Market sizing for eSIM is unusually messy, and the mess matters if you are making an investment decision. Different research houses count different things, publish figures with different denominators, and have revised their own forecasts substantially in the last two years. Quoting a headline number without knowing what it measures is how business plans end up built on the wrong assumption.
This is a consolidated view of where the market actually stands going into the second half of 2026: what the credible forecasts say through 2030, where they disagree and why, how the different measures relate to each other, and how to use any of it in a plan.
The short version
- eSIM smartphone penetration was roughly 5% at the end of 2025 and is forecast to reach 10% by the end of 2026.
- 2030 forecasts range from 55% to 82% of smartphones, so the direction is settled and the pace is not.
- Read the denominator before the number: 42% and 55% can both be right for 2030.
- Travel is where the consumer revenue is, at roughly $5 billion in 2026.
- Device availability stopped being the bottleneck; awareness and distribution are the constraints now.
Where the market stands in 2026
The defining shift happened suddenly rather than gradually. Two events in late 2025 changed the arithmetic: Apple extended its eSIM-only iPhone design beyond the United States into global markets, and Chinese operators launched smartphone eSIM services for the first time, opening a market previously restricted to wearables and IoT modules.
GSMA Intelligence put global eSIM smartphone penetration at roughly 5% at the end of 2025, forecast to reach around 10% by the end of 2026 and to double again during 2027. Penetration was approximately 3% in 2024, with nearly half of that concentrated in the United States.

Why the 2030 forecasts disagree
The direction is not in dispute. The pace is. Published 2030 estimates for eSIM share of smartphones range from 55% to 82%, a spread wide enough to describe two quite different markets.
2030 eSIM smartphone penetration: how the forecasts diverge
Sources: GSMA Intelligence; ABI Research; Counterpoint Research. Each house\'s published 2030 estimate for eSIM share of smartphones, shown as published rather than averaged.
The gap comes down to assumptions about mid-range devices. Counterpoint’s higher figure assumes manufacturers remove physical SIM trays quickly across the mid and budget tiers. ABI’s more conservative view notes that as of 2025, over 70% of smartphones in circulation still lacked eSIM support at all, and replacement cycles take years to work through. GSMA Intelligence sits between them.
The five measures, and what each is for
Most disagreement between published figures dissolves once you know which measure is being used.
| Measure | What it counts | Use it for | Do not use it for |
|---|---|---|---|
| eSIM-capable devices | Handsets that could take a profile | Sizing the technical addressable market | Estimating demand; capability is not usage |
| Devices actively using an eSIM | Profiles in live use | Understanding real adoption | Revenue projections; many are operator profiles, not travel plans |
| eSIM share of smartphones | Percentage of smartphone connections | Comparing regions and tracking the transition | Comparing against "share of all SIMs" figures |
| eSIM share of all SIM technologies | Includes feature phones and IoT modules | Understanding the whole connectivity market | Anything smartphone-specific |
| Travel eSIM retail spend | Consumer money spent on travel plans | Sizing the revenue pool you can address | Enterprise or IoT opportunity, which it excludes |
What each research house actually publishes
Side by side, with definitions attached.
| Research house | What they measure | Headline figure | Why it differs |
|---|---|---|---|
| GSMA Intelligence | eSIM smartphone connections | 4.9 billion by 2030, about 55% of smartphone connections | Revised down from an earlier 6.7 billion estimate after adoption ran slower through 2024 |
| GSMA Mobile Economy 2026 | eSIM share of all SIM technologies | 2.5 billion connections by 2028; 42% of SIM technologies by 2030 | Denominator includes feature phones and IoT, so the percentage is lower |
| ABI Research | eSIM smartphone penetration | 57.7% by 2030 | Notes over 70% of smartphones still lacked eSIM support as of 2025 |
| Counterpoint Research | eSIM smartphone penetration | 82% by 2030 | Assumes faster removal of SIM trays across mid-range devices |
| Juniper Research | Devices actively using an eSIM | 1.2 billion in 2025 rising to 1.5 billion in 2026 | Counts devices using a profile rather than devices capable of one |
| Kaleido Intelligence | Travel eSIM retail spend | $3.3 billion in 2025, approaching $5 billion in 2026, close to $10 billion by 2028 | Measures consumer spending on travel plans, not connection counts |
Figures as published by each house. Where estimates conflict they are shown side by side rather than averaged, because the underlying definitions differ.
Device availability is no longer the constraint
For most of the last decade the honest answer to slow eSIM adoption was that not enough devices supported it. That has largely cleared.
Cumulative eSIM-capable device models announced

