VoaSim vs aloSIM: side by side

Traveler comparing VoaSim and aloSIM eSIM plans on a phone at an airport gate
Straight answer: VoaSim sells travel eSIMs with truly unlimited data at one flat price per duration: USD 18.90 for 5 days, USD 30.90 for 10 days, USD 61.90 for 30 days, the same for every destination. aloSIM sells data packages measured in GB, bought through its app. If you stream, hotspot-free browse and use maps all day, unlimited removes the math. If you barely use data, a small GB pack can cost less.

Key facts

  • VoaSim charges per day with truly unlimited data — USD 18.90 for 5 days up to USD 106.90 for 60 days, the same price for every destination.
  • aloSIM sells data by GB through its app, which can be cheaper for light users on short trips.
  • VoaSim has no coverage in the island Caribbean; Puerto Rico works on US networks.
  • The Europe plan covers 50 countries with one eSIM, including the UK, Switzerland, Turkey, Norway and Iceland.
  • VoaSim offers human support, an invoice by email, a 100% refund if the eSIM cannot connect, and the free eSIM Rescue tool for any brand.

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 is the same whether you fly to Japan, Portugal or Brazil. Coverage reaches 170 destinations on every continent, and the Europe plan covers 50 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:

Check aloSIM's official site for current packages, validity and tethering rules — those terms change and only the brand itself can confirm them.

VoaSim does not promise tethering: it depends on the plan, so ask support before you rely on it. 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, human support and a guarantee: if the eSIM will not connect and support cannot fix it, you get 100% back.

FAQ

Is VoaSim really unlimited, or is there a fair-use limit?
Truly unlimited: no data cap, no speed throttling and no hidden fair-use clause. You pay for days, not gigabytes. That means you can stream, video call and use maps for the whole trip without checking a usage bar or buying a top-up mid-journey.
Does aloSIM cost less than VoaSim?
It depends entirely on how much data you use. aloSIM sells packages by GB, so a light user on a short trip may pay less. A heavy user who would need several top-ups usually spends less with a flat unlimited day price, which starts at USD 18.90 for 5 days with VoaSim.
Can I keep my phone number with either eSIM?
Yes. Both are data-only eSIMs that sit alongside your physical SIM, so your number stays on the phone and WhatsApp keeps working on it. Just turn off your home carrier's data roaming so you are not billed twice for the same connection.
Does VoaSim work in the Caribbean islands?
Not right now. There is no coverage in the Dominican Republic, Cuba, Jamaica, the Bahamas, Aruba or Curaçao. Puerto Rico does work because it runs on US networks. For those islands, compare aloSIM or another provider before you travel.
When do my VoaSim days start counting?
At the eSIM's first connection to a network at your destination, not when you buy or install it. Install at home on Wi-Fi, keep the eSIM line switched off, and turn it on after you land. Maximum validity is 90 days per eSIM.
Can I use the eSIM as a hotspot?
VoaSim does not promise tethering: it depends on the plan, so contact support before you rely on it. aloSIM describes its own tethering rules in its terms. If sharing data with a laptop or a travel companion is essential, confirm it in writing before you buy.
What if the eSIM will not connect abroad?
Use the free eSIM Rescue tool at voasim.com/sos, which diagnoses a no-signal eSIM of any brand. If it is a VoaSim eSIM and human support cannot get you connected, you get a 100% refund. Support runs by email and on-site chat.
