Best eSIMs Inside Super Apps (2026): Revolut, N26, Viber and More Compared

You no longer need a dedicated eSIM app to buy travel data. A growing list of mainstream apps now sell eSIM data plans from inside the app you already use for banking, messaging or booking trips. Revolut and N26 sell in-app travel data powered by telecoms firm 1GLOBAL, Rakuten Viber switched on a built-in eSIM store on 17 July 2026, and platforms such as Trip.com, Klook and Booking.com resell travel eSIMs alongside hotels and tours.

The appeal is obvious: no new account, no new payment details, and one less app on your phone. The catch is that super apps are generalists. Coverage lists are shorter than the 200+ destinations offered by Airalo or Nomad, unlimited plans are often missing, and prices range from genuinely cheap (Revolut's promotional 1 GB plans) to unremarkable.

This guide covers every super-app eSIM we could verify as live in July 2026, flags the rumoured offerings we could not confirm, and compares real prices against specialist providers so you can see exactly what the convenience costs. Our assessment criteria are consistent across eSIMVerdict: price, coverage, network quality, plan flexibility, transparency, ease of use, hotspot support and customer service.

Banking apps: Revolut and N26

Revolut eSIM: the benchmark super-app offering

Revolut launched eSIM data plans in February 2024, making it the first UK financial institution to do so. The service is provided by 1GLOBAL, with Revolut acting as agent, and covers just over 100 countries and territories. Independent reviews put the exact figure at 108 as of May 2026.

Pricing is more competitive than you might expect from a bank. Revolut's USA eSIM page advertises plans from £1.50 for 1 GB over 7 days, while the general data-plans page quotes top-ups "from just £3.49 for 1 GB". A review by Locals Insider (May 2026) recorded in-app prices of £1.50 for a short 1 GB plan and £7 to £18 for 30-day plans of 3 GB to 10 GB. Plan sizes run from 1 GB up to 100 GB over 60 days. Two details stand out: using the Revolut app itself does not consume your eSIM data allowance, and RevPoints can be redeemed against data plans from 100 points.

The subscription tie-in is Ultra, Revolut's top tier at £55/month, which includes 3 GB of global data every month. That only makes sense if you already want Ultra for other reasons; no other tier gets free data or a checkout discount.

Limitations are real. Plans are data only, there is no unlimited option (10 GB is the largest standard plan size in many markets), coverage trails the 200+ destinations of Airalo and Nomad, and you must hold a Revolut account to buy anything. Revolut also does not publish a full price list on the open web, which we consider a transparency weakness; you see final prices only in the app. For a sense of how specialist coverage compares, see our Airalo review.

N26 Travel eSIM: the same engine in a German wrapper

N26 added a Travel eSIM to its app through the same partner, 1GLOBAL, announced in May 2025 and since promoted across its European markets. The travel product covers over 100 countries with prepaid, data-only plans bought from the "More" menu in the N26 app; your main number stays active for calls and texts on your physical SIM. 1GLOBAL's partnership announcement also references full mobile plans with voice, SMS and 5G in some markets, but the travel eSIM sold in-app is a data product.

N26 does not publish prices on its website either, and we found no eSIM-specific discount for Go or Metal subscribers as of 18 July 2026. The proposition is essentially Revolut's, minus the included-data tier. It is convenient for existing N26 customers and unremarkable for everyone else.

Messaging apps: Viber becomes an eSIM seller

Rakuten Viber launched a built-in eSIM service on 17 July 2026, the day before this article was checked, running on Rakuten Mobile's cloud eSIM platform. Users buy plans for over 150 countries from the "More" menu, pay by card, Apple Pay or Google Pay, and activate automatically on landing. Plans must be activated within 90 days of purchase, and Android users can top up an existing eSIM for the same country without reinstalling.

The plans are data only and include no local number, which matters less inside Viber: the company points out that Viber calls and messages work over the eSIM data. Viber does not publish a price list on its help pages, so we cannot yet judge value against specialists; treat it as a convenience play until independent pricing data emerges. It is nonetheless a significant launch, because Viber's user base is largest in markets such as Eastern Europe, the Balkans and the Philippines where eSIM adoption is still growing.

We found no equivalent WhatsApp offering. Despite persistent speculation, our research found no official WhatsApp or Meta eSIM product or partnership as of 18 July 2026; the many "WhatsApp eSIM" articles online are guides to using WhatsApp over ordinary travel eSIMs.

