iD Mobile is available to UK-based customers who want to use their mobile plan abroad in supported countries. It lets you use your UK plan’s calls, texts, and data in 50 destinations, making it useful for staying connected while traveling without buying a local SIM card.
iD Mobile roaming is best for UK holidaymakers and business travelers who want the convenience of keeping their existing plan active while abroad.
It offers solid value if your trips stay within the 50 Roam Free destinations, though the 30 GB cap may be limiting for very heavy data users.
iD Mobile’s eSIM is a digital SIM that replaces the need for a physical card while giving you the same features included in your plan. It can be activated by scanning a QR code sent by email, through the iD Mobile app, or by entering details manually in your phone settings.
The service runs on the Three network in the UK, with access to 4G and 5G where available, and includes roaming in 50 Roam Free destinations where you can use your UK allowances up to the 30 GB fair use cap.
To use it, your device must be unlocked and eSIM compatible. You can also switch from a physical SIM to an eSIM in the iD Mobile app or your online account, and if you transfer to another device you simply generate a new QR code.
iD Mobile roaming makes it easy for UK customers to use their plan abroad without extra charges. Here are the main reasons to consider the service, along with its key limitations:
Benefits:
Limitations:
For iD Mobile, roaming is included on all SIM-only plans, which can also be activated as an eSIM.
These plans are the most flexible option for UK customers who want to use their allowances abroad without being tied to a handset contract.
Below are the recommended deals currently highlighted on iD Mobile’s website, though many more data options are available.
| Data Allowance | Price (per month) |
| 50 GB | £10 |
| 120 GB | £6 (half price for 3 months, £12 thereafter) |
| Unlimited | £8 (half price for 6 months, £16 thereafter) |
All plans include unlimited UK minutes and texts and come with free roaming in 50 destinations, subject to a 30 GB fair use cap.
iD Mobile includes a Roam Free feature on all SIM-only and phone plans, allowing UK customers to use their data, calls, and texts abroad. Here is what you need to know about where and how it works:
In the UK, iD Mobile operates on the Three UK network, giving customers access to its 4G and 5G coverage.
When traveling abroad, iD Mobile connects to partner networks in 50 Roam Free destinations and in other supported countries outside this zone.
The availability of services such as 5G depends on the local networks in each country.
Speeds and reliability vary because they are determined by the infrastructure of these partner providers, and iD Mobile does not publish specific data on roaming performance.
At home, customers are tied to Three’s network, and abroad connections are automatically managed through roaming agreements rather than user choice.
iD Mobile includes its Roam Free feature on all SIM-only and phone plans, giving UK customers the ability to use their plan abroad without extra costs. Here is what the roaming service offers:
On Trustpilot, iD Mobile holds an overall rating of around 4 stars, reflecting a mix of positive and negative feedback. Since roaming is a standard part of all iD Mobile plans, these reviews provide insight into the overall service experience that also affects roaming users.
Some customers report weak coverage, with one noting “extremely poor signal even in central London” compared to other networks. Others describe reception as “reasonable” in both the UK and EU, suggesting performance can vary by location.
Customers who rated the service positively highlight the value of low-cost SIM-only plans and the stability of fixed prices on long-term deals. No major issues with eSIM or SIM setup were mentioned in the sampled reviews.
Support is the most common complaint. One reviewer said there is no phone number for customer service and that live chat is unreliable, leaving issues unresolved. This suggests support responsiveness is an area where iD Mobile underperforms compared to competitors.
Overall, iD Mobile is praised for affordability and simple roaming inclusion but criticized for inconsistent coverage and limited support options.
For budget-conscious UK travelers who want roaming in 50 destinations, it remains a strong value option, though service quality may feel less reliable than larger carriers.
iD Mobile offers customer support primarily through live chat on its website and app, as well as a community forum where staff and other users provide guidance.
There is no dedicated phone number for general customer service, which many reviewers note as a drawback. Email support is limited, with most queries directed through chat or the community.
In terms of responsiveness, live chat can resolve straightforward issues like billing or plan changes, but customers often report difficulty reaching an agent quickly or getting complex problems resolved.
The community forum provides useful resources, though it is not always a substitute for direct help.
The iD Mobile app is available on both iOS and Android and serves as the main hub for managing your plan.
Users can check data, minutes, and text usage in real time, view and pay bills, set spending caps, and buy add-ons such as extra data if needed.
The app also supports switching from a physical SIM to an eSIM, with activation handled by scanning a QR code or following the on-screen setup.
From a user experience perspective, the app is designed to be straightforward and minimal. It avoids clutter by focusing on the essentials, making it easy for customers to manage their accounts without needing to contact support.
While iD Mobile includes roaming in 50 destinations for UK customers, international travelers often compare it with global eSIM providers because these services are available worldwide, work regardless of your home country, and usually cover more destinations than iD’s Roam Free.
Here are some of the top alternatives:
| Provider | Strengths | Best for | |
| Holafly | Unlimited data plans with 24/7 support | Heavy users abroad who want worry-free usage | |
| Nomad | Budget-friendly pricing and regional plans | Occasional travelers who only need light data | |
| GigSky | Wide international partnerships, flexible data packs | Frequent flyers who visit multiple regions | |
| Yesim | Simple app-based setup, pay-as-you-go style | Travelers who prefer on-demand data without commitments | |
For UK-based customers, iD Mobile roaming is the simplest choice since it is already built into every plan and allows you to use your UK allowance abroad with no extra steps.
But if you are traveling outside the 50 Roam Free destinations or need more than the 30 GB fair use limit, Holafly is often the better option. It offers unlimited data in far more countries, making it especially valuable for long-haul trips and heavy data users.
Compared with Nomad, GigSky, and Yesim, Holafly is stronger because it removes the need to monitor data usage, provides wider coverage, and includes round-the-clock support, while the others either limit you to smaller data packs, charge higher rates per gigabyte, or only focus on specific regions.
Yes, iD Mobile includes free roaming in 50 destinations with your UK allowances, subject to a 30 GB fair use cap.
Yes, iD Mobile offers Roam Beyond add-ons for destinations outside the 50 Roam Free countries.
It is a feature that lets UK customers use their plan’s data, calls, and texts abroad in 50 supported destinations.
iD Mobile keeps costs low by being a digital-first network with fewer overheads and by using Three’s existing infrastructure.
