The Travel eSIM Efficiency Penalty

Speedtest information reveals the hidden wholesale networks and web exit factors behind greater than 50 journey eSIM manufacturers, and the way these selections form latency and pace.

Travel eSIMs have turn out to be the default approach thousands and thousands of vacationers join wirelessly overseas, but nearly nothing about how they work is seen to the folks shopping for them. Two vacationers standing on the identical road, linked to the identical native community, can expertise response occasions that differ by an element of ten due to selections made in wholesale agreements they don’t seem to be conscious of.

Speedtest® information from Q2 2026 lets us open that black field at scale. Because our information captures the SIM profile on the machine, the visited community, and the purpose the place visitors reaches the general public web, we will map each main journey eSIM model to the wholesale community that anchors it, hint the place on this planet its visitors surfaces, and quantify precisely what that routing structure delivers when it comes to latency, pace, and total expertise.

Key Takeaways:

• Travel eSIMs are taking share of worldwide roaming, not simply using a busier journey 12 months. Measured exercise from branded journey eSIMs grew at a powerful double-digit charge within the twelve months to June 2026, considerably outpacing the 12% development in complete worldwide roaming exercise and lifting journey eSIMs from 2.7% to three.4% of all measured roaming. Because this share measure is impartial of how many individuals traveled, it factors to a real shift in traveler conduct.
• A handful of wholesale networks underpin a lot of the market. More than 50 retail manufacturers depend on a concentrated pool of suppliers that orchestrate roaming agreements all over the world. Those suppliers are Hutchison’s networks in Austria and Hong Kong, China Mobile Hong Kong, KPN, Orange, Singtel, Telna, Webbing, Transatel, Proximus, BICS, Plus in Poland, and Sky within the UK. Brand loyalty doesn’t exist at this layer, with a number of manufacturers switching wholesale suppliers throughout the quarter.
• Where an eSIM exits to the web can matter as a lot because the native cellular community. Under dwelling routing, visitors is shipped again by the supplier’s core community, typically out of the country, earlier than reaching the web. Some manufacturers use a single hub, akin to Madrid, London, or Singapore, whereas others unfold visitors throughout a number of regional hubs. True native breakout, the place visitors exits within the nation being visited, stays unusual. On the identical Japanese community, median latency ranged from 54 ms with native routing to 543 ms when visitors was despatched by Madrid, regardless of similar radio situations.
• Commercial coverage is seen in efficiency, not simply routing. Download pace distributions reveal caps and throttled plans, with one main model clustering close to 6 Mbps and a free tier close to 0.2 Mbps. In the worst model and vacation spot pairings, latency was as much as 30 occasions larger than for native cellular customers on the identical community.

A market coming of age, and a provide chain nonetheless within the shadows

The industrial momentum behind journey eSIMs is now not in query. Airalo grew to become the section’s first unicorn in July 2025 on the again of a $220 million spherical, and the corporate says it serves greater than 20 million vacationers. Holafly, its closest rival, says it has crossed $500 million in cumulative income. The addressable base retains widening as Apple ships eSIM-only iPhones in a rising record of markets and distant SIM provisioning turns into routine throughout the machine base. Distribution is broadening in parallel, from journey platforms embedding connectivity within the reserving move to fintech apps like Revolut promoting information packs beside forex alternate.

Operators have observed. In the U.S., T-Mobile now sells its personal prepaid travel eSIM for inbound guests, Nord Security’s (recognized for its fashionable NordVPN) Saily has scaled from a standing begin into one of many section’s bigger manufacturers, and several other nationwide operators quietly white-label wholesale journey eSIM platforms beneath their very own logos.

At the identical time, the infrastructure behind the class has attracted tutorial scrutiny. A USENIX Security research final 12 months mapped two dozen manufacturers’ egress factors from a single US vantage level, and a peer-reviewed measurement paper introduced at ACM IMC unpicked one model’s roaming structure throughout 24 nations, discovering that its eSIMs by no means used true native breakout (the place visitors connects to the web inside the nation being visited).

Those research established the high-level state of play however couldn’t observe the market at scale, constantly, from actual customers. This is the hole our evaluation closes. We recognized the branded journey eSIM footprint in Speedtest information for Q2 2026 throughout roughly 190 vacation spot nations, attributed every model to the wholesale networks that its profiles are primarily based on, verified each egress location towards public interconnection information and latency outcomes, and benchmarked every model towards native customers in the identical nations, and the place doable on the exact same host networks.

Under the model label sits a wholesale id that almost all vacationers are unaware of

Every eSIM profile carries two identities. The label on the machine usually reveals the retail model (like Airalo or Holafly). The SIM’s dwelling community code (the id it makes use of to authenticate and roam) belongs to the underlying wholesale community, and that community is registered within the ITU’s E.212 register (whether or not or not the association is publicly revealed). Reading and correlating each layers directly, as we now have performed right here, makes the retail market clear.

