VoaSim vs Nomad: truly unlimited vs by-GB

VoaSim team · Updated 2026-09-25
Traveler comparing eSIM plans on a phone at an airport gate, VoaSim vs Nomad unlimited versus by-GB data
Straight answer: VoaSim and Nomad are both travel eSIMs, but they sell data differently. Nomad sells packages measured in GB through its app, so you pick a data amount and a validity window. VoaSim sells truly unlimited data by duration, one price for every destination: USD 18.90 for 5 days, USD 61.90 for 30 days, USD 106.90 for 60 days.

Key facts

  • Nomad sells data by the gigabyte through its app; VoaSim sells truly unlimited data by the day.
  • VoaSim charges one price for every destination: USD 18.90 for 5 days up to USD 106.90 for 60 days (USD 1.78/day).
  • A small GB package can be cheaper for a light-use short trip; unlimited wins for streaming, maps and remote work.
  • VoaSim has no coverage in the island Caribbean, so choose another brand for Cuba, Jamaica or the Bahamas.
  • Install the QR before you fly: days start counting at the first connection at the destination.

This is a comparison of two business models, not a lab speed test. Nomad is a well-known eSIM brand that sells data packages by GB, mostly through its app. VoaSim sells travel eSIMs with truly unlimited data, priced by the number of days you travel, with the same price for every destination.

Below you get how each model works, the VoaSim price table, a side-by-side checklist and an honest note on when Nomad is the better pick for you.

How each model works

Nomad (an eSIM brand available in local, regional and global flavors) sells data in gigabytes. You choose a destination, a GB amount and a validity period in its app. If you finish the GB before the trip ends, you buy a top-up. Check the exact caps, validity and tethering rules in Nomad's own terms and app, since they change by plan and country.

VoaSim removes the GB math. You buy days, not gigabytes: no data cap, no speed throttling, no hidden fair-use clause. The same price applies whether you fly to Japan, Brazil, Mexico or Portugal. Coverage reaches 170 destinations on every continent, and the Europe plan covers 50 countries with a single eSIM, including Switzerland, the UK, Turkey, Norway and Iceland.

Both are data-only products. You keep your own number and WhatsApp on your physical SIM; calls and maps run over data. Neither gives you a local phone number.

When Nomad is the better pick

Being fair matters more than winning the argument. A by-GB eSIM can be the smarter buy when:

VoaSim wins when you stream, upload video, use maps all day, work remotely or travel as a family and do not want anyone rationing data. Unlimited also removes the worst travel surprise: running dry in a taxi line at 11 pm.

Setup, activation and support

After checkout the QR code lands in your email within minutes, plus a WhatsApp heads-up if you left a number. Install it before you fly, following the step-by-step guide for iPhone and Android.

Your days start counting at the eSIM's first connection to a network at the destination, not at purchase. So install at home and keep the eSIM line switched off until you land — on Android, do not turn on the eSIM's data before the trip. Your physical SIM and your number keep working; just turn off your home carrier's data roaming.

Compatibility: iPhone XR or newer, Samsung Galaxy S20 or newer, Google Pixel 3 or newer, and most phones released from 2020 on. Dial *#06#: if an EID appears, your phone supports eSIM. Carrier-locked phones must be unlocked first. VoaSim does not sell physical SIM cards.

Stuck with no signal — on any brand? The free eSIM Rescue tool runs a diagnosis. Human support answers at hola@voasim.com and on chat.

What neither eSIM does

Both are data-only. No traditional voice line, no SMS number of your own. WhatsApp, Telegram, FaceTime and app calls work fine over data, on your existing number.

Cruises: a travel eSIM connects on land at ports, not at sea. Onboard satellite Wi-Fi is a separate purchase from the cruise line.

Hotspot and tethering: do not build your trip around it. With VoaSim it depends on the plan — ask support before you rely on it. With Nomad, read the plan terms in the app.

Also worth comparing against your own carrier's roaming pass before you decide. Daily passes from T-Mobile, AT&T, Verizon, EE, Vodafone or Telstra can be convenient for a weekend, but they usually bill per day of use with a daily data allowance and reduced speeds afterwards, and often need enabling before departure. Rates change by country — check the current one in your carrier app, and see our roaming guide.

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's unlimited data really unlimited?
Yes. There is no data cap, no speed throttling after a threshold and no hidden fair-use clause. You buy days, not gigabytes. The eSIM connects automatically to local networks on 4G and, where available, 5G, across 170 destinations including Brazil.
Which is cheaper, VoaSim or Nomad?
It depends on how much data you use. A small GB package can be cheaper for a light-use short trip. For heavy use, maps all day, streaming or remote work, VoaSim's flat price wins: USD 18.90 for 5 days down to USD 1.78 a day on the 60-day plan.
Do I lose my phone number if I use VoaSim?
No. VoaSim is a data-only eSIM that sits alongside your physical SIM. Your number and WhatsApp stay active on your usual line. Just switch off your home carrier's data roaming so you do not get billed twice.
When do the VoaSim days start counting?
At the eSIM's first connection to a network at the destination, not at purchase. Install the QR code at home before flying and keep the eSIM line off until you land. On Android, do not enable the eSIM's data before the trip.
Can I use VoaSim as a hotspot for my laptop?
Do not count on it without checking. Hotspot availability depends on the plan, so confirm with support before you rely on tethering for work. The same applies to other brands: read the tethering rules in their terms.
What if the eSIM does not connect at my destination?
Contact support first at hola@voasim.com or via on-site chat, and run the free eSIM Rescue tool at voasim.com/sos, which diagnoses eSIMs of any brand. If support cannot fix it, you get a 100% refund.
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, look at a by-GB eSIM brand instead.
