your monthly data limit. These alerts will be sent to the specified email address within 48 hours of reaching each threshold.

You can choose to:

  • Opt out of these notifications at any time
  • Provide a specific email address for monitoring (e.g., a business contact or dedicated tracking team)

These notifications help you stay on top of your usage. If you need higher data limits or have special requirements, contact our Support Team to discuss custom options.

The SIM comes as a 3-in-1, including Standard, Micro and Nano sizes to fit a wide range of compatible devices. Just pop out the size you need.

SentriSIM gives you coverage across Australia. It automatically switches between networks to keep you connected whether you’re in the city or out in remote areas. If you lose connection, most GPS trackers will sync data as soon as you’re back in range.

You can reach us by phone, email or live chat during business hours. Our expert teams in Perth and Sydney are here to help you.
