SimCorner vs Telstra Roaming: International roaming is an expensive hassle, whether you are rushing out for a few days or travelling for a few weeks. It comes with country restrictions, data limitations, and capped voice allowances, and fewer constraints mean higher prices.

SimCorner offers connectivity to over 200 destinations at their local, affordable prices with its trusted prepaid model.

As per Canstar Blue 2025 ratings, SimCorner eSIM and Travel SIM have earned a 5-star rating in network coverage, ease of sign-up and activation, and value for money. On the other hand, Telstra international roaming has been rated 4-star. Furthermore, Trustpilot SimCorner Rating by customers is 4.5/5, while Trustpilot Telstra Reviews show customer dissatisfaction with a 1.3/5 rating.

Over 26,000 users have rated SimCorner as 4.85/5 across various renowned platforms. The company also offers international SIMs to cater to the needs of customers whose devices do not support eSIMs.

On the other hand, Telstra global roaming will cost you $15 for 7 days, 2GB of data, if you are a prepaid user; or it will cost you $5-10 per day, depending on your destination, if you are a post-paid user. To add another example, 1GB of data for 7 days with SimCorner Travel comes at $5, but 400MB of data for 3 days with Telstra roaming comes as high as $10.
Value for money? SimCorner is definitely a 5-star winner.

Regardless of whether you purchase Telstra international roaming vs SimCorner, a space for improvement remains common for all. It is better to know upfront about the advantages as well as drawbacks of SimCorner.
Telstra is the biggest local network provider in Australia, known for its extensive coverage and premium services. When it comes to providing services around the globe, Telstra naturally relies on international roaming. As an alternative, SimCorner cuts your roaming costs with its efficient and affordable connectivity model.
With Telstra roaming overseas, you can access your primary Australian number to make calls, send texts, and stay connected on limited data in 161 countries. However, beyond the selected 38 destinations, Telstra roaming plans become expensive, quickly stacking up your bills.
Telstra international roaming offers one prepaid and one post-paid plan only, which are sub-categorised as per validity and zones:
Telstra International Day Pass (Post-paid): Validated for a day (24 Hours Upfront Plans/ 12 Midnight AEST Non-Upfront Plans), Telstra Roaming Day Pass comes for $5 at 7 locations and $10 at 80+ locations. This plan is limited to 2GB of data or no data, depending on the zone, and allows unlimited standard calls and SMS. For post-paid customers, it is the only option available as they cannot buy the comparatively cost-effective prepaid Telstra Travel Pack.
The catch? This Telstra roaming data of 2GB does not cover video calls, FaceTime, multimedia and picture messages, or third-party content charges. For all of these, you will be charged at PAYG rates at $3 per MB.
Telstra Travel Pack (Prepaid): It comes with three sub-plans, all eligible at 38 destinations only, a stark contrast to SimCorner’s 200+ destinations.
The voice allowance isn’t limited to outgoing; it covers incoming calls as well. The plan is only eligible for prepaid customers, just as the Telstra Day Pass only covers post-paid users.
Comparatively, $25 with SimCorner gets you 5GB of data for 30 days. Telstra roaming has no plans beyond 14 days' validity—making long-term travel extremely costly.
Telstra Pay-As-You-Go or PAYG (Post-paid): Applicable only to post-paid users, Telstra roaming charges PAYG for every MB you use, every minute you talk, and every SMS you forward. This plan has the widest coverage across 161 destinations, but it comes at a hefty cost and with eligibility restrictions, as opposed to SimCorner’s easy and affordable global coverage.
PAYG costs $3 per MB, 75c per SMS, and $1.5-5 per minute of call, varying as per the location. Just 100 MB of data can cost you as high as $300, but with SimCorner Europe & UK Travel eSIM, you can tour 50 countries for 30 days with unlimited calls and 30GB of internet—just for $64.
Telstra users, hence, prefer SimCorner to save big by waving off their high roaming costs right at the Australian airport.
There’s no doubt that Telstra is one of the premium providers in Australia and has extensive coverage throughout the country. For international travel as well, Telstra strives to provide the same efficiency and quality. Like SimCorner, Telstra also offers 4G/LTE coverage for most countries and 5G coverage at selected destinations.
While actual speeds fluctuate based on local network and congestion, Telstra roaming data offers users up to 100 Mbps. This speed is sufficient as no unlimited data pack is available with Telstra. Contrarily, SimCorner stands out by delivering unlimited data packages with speeds capped at 150 Mbps.
Since Telstra roaming works on the same SIM you have been using, there is no separate installation, other than purchasing your roaming pack and turning on data roaming in your device. This comes with the downside of the pack getting activated instantly upon purchase, whether you are out of Australia or not, or whether you have turned on data roaming or not. Hence, when you are overseas, you first need to connect to a stable Wi-Fi, then make the purchase from the Telstra app or website.
On the other hand, you can keep your SimCorner eSIM purchased and your account set up (or activated) before you fly. If you wish to activate it overseas, you momentarily need to connect to Wi-Fi and get your eSIM services running with a single click. On SimCorner eSIMs with automatic activation, the services will start on your pre-mentioned date, without the requirement to connect to a local Wi-Fi abroad.
Telstra customer support is available 24/7 with its app, website, FAQs, email, or phone. Support is available through an AI chatbot as well as human help.
If you mandatorily need to connect overseas with your Telstra +61 number for SMS/voice calls, then it is the biggest advantage Telstra holds over SimCorner. But, if you can use a different number temporarily or stick to data-only eSIMs, then you may consider the following pros and cons of Telstra international roaming:
While Telstra users may have more trust in their home provider, SimCorner users also place their trust in the company for its consistent services, authenticity, and security.
Considering all the factors and pros/cons associated with each provider, SimCorner distinguishes itself as a better provider on the international stage against Telstra. For the same services, SimCorner is more affordable and comes with more plans and destination flexibility.
Whether you visit Europe, Asia, or Africa, SimCorner has your back as the best eSIM/SIM card for Australian travellers. You may browse through SimCorner eSIMs or Travel SIM cards (physical SIMs) and select the best plan for your next international trip.