The wholesale layer, performing like a donor, is strikingly concentrated. For instance, Hutchison’s Austrian community underpins roughly two thirds of Holafly’s measured samples in our information. China Mobile Hong Kong anchors the remaining third, together with CMLink’s personal retail base and several other smaller manufacturers.

KPN within the Netherlands is Airalo’s largest wholesale anchor, accounting for greater than a 3rd of its samples in our information. Airalo additionally makes use of Webbing’s Hong Kong vary, Orange France, Play in Poland, and Telna’s US vary. Singtel helps Nomad, Eskimo, and Asian journey platform Trip.com’s eSIM, whereas Proximus and BICS help Roamless and Firsty. Sky UK anchors the multi-brand eSIM Go platform, Transatel (an NTT firm) helps Ubigi by its world 901 vary, and Vodafone UK powers Revolut’s in-app eSIM.

Two vital observations spotlight how commercially fluid this layer is. First, a number of manufacturers run multi-donor estates with a number of wholesale companions and seem to steer clients between them by vacation spot, so the identical journey eSIM model sells a Hutchison-anchored profile for one journey and a China Mobile-anchored one for the subsequent. Second, we discovered operator manufacturers themselves showing as tenants on wholesale ranges, with profiles broadcasting main European and Middle Eastern operator names on Telna’s US community code, proof that some operators have chosen to purchase fairly than construct their journey eSIM functionality.

Every eSIM has an exit door, and it’s often situated far-off

Under the GSMA roaming mannequin that underpins these merchandise, information not often reaches the web the place the traveler truly stands. It is tunneled to a packet gateway operated by the SIM’s dwelling community or its cloud accomplice, and solely there does it floor.

Our information reveals the place these exits are situated, as a result of the community that arms every check to the web is seen within the measurement itself, and the Speedtest server the app selects reveals the place the connection topologically lives. We verified the ensuing map 3 ways, towards the interconnection amenities every community lists publicly, towards latency outcomes, and towards the place displaced server alternatives land, with all three agreeing.

At a excessive stage, our information reveals three architectures rising:

Single hub designs backhaul every little thing to 1 metropolis. Holafly’s Hutchison Austria property exits overwhelmingly in Spain, on infrastructure whose interconnection footprint sits fully in and round Madrid. The result’s a model whose world median multi-server latency was 320 ms in Q2. Yesim exits in London and Warsaw. Roamic exits in London. Eskimo exits in Singapore. eSIM Go’s property exits in London. CMLink exits in Singapore for a lot of the world, with a separate Frankfurt exit serving European locations, a regionalization that retains its European latency respectable whereas leaving American customers of its Hong Kong-anchored profiles with a 17x latency a number of.

Distributed cores route visitors by a number of exit places. Saily makes use of its personal registered community and exits in Germany, the Netherlands, the US, Singapore, and Japan, producing a world median multi-server latency of 117 ms. 1GLOBAL additionally controls its personal web routing and exits by the US and 4 European hubs, with a median latency of 121 ms. Webbing had essentially the most domestically routed community we measured. Its ten amenities, spanning Tokyo to Dallas, saved practically three quarters of visitors within the nation the place the check occurred. Airalo sits between the 2 fashions, routing visitors by Vienna, Amsterdam, London, the US, and Singapore, reflecting its use of a number of wholesale suppliers.

Local breakout stays the exception. Airalo’s Japan-specific profiles floor visitors in Japan and delivered a 54 ms median on the au community, inside 1.5x of native customers. Almost nothing else we measured does this, which means the trade default stays a tunnel to some other place (which simplifies setup and reduces prices considerably).

Google Fi, a U.S.-based full MVNO with world roaming included, serves as a superb comparator towards devoted journey eSIM manufacturers. Its visitors exits within the U.S. and can be funneled by a London cloud core (relying on buyer location). Traveling subscribers on Google Fi recorded a 335 ms median latency, slower than most devoted journey manufacturers. This reinforces the case that distance to the visitors exit, not merely the model, units the latency flooring.

Routing selections drive extreme latency penalties on journey eSIMs

Benchmarked towards native customers in the identical vacation spot and quarter, the median multi-server latency a number of throughout studied journey eSIM model and vacation spot pairs runs from 1.5x to 30x. The worst pairings are all single-hub manufacturers measured removed from their routing hub.

For instance, Amsterdam-routed profiles in Australia reached 30x native latency. Madrid-routed profiles reached 25x in Singapore, 18x in Thailand, and 15x in Japan. Singapore-routed profiles reached 17x within the United States. These are clearly not native radio results formed by the visited community. On Japan’s au community, the place native customers recorded a median of 36 ms, the unfold of latency throughout manufacturers on similar underlying radio infrastructure ran from 54 ms to 543 ms relying solely on the place every model’s tunnel surfaces.

Speedtest picks the bottom latency server obtainable, and for hub-routed eSIMs, that server is continuously out of the country, as a result of by the tunnel it genuinely is nearer. Two in 5 assessments on the most important hub-routed manufacturers chosen a server outdoors the vacation spot nation.