The supply of compatible hardware is now growing faster than consumer awareness of what to do with it. That inversion matters commercially: the bottleneck has moved from manufacturing to distribution and education, which is precisely the part of the chain a reseller or travel brand can address.
Regional adoption is highly uneven
Global averages hide differences of several years between regions. If you are choosing where to sell, the regional picture matters far more than the global one.
Ahead of the curve
- North America expected past 50% smartphone adoption by 2027
- The United States shows the highest consumer penetration of any single market
- China entered the smartphone eSIM market in late 2025 and is expected to become the largest by volume
- South Korea shows unusually high consumer awareness
Following behind
- Europe not expected past 50% until around 2029
- Regional roaming pricing reduces the immediate saving on intra-regional trips
- Markets with strong prepaid physical SIM retail convert more slowly
- Regions dominated by mid-range handsets wait on eSIM below the flagship tier

Uneven adoption is not automatically a reason to chase the most mature markets. High-penetration markets carry the most competition and the most price pressure. Markets in the middle of their adoption curve, where devices support eSIM but awareness is still forming, often offer better economics for a new entrant with a specific angle.
Where the consumer revenue actually is
Connection forecasts describe the long-term size of the category. Travel eSIM describes the part already generating consumer revenue at scale.
Global travel eSIM retail spend
Source: Kaleido Intelligence. By 2028 travel eSIM is forecast to represent over 80% of all travel SIM spend and around 28% of total travel connectivity spend.
Kaleido Intelligence tracked travel eSIM retail spend at $3.3 billion in 2025 and expects it to approach $5 billion in 2026, reaching close to $10 billion by 2028, at which point it is forecast to account for over 80% of all travel SIM spend.
Two behavioural signals inside that growth matter more than the headline. Average spend per trip rose 133% year on year to around $28 in 2026, while roaming spend per trip fell 9% to around $42, and 15% of travel eSIM buyers now choose unlimited plans. Meanwhile Opensignal measured travel eSIM users rising from 1.7% to 3.3% of its global user base between Q2 2025 and Q2 2026, with roaming losing 5.2 percentage points of share. The category is taking revenue directly from operator roaming.
How to use these figures in a business plan
Market forecasts are useful for orientation and dangerous as plan inputs. Six rules make them usable.
Pick the measure that matches your business
If you sell travel plans, travel eSIM retail spend is your revenue pool. Connection forecasts describe the long-term size of the category and will overstate what you can address today by a wide margin.
Discount the forecast, not the direction
GSMA Intelligence revised its own 2030 estimate from 6.7 billion connections down to 4.9 billion. Forecasts in this category have moved before and will again. Build your plan on the current trajectory rather than the most optimistic published figure.
Apply regional reality to your target markets
Global averages hide a two-year gap between North America and Europe, and larger gaps elsewhere. The number that matters is adoption in the specific markets you intend to sell into.
Convert market size into addressable audience
A $10 billion category by 2028 is not your addressable market. Narrow it to your corridor or segment, then to the share you could realistically reach, before it means anything for planning.
Model on current behaviour, not projected behaviour
Travel eSIM reached a small single-digit percentage of travellers in 2026. Plans that assume 2030 adoption rates in 2027 fail in the intervening years regardless of whether the forecast eventually proves right.
Re-check the figures annually
The numbers in this category move materially year to year, in both directions. A business case built on 2024 figures was working from a forecast that has since been revised down substantially.
Step five is where most plans in this category go wrong. A forecast that eSIM reaches 55% of smartphones by 2030 says nothing about how many customers you can acquire in 2027. Travel eSIM reached only 3.3% of measured travellers in mid-2026, and a plan that assumes end-state adoption arriving early will run out of money before the market catches up, even if the forecast eventually proves correct.
