See the exact price for your dates
aloSIM and VoaSim both solve the same problem — getting online abroad without roaming bills — but they price it differently. aloSIM follows the GB model: you pick a country or region, pick a data bundle, and top up if you run out. VoaSim follows the day model: you pick how many days you travel and data is unlimited, with no cap and no throttling.
This is a comparison of business models, not a lab speed test. Both brands run on local partner networks, so real-world speed depends on the country, the tower and your phone. What you can compare honestly is how you pay, what happens when data runs low, and who answers when something breaks.
How each brand works
aloSIM (Canada-based) is an app-first eSIM store. You browse local, regional and global packages sold by GB, buy in the app, install the QR code and monitor usage there. Validity and allowance are printed on each package, so a 3 GB / 15-day plan means exactly that: when the GB are gone, you top up.
VoaSim removes the GB variable. You choose 5, 7, 10, 15, 30 or 60 days and the data is truly unlimited — no cap, no speed throttling, no hidden fair-use clause. The price depends on the destination; check yours in the simulator. Coverage reaches 160+ destinations on every continent, and the Europe plan covers 39 countries with one eSIM, including the UK, Switzerland, Turkey, Norway and Iceland.
Both are data-only. Your physical SIM and your phone number stay active, so WhatsApp keeps running on your number. Always check the current package terms on each brand's official site before you buy.

Where aloSIM may be the better pick
Be honest about your usage. A GB-based eSIM can win in three cases:
- Light data trips. A weekend where you only need maps, messages and a boarding pass may need very little data. A small package can come in under a flat day rate.
- Island Caribbean. VoaSim has no coverage right now in the Dominican Republic, Cuba, Jamaica, the Bahamas, Aruba or Curaçao. Puerto Rico works because it runs on US networks. For those islands, check aloSIM or another provider.
- App-centric buyers. If you like watching a usage bar and topping up inside an app, that workflow is aloSIM's home turf.
Check aloSIM's official site for current packages, validity and tethering rules — those terms change and only the brand itself can confirm them.
Decision checklist
| What matters to you | Better fit |
|---|---|
| Streaming, video calls, heavy maps use | VoaSim (truly unlimited) |
| Very light usage on a short trip | GB package like aloSIM |
| One eSIM for 39 European countries | VoaSim Europe plan |
| Island Caribbean destinations | aloSIM or another provider |
| Predictable cost, no top-ups | VoaSim flat day price |
| Company invoice by email in USD | VoaSim |
| Hotspot as a must-have | Confirm with support first, either brand |
Sharing your connection (hotspot or tethering) is not allowed: the local carrier may block your line. Each traveler uses their own eSIM, and 2 or more eSIMs get an extra 10% off. More side-by-side reading in our comparisons and best eSIM picks.
Support, guarantee and what happens if it fails
The moment that separates eSIM brands is the one where the phone shows no signal at 11 p.m. in a foreign airport. VoaSim answers by email at hola@voasim.com and on-site chat, with human support — WhatsApp optional if you leave a number at checkout. If the eSIM will not connect and support cannot fix it, you get a 100% refund.
There is also a free tool, eSIM Rescue, that diagnoses an eSIM with no signal from any brand — including one bought elsewhere. It checks the usual suspects: roaming toggle off, wrong data line selected, missing APN, carrier-locked phone.
aloSIM handles support through its own channels and refund terms; read them on its site before buying. More on how we operate is on the trust page.
Install before you fly
With VoaSim, the QR code arrives by email within minutes of payment, plus a step-by-step guide for iPhone and Android. Install it at home, on Wi-Fi, then leave the eSIM line off until you land. The validity clock starts at the eSIM's first connection to a network at the destination, not at purchase — so on Android, do not switch on the eSIM's data before the trip.
Compatibility: iPhone XR or newer, Samsung Galaxy S20 or newer, Google Pixel 3 or newer, and most phones released from 2020 on. Universal test: dial *#06# and look for an EID. Carrier-locked phones must be unlocked first. VoaSim does not sell physical SIM cards.
One last note for cruise travelers: an eSIM works on land, at ports, not at sea. See the setup guides for the full walkthrough.
Why trust VoaSim?
Registered company with an invoice on every purchase, USD payment via Stripe with no hidden fees, 24/7 human support and a guarantee: if the eSIM will not connect and support cannot fix it, you get 100% back.