Samples in Thailand on Amsterdam-routed profiles landed on Dutch servers greater than 9,000 km away at a 434 ms median multi-server latency. Samples within the U.S. on Madrid-routed profiles, in the meantime, landed on Spanish servers at 361 ms. Samples in China on foreign-anchored profiles landed in Hong Kong, Taiwan, Singapore, and Vietnam.

These elaborate routing patterns additionally clarify why many journey eSIM profiles behave, for content material localization functions, as if the consumer have been outdoors the nation. Wherever the exit sits, that’s the place the web thinks a consumer is (except GPS or location companies can be found to calibrate additional), a mechanism distributors of geolocated companies document explicitly.

Responsiveness beneath load, captured by our loaded latency metric, paints a equally stark image. Median loaded latency exceeded 1.2 seconds on Holafly’s Madrid hub, 1GLOBAL’s London multi-brand platform, and the carrier-wrapped manufacturers, and sat close to 900 ms even on well-engineered distributed cores. The lengthy tunnels noticed with these options add queueing on high of distance, which means the manufacturers with the longest paths additionally confirmed the biggest inflation between idle and dealing latency (contributing to poorer high quality of expertise in functions like video conferencing and gaming).

Speed is a pricing determination, with laborious caps artificially limiting efficiency

Throughput variations on journey eSIMs typically mirror industrial coverage greater than underlying community high quality. Several manufacturers cluster round slender obtain pace medians with little variation, indicating deliberate pace caps fairly than variable radio situations.

Yesim’s world median obtain pace of 6.03 Mbps and Instabridge’s 10.23 Mbps level to throttled limitless plans. Firsty’s free tier was deliberately restricted to 0.21 Mbps. Airalo reached a world median of 30.11 Mbps, however repeated plateaus close to 20 Mbps throughout a number of Asian markets recommend profile-level pace caps in its wholesale agreements or tariff design.

At the opposite finish, 1GLOBAL (80.21 Mbps), Nomad (80.26 Mbps), and Ubigi (75.89 Mbps) ship obtain pace medians that method native norms, and Holafly’s 56.87 Mbps reveals {that a} hub structure can nonetheless transfer bulk information rapidly even whereas including a 3rd of a second to each spherical journey when it comes to latency. In essence, pace and latency have decoupled with journey eSIMs, and clients are selecting between them with out figuring out it.

Similarly, 5G entry seems to be formed extra by industrial agreements than technical limits. Most main manufacturers now hook up with 5G in at the very least half of their samples in our information in Q2, led by Ubigi at 62%. Others stay largely 4G-based, with 5G shares of simply 20% to 36%, suggesting that wholesale 5G entry has not been secured in each market, particularly for smaller gamers.

The provide chain is in fixed movement, and efficiency strikes with it

The wholesale market underpinning the journey eSIM manufacturers is consistently shifting. Our information reveals a number of main provider adjustments within the 12 months to June 2026. Airalo roughly doubled the share of its samples anchored on KPN, whereas reducing Orange France by half and onboarding Telna, whose share jumped inside a single month. Holafly consolidated round its Hutchison Austria wholesale anchor whereas showing to part its Orange France profiles out fully.

Saily, which entered the market on rented wholesale anchors, stood up its personal registered community in late 2025 and now runs 95% of its measured samples by its personal distributed core, a transfer that coincided with the strongest latency profile among the many giant manufacturers in our information.

These wholesale shifts can have a speedy impression. Brand-level median efficiency was in any other case extremely steady throughout the 2 halves of our research. However, the model that modified wholesale suppliers most extensively minimize its world median latency by about 100 ms between April and June as new community companions carried extra of its visitors.

What this implies for the trade

Travel eSIM manufacturers are already carrying a significant and fast-growing share of inbound customer visitors on cellular operators’ radio networks whereas anchoring the shopper relationship, and the billing relationship, elsewhere. Our measurements present the place there’s weak point within the merchandise operators provide. A visited community operator or nationwide operator group that gives wholesale native breakout, or sells its personal customer eSIM with genuinely native egress, will beat most of this market on responsiveness by an order of magnitude.

For wholesale enablers and journey eSIM manufacturers, structure is now measurable competitors. Distributed cores and regional exits visibly outperform single hubs on each responsiveness metric, and types that run their very own networks management their very own future in a approach tenants don’t. As the class consolidates and matures, the hole between a 100 ms product and a 500 ms product shall be more and more laborious to cover behind a headline worth per gigabyte.

For vacationers, the sensible steering is easy even when the underlying wholesale provide chain just isn’t. The finest journey eSIM for a given journey is the one whose exit door is closest to the vacation spot.

Methodology

Our evaluation covers Q2 2026 Speedtest information on Android units, the place SIM-level attributes allow model identification, throughout roughly 190 vacation spot nations, with a 24-month collection for market evolution.

Travel eSIM classes are recognized from the SIM profile’s service supplier identify and residential community code, certified as worldwide roaming, and validated as mobile for the total period of every check. VPN-flagged assessments are excluded.