Fintech's other route: Klarna Mobile is not a travel eSIM

Klarna entered mobile in 2025, but in a different direction. Klarna Mobile, built on the Gigs platform, is a full US phone plan: $35/month ($30 for Klarna Max members) for unlimited 5G data, talk and text with priority access on AT&T's network, 10 GB of hotspot data, and eSIM activation through the Klarna app. Roaming covers Mexico and Canada with unlimited data plus 1,000 minutes and texts; beyond North America there is currently no coverage. Klarna's June 2025 announcement (at an initial $40 price) promised international and premium plans "later this year", and UK and Germany launches; as of 18 July 2026 we could verify only the US plan. If you want travel data for a fortnight in Europe, Klarna Mobile is not the product.

Travel platforms: resellers, not operators

Trip.com sells eSIMs and physical SIMs through its store with pre-departure activation and refunds available before the eSIM is installed. Klook lists dozens of eSIM products delivered as QR-code vouchers, including plans running on Softbank and DOCOMO in Japan, SKT in South Korea and the Verizon network in the USA. Both are marketplaces: the underlying provider varies by listing, so support quality, top-up rules and refund terms vary too, much as they do on MobiMatter.

Booking.com's eSIM presence is a co-branded storefront at booking.breezesim.com, run by Breeze eSIM, covering 190+ countries with 7-day plans advertised from £4.00 for the USA. You buy from Breeze, not Booking.com, and the advertised headline prices reflect promotional structures, so read the allowance details carefully. Marketplace listings can be excellent value, but the extra layer between you and the network is exactly the kind of variable we track in eSIM reliability guide.

Promotions that come and go: Grab, Uber and Skyscanner

Three widely reported "super-app eSIMs" are really partner promotions rather than in-app products. Grab ran a giveaway of 1 GB of global data across 145+ countries through roaming provider KnowRoaming, reported in July 2025 and redeemed by voucher code in the Grab app. Uber offered Uber One members a free 250 MB travel eSIM through ConnectedYou, but that promotion expired on 1 July 2025; a 2023 report of code for in-app eSIM purchases in Uber's Android app has never become a shipped feature we could verify. Skyscanner published a sponsored partnership with Nomad in May 2026 with a 20% discount code, but purchases happen on Nomad's site, not inside Skyscanner.

We could not confirm any eSIM offering from Bolt, PayPal or Venmo as of 18 July 2026. Note that "Bolt eSIM" and "eSIM Bolt" storefronts found online are unrelated eSIM retailers trading under a similar name, not products of the ride-hailing company.

The adjacent trend: VPN brands selling eSIMs

The super-app story is part of a wider pattern of non-telecom brands selling connectivity. Saily, from the NordVPN team, covers a long list of destinations with USA plans at $3.99 for 1 GB (7 days) up to $36.99 for 20 GB, unlimited plans from $48.99 with 5 GB/day at full speed then up to 1 Mbps, unlimited hotspot use, and security extras such as virtual location and ad blocking. It holds a 4.7/5 Trustpilot rating. Holiday.com, from the ExpressVPN team but sold without any VPN, covers 150+ destinations from $3.50, with unlimited plans giving 3 GB/day at high speed then unlimited 10 Mbps, one reusable eSIM across trips, and 24/7 live chat. Both undercut most bank-app pricing while offering features, such as unlimited tiers, that super apps currently lack.

So are super-app eSIMs marked up?

Less than you might assume, at least at Revolut. For a 1 GB USA plan on 18 July 2026: Revolut advertised from £1.50 (roughly $2), Nomad from about $3.50, Holiday.com from $3.50, Saily $3.99 and Airalo from $4.00. On that headline comparison Revolut is the cheapest, though the £1.50 price is a short-validity promotional plan and standard top-ups from £3.49 (about $4.50) land level with, or slightly above, the specialists.

The gap appears at larger sizes and in flexibility. Revolut's 30-day mid-size plans at £7 to £18 for 3 GB to 10 GB (about $9.50 to $24.50) compare with Saily's $8.99 for 3 GB and $22.99 for 10 GB: broadly similar, with no consistent super-app premium. What you give up instead is choice. No super app we reviewed offers unlimited plans, voice add-ons or 200+ destination coverage, and none publishes full prices on the open web. Specialists also compete harder on regional multi-country plans; if your trip spans several countries, see multi-destination eSIM guide before defaulting to your banking app.

