My experience with Superalink
I went with the Indonesia 5GB / 4-day plan for $7.10 (you can get 15% off this, or any Superalink plan, with our code NOMADWISE). Checkout on the website was straightforward, and after purchasing, I received the QR code by email.
Setting up the eSIM was simple. I followed the instructions to activate it on my phone, and one thing I'll flag honestly: it didn't connect straight away. I was probably expecting it to work instantly like some other eSIMs I've tested, but it took a few minutes longer than expected to activate. I was just about to restart my phone when it kicked in and started working. Not a dealbreaker, but worth knowing so you don't panic if it doesn't connect the second you scan the QR code.
💡 A quick tip from experience: even when setup is fast, take one minute before to remove old/inactive eSIMs and rename the new one during or after you've installed it. If you travel a lot and stack multiple eSIM profiles, this saves you from unwanted bugs and confusion later.
One thing worth noting: Superalink doesn't have a dedicated app (unlike some competitors). Everything is managed through the website, from purchasing to checking your QR code to getting support. Personally, I prefer this. I like to keep my phone minimal, so not having to download another app was a plus for me.
Support-wise, Superalink offers 24/7 help via WhatsApp, which is a nice touch for travellers already using WhatsApp as their main messaging app. I didn't need to contact support during my test as there were no issues once the eSIM was up and running, but their WhatsApp support line is clearly accessible from the website.
Superalink internet speed (test)
I used my iPhone 15 Pro and as always on Nomadwise, the speed was tested using the website speedtest.net.
The results were genuinely impressive: 96.6 Mbps download and 51.2 Mbps upload, with a ping of 143 ms and just 5 ms jitter. That's strong performance for a travel eSIM and easily fast enough for browsing, Google Maps navigation, messaging, and hotspotting.
The speedtest also scored well across the board for web browsing, video streaming, and video calls. Only gaming showed a slightly mixed result, likely due to the higher ping (143 ms), which is typical for roaming eSIMs.
It's worth noting that Superalink's plans offer 5GB of high-speed data per day, after which speeds are throttled (reportedly to around 128-384 kbps according to third-party reviews, or up to 1024 kbps on some plans). For a 4-day trip, 5GB per day was more than enough for my needs: catching up on emails from cafes, navigating around Bali, messaging, and general browsing.
Bali has decent mobile infrastructure in the more populated areas like Seminyak, Canggu, and Uluwatu, but coverage can get patchy in more remote parts of the island or on other Indonesian islands. My test was mainly in and around these popular areas, so I can't speak to how Superalink would perform in more rural parts of Indonesia. For a typical Bali trip though, I had no complaints.
Superalink set up process
The setup process was straightforward and took just a couple of minutes from start to finish. Superalink currently offers setup via their website only (no dedicated app).
Setup via website (QR code install):
- Buy your plan on the Superalink website.
- Receive the QR code by email (delivery is instant).
- Scan the QR code with your phone and it opens your cellular/eSIM settings.
- Confirm adding the eSIM, then set it as your mobile data line.
- Turn Data Roaming ON for the eSIM line.
- (Optional but smart) Rename the eSIM to something like "Superalink Indonesia".
Your plan activates once you connect to a local network at your destination, and Superalink gives you 180 days from purchase to activate. So you can buy well in advance of your trip without worrying about the clock starting early.
If it doesn't connect right away, here are some general quick fixes you can try before contacting support:
- Toggle airplane mode on/off
- Restart your phone
- Make sure the eSIM is selected for mobile data
- Check that Data Roaming is enabled
- If your phone is set to "5G only", switch to automatic / LTE+5G
Is Superalink a good eSIM?
Based on my test in Bali, I'd rate Superalink as a solid budget-friendly travel eSIM, especially if you're travelling in Asia where their coverage and pricing are particularly competitive.
What I really like about Superalink
- Very affordable pricing: Superalink is consistently one of the cheapest eSIM providers on the market. I paid just $7.10 for 5GB over 4 days in Indonesia, and plans start from around $4.63. For budget travellers or digital nomads watching their expenses, this is a real standout.
- Even cheaper with our code: Superalink gave Nomadwise readers an exclusive 15% discount with the code NOMADWISE, which stacks on top of their already low pricing and works on every plan.
- Generous daily data: The 5GB/day allowance is plenty for most travel needs. Browsing, navigation, messaging, and even some video calling or hotspotting all worked fine.
- Hotspot/tethering included: All plans support tethering with no restrictions, which is great if you need to share data with a laptop or travel companion.
- 180-day activation window: You can buy your plan well ahead of your trip and it won't start counting down until you actually connect at your destination. That's one of the longest activation windows I've seen.
- Quick WhatsApp support: Their 24/7 WhatsApp support line is convenient, especially in Asia where WhatsApp is widely used.
- GSMA-certified: Superalink is officially certified by the GSMA, which adds a layer of credibility for a newer provider.
- Strong speeds in Bali: I got nearly 97 Mbps download in my test, which is impressive for a budget eSIM and more than enough for remote work or everyday travel use.
What could be better
- Data-only: No calls or SMS included, so you'll rely on WhatsApp/FaceTime/Signal/etc. for calling.
- Speed throttling after 5GB/day: Once you hit the daily cap, speeds drop significantly. If you're a heavy data user (streaming, large uploads), this could be limiting.
- No dedicated app: Everything is managed via the website. While this keeps things simple, some travellers prefer having an app to quickly check remaining data or top up. Personally, I didn't mind, but it's worth knowing.
- Activation wasn't instant: In my experience, the eSIM took a few minutes to connect after installation. It wasn't a major issue, but if you're used to eSIMs that work the second you scan the QR code, don't panic. Give it a moment.
- Trustpilot score is mixed: With a 4.1/5 rating from around 50 reviews, Superalink has mostly positive feedback but some users have reported issues, including one reviewer who found their "unlimited" plan had a 5GB daily cap they weren't expecting, and another whose eSIM stopped working mid-trip. Worth being aware of as a newer, less-established provider.
- "Unlimited" labelling: Superalink markets plans as "unlimited" but they come with a 5GB/day high-speed cap before throttling. This is common in the eSIM industry, but it's worth knowing what you're actually getting.

Overall summary
Superalink is a data-only eSIM provider based in Singapore with coverage across 150+ countries, and it stood out in my test for its combination of affordable pricing and genuinely strong speeds. I used the Indonesia 5GB / 4-day plan on an iPhone 15 Pro during a trip to Bali and got nearly 97 Mbps download, which was easily enough for emails, navigation, messaging, and general browsing from cafes and around the island.
Pricing is where Superalink really shines. I paid just $7.10 for my plan, and they're consistently among the cheapest eSIM providers, especially for Asia. The 5GB daily high-speed allowance with throttled speeds after is generous for most travellers' needs, and the 180-day activation window gives you plenty of flexibility for trip planning.
The main things to be aware of: it's data-only (no calls/SMS), the "unlimited" branding comes with a daily speed cap, activation took a few minutes longer than I expected, and as a newer provider, there's still a smaller pool of long-term user reviews compared to more established names. That said, their GSMA certification and responsive WhatsApp support are reassuring.
If you want to try them out, you can use our code NOMADWISE at checkout for 15% off any Superalink plan.
One nice extra: Superalink donates a small amount from every purchase to Cointree, supporting underprivileged children's education. A small but positive differentiator from other providers.
