Straight answer: Truphone is an eSIM brand that sells travel data as prepaid allowances by country or region, managed in its app or website. VoaSim works differently: one truly unlimited data eSIM, one price per duration for all 170 destinations — 5 days USD 18.90, 7 days USD 23.90, 15 days USD 42.90, 30 days USD 61.90 — paid in USD by card, with human support and a refund guarantee.

Key facts

  • Truphone-style eSIMs sell data by allowance and country; VoaSim sells truly unlimited data at one price per duration.
  • VoaSim pricing: USD 18.90 for 5 days up to USD 106.90 for 60 days, the same for all 170 destinations.
  • Validity starts at the first connection abroad, so install at home and keep the eSIM line off until you land.
  • A GB-based plan may cost less for very light users on a short single-country trip — that is a fair reason to pick it.
  • No coverage in the island Caribbean right now; Puerto Rico works on US networks, and cruises only work at port.

If you searched for "Truphone eSIM", you probably want to know whether a data-allowance eSIM is the right way to stay online abroad. This page explains the model in plain terms and compares it fairly with the unlimited approach VoaSim sells.

This is a comparison of models, not a lab test. Prices, plan sizes and terms change often, so always confirm current details on each provider's official site or app before you buy.

How the Truphone eSIM model works

Truphone sits in the group of eSIM brands that sell travel data as a prepaid allowance. In practice, that usually means you pick a destination or region, pick a data size, pick a validity window, and get a QR code by email or inside the app.

The model has a clear logic: you pay for what you expect to use. It also has a clear risk: if you underestimate, you run out mid-trip and have to top up, often at a moment when you have no connection to buy anything.

A few things to verify on the official site before buying any allowance-based eSIM:

Our general guide to travel eSIMs is at /esim/.

Allowance by GB vs truly unlimited: the real difference

The decision is mostly about how you use your phone on a trip. Data by GB rewards light users: email, messaging, a few maps. Unlimited rewards everyone else — video calls home, Google Maps running all day, uploading photos, streaming in the hotel, hotspot-free tethering aside.

VoaSim sells a single product: a travel eSIM with truly unlimited data. No cap, no throttling, no hidden fair-use clause buried in the terms. You never check a data counter and you never top up mid-trip.

The trade-off is honest: if your whole trip is three days of light messaging, an allowance plan may cost less. If you have no idea how much data you will burn, or if you are traveling with someone who watches Netflix on the train, unlimited removes the guessing. See how we compare other brands at /compare/.

VoaSim price table: one price per duration

VoaSim charges the same price for every one of its 170 destinations. The country does not change the price; only the number of days does. Today's promo price (15% off) looks like this:

DurationPrice (USD)Per day
5 days18.903.78
7 days23.903.41
10 days30.903.09
15 days42.902.86
30 days61.902.06
60 days106.901.78

Trips of 1 to 4 days pay the 5-day package. Maximum is 90 days per eSIM. A second eSIM in the same order gets 10% extra off — useful for couples. The lowest daily rate is USD 1.78/day on the 60-day plan. Get your exact figure at the price simulator.

Coverage, payment and delivery, without surprises

VoaSim covers 170 destinations on every continent, including Brazil, connecting automatically to local networks on 4G and, where available, 5G. The Europe plan covers 50 countries with a single eSIM, including Switzerland, the UK, Turkey, Norway and Iceland — details at /esim/europe/.

One honest gap: there is no coverage right now in the island Caribbean — Dominican Republic, Cuba, Jamaica, Bahamas, Aruba, Curaçao. Puerto Rico works, because it runs on US networks. On cruises, the eSIM works on land at ports, not at sea.

Payment is by international credit or debit card in USD through Stripe, with no hidden fees and an invoice sent by email. No cash, no local-currency billing. The QR code arrives by email within minutes, with a WhatsApp heads-up if you left a number. Install before you fly using our iPhone and Android guides at /guides/.

Compatibility and when days start counting

Your phone needs eSIM support: iPhone XR or newer, Samsung Galaxy S20 or newer, Google Pixel 3 or newer, and most phones released from 2020 on. The universal check is to dial *#06# — if an EID appears, the phone supports eSIM. Carrier-locked phones must be unlocked first. VoaSim does not sell physical SIM cards.

Validity starts at the eSIM's first connection to a network at your destination, not at purchase. So install at home and leave 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 phone number keep working, so WhatsApp stays on your usual number. Just switch off data roaming on your home carrier. VoaSim is data-only: no phone number and no traditional voice calls, but WhatsApp calls, app calls and maps all work over data. On hotspot, do not assume it: it depends on the plan, so confirm with support first.

When Truphone (or another option) is the better pick

We would rather be useful than pushy. Choose an allowance-based eSIM like Truphone, or a GB-based brand such as Airalo, Nomad or Ubigi, if you are a genuinely light user, if you want to buy a small package for a single country, or if you need a specific feature VoaSim does not sell, like a local phone number.

A local physical SIM can still win when you need a local number for deliveries or bank codes — accepting the shop visit, passport registration and taking your own SIM out of the phone. Carrier roaming (T-Mobile, AT&T, Verizon, EE, Vodafone, Google Fi and others) is the simplest option if your plan already bundles it; check the current rate in your carrier app, since terms vary by country.

Choose VoaSim if you want unlimited data with no counter, a single price per duration, human support, a 100% refund if the eSIM cannot connect and we cannot fix it, and the free eSIM Rescue tool for any brand with no signal.

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 Truphone an eSIM I can use as a tourist?
Truphone is one of several travel eSIM brands that sell data as prepaid allowances by country or region, delivered as a QR code. Whether it suits your trip depends on the current plan sizes, validity rules and coverage. Check those on Truphone's official site before buying, since terms change.
How is VoaSim different from a Truphone-style plan?
VoaSim sells one thing: truly unlimited data with no cap and no throttling, at one price per duration for all 170 destinations. Allowance-based plans charge by GB and by country, which can be cheaper for light use but requires you to estimate your consumption in advance.
How much does a VoaSim eSIM cost?
With today's 15% promo: USD 18.90 for 5 days, USD 23.90 for 7, USD 30.90 for 10, USD 42.90 for 15, USD 61.90 for 30 and USD 106.90 for 60 days. Same price for every destination. Trips of 1 to 4 days pay the 5-day package.
When do my days start counting?
Days begin at the eSIM's first connection to a network at your destination, not when you buy or install it. Install at home, keep the eSIM line off until you land, and on Android avoid switching on the eSIM's data before the trip.
Does my phone number stop working?
No. Your physical SIM and your number stay active, so WhatsApp keeps working on your usual number. VoaSim is data-only, with no number and no traditional voice calls. Just turn off data roaming on your home carrier so you are not billed for it.
What if the eSIM will not connect?
Contact human support at hola@voasim.com or through the on-site chat. You can also run the free eSIM Rescue tool at voasim.com/sos/, which diagnoses an eSIM of any brand with no signal. If support cannot fix it, you get a 100% refund.
Does the eSIM work on a cruise?
It works on land, at the ports you visit, as long as the destination is in our coverage list. It does not work at sea, where only the ship's satellite service is available. Note there is currently no coverage in the island Caribbean, though Puerto Rico works.