Advantages and disadvantages

Advantages of buying eSIM data in a super app

• No new account, identity check or saved card; purchase takes a few taps
• Payment in your existing app currency, sometimes with loyalty points (Revolut accepts RevPoints)
• Competitive headline prices for small plans; Revolut's promotional 1 GB plans undercut specialists
• Data usage tracking and top-ups sit in an app you already check
• Included data on premium tiers (Revolut Ultra's 3 GB/month) can make marginal trips free
• Any of these beats paying legacy roaming rates, as our eSIM vs roaming guide comparison shows

Disadvantages

• Coverage of 100 to 150 countries versus 200+ at Airalo and Nomad
• No unlimited plans at Revolut, N26 or Viber as of July 2026
• Prices hidden inside the app; hard to comparison-shop before committing
• Data only; no local number, and voice or SMS needs your primary SIM or an app
• You must hold (or open) the underlying account to buy at all
• Marketplace resellers (Klook, Trip.com, Booking.com/Breeze) add a support layer between you and the network

Who should choose what

• Existing Revolut users on short trips: use Revolut. Small-plan pricing is genuinely competitive and top-ups are frictionless.
• Revolut Ultra subscribers: the included 3 GB/month covers light usage on most trips at no extra cost.
• N26 customers in the EU: the Travel eSIM is convenient, but compare the in-app price against Saily or Airalo before paying; the app shows the price before purchase.
• Viber users in its core markets: promising, but wait for independent pricing evidence or compare in-app prices carefully at checkout.
• Heavy data users and hotspot-dependent travellers: go specialist. Unlimited tiers at Saily, Holiday.com or Holafly do not exist inside super apps.
• Travellers to less common destinations: specialists win on coverage; a 100-country list misses more of Africa, the Pacific and Central Asia than a 200-destination list does.
• Bargain hunters: compare per-gigabyte cost, not headline price; our budget eSIM guide guide shows how quickly "from" prices diverge from real ones.
• US residents wanting one bill: Klarna Mobile is a domestic phone plan with North America roaming, not a travel eSIM; judge it as an MVNO.

The verdict

Super-app eSIMs have moved from gimmick to genuinely usable in two years, and the best of them, Revolut, now prices small data plans at or below specialist level while removing sign-up friction entirely. For an existing user taking a week's trip to a mainstream destination, buying data inside Revolut, N26 or (pricing permitting) Viber is a perfectly rational choice, and vastly better than default roaming.

But convenience currently buys you a narrower product: roughly half the destination coverage of the leading specialists, no unlimited plans, no voice options, and opaque in-app pricing that resists comparison shopping. Frequent travellers, heavy users and anyone heading beyond the top 100 destinations will still do better with a dedicated provider, whether a veteran such as Airalo or Nomad or a newer non-telecom brand such as Saily or Holiday.com. Our advice: keep a specialist app for serious trips, and treat your super app's eSIM as the handy fallback it is, checking the in-app price against a specialist's public price list, which takes under a minute, before you tap buy.

Frequently asked questions

Which super apps actually sell eSIMs in 2026?

Verified as of 18 July 2026: Revolut and N26 (both powered by 1GLOBAL), Rakuten Viber (launched 17 July 2026 on Rakuten Mobile's platform), and resale storefronts from Trip.com, Klook and Booking.com (via Breeze eSIM). Klarna sells a full US phone plan rather than a travel eSIM. We could not confirm offerings from Bolt, PayPal, Venmo, WhatsApp or Uber.

Is Revolut's eSIM cheaper than Airalo?

Sometimes. Revolut's promotional 1 GB USA plan from £1.50 undercuts Airalo's $4.00 equivalent, and its 30-day mid-size plans are broadly in line with specialist pricing. Airalo counters with roughly double the destination coverage, unlimited options in select markets and public price lists. Compare in-app before buying.

Do super-app eSIMs include calls and texts?

No. Revolut, N26's travel product and Viber's eSIMs are data only. Your existing number keeps working for calls and SMS via your physical SIM or primary eSIM, and app-based calls (including Viber and WhatsApp) run over the data plan. Klarna Mobile is the exception because it is a full domestic phone plan.

Who provides the network behind these eSIMs?

Revolut and N26 plans are provided by 1GLOBAL, a telecoms company that acts as the actual service provider. Viber's service runs on Rakuten Mobile's cloud eSIM platform. Booking.com's storefront is operated by Breeze eSIM, and Klook and Trip.com resell plans from various operators and aggregators. In every case your data travels over local partner networks at the destination.

Do I need to keep the super app installed while travelling?

Yes, for buying and topping up, since plans are managed in-app. Once installed, the eSIM itself works at system level, so data flows even if the app is closed. Revolut states that using its own app does not count against your data allowance.
