The best eSIM for a round the world trip is rarely a single plan. For most long trips, a long-validity global eSIM covers the travel days and border crossings, while cheaper local or regional eSIMs take over in the countries where you stay for weeks. If you want one line and no planning, a monthly global subscription is the simpler option, at the cost of a minimum term.
Key takeaways
- A long term travel eSIM needs two things a holiday plan lacks: long validity and a way to add data without starting over.
- Saily and Nomad Global-EX list packages valid for up to 365 days; Saily's 20 GB for 365 days is listed at $66.99.
- Ubigi and Holafly sell monthly global plans. Ubigi's 20 GB World plan is $44 a month and can be cancelled only after 3 months.
- Mixing global and local eSIMs usually gives the best balance of coverage and cost on a route with long stops.
- Travel eSIMs are usually data only, so keep your home SIM active for bank codes and calls.
One plan or many: how to think about a long route
A round the world itinerary mixes two kinds of days. Some are transit days, when you cross a border, land in a third country before lunch and need data the moment the plane touches down. Others are slow days, when you stay put for a month and use far more data.
A global eSIM is built for the first kind of day. One profile works across many countries, so you never land without a connection. Local eSIMs suit the second kind of day, because single-country plans are usually cheaper per gigabyte than multi-region ones.
The price gap is real. A BytesIM comparison published in April 2026 put a typical 10 GB, 30-day plan at about $15-25 for Europe and $12-22 for Asia, against about $35-60 for a global multi-region plan.
Simplest
One long-validity global plan
Buy a large global package once and top up when it runs low. Best when you move fast and rarely stay longer than a week or two.
Predictable
A monthly global subscription
Pay a fixed amount each month for a set allowance or unlimited data. Best for a digital nomad eSIM setup where work depends on staying online.
Cheapest per GB
Global base plus local plans
Keep a small global plan for transit days and buy local eSIMs for long stops. Best for slow travel and heavy data use.

Long-validity plans: what is on offer in 2026
A 365 day eSIM sounds like the obvious answer for a year away, but the details matter. Validity, data allowance and country list differ a lot between providers, as the table shows.
| Provider | Long-trip option | Listed coverage | Listed price | Phone number |
|---|---|---|---|---|
| Saily | Global packages up to 365 days: 10 GB/180 days, 20 GB/365 days, 50 GB/365 days | 121 destinations | $56.99, $66.99, $129.99 | Optional US number, ID check |
| Nomad | Global-EX: 10-50 GB, valid 10-365 days | 98 destinations | From $2.58/GB | Not listed |
| Airalo | Global packages with top-up and auto-renew at 10% remaining; unlimited up to 30 days | 168 countries and networks | From $8.50; unlimited 30 days $159 | Some packages include calls and texts |
| Holafly | Month-to-month unlimited global plan | More than 160 countries | Not listed in our sources | No |
| Ubigi | World 20 GB per month, auto-renewed, cancel after 3 months | 200+ destinations | $44 per month | Data only |
| TonMobile | Local, regional and global plans; top-ups on the same eSIM | 180+ countries | Shown live in the app | Data only |
Validity versus data
Long validity does not mean a lot of data. Saily's 20 GB package lasts 365 days, which is generous on time and modest on volume for anyone who streams or works online. Treat it as a safety net and plan extra data for heavy months.
Coverage gaps
Nomad lists 123 destinations for its Global plan but 98 for Global-EX, the line with long validity. Saily's Global plan lists 121. Before you buy, check every country on your route against the provider's list, not only the headline number. Our methodology page explains how we read these coverage claims.
Global eSIM subscriptions for nomads
A global eSIM subscription renews every month, so you never have to remember to buy the next package. That suits remote workers who cannot afford a gap in service between two countries. The trade-off is a commitment and, in some cases, rules on where you can use it.
Pros
- Ubigi's World plan renews automatically and lists 200+ destinations, among the widest lists in this guide.
- Ubigi allows data sharing and recharging in the app without Wi-Fi.
- Holafly's month-to-month plan removes the data cap, which helps heavy users.
Cons
- Ubigi's 20 GB monthly plan can be cancelled only after 3 months.
- Ubigi cannot be used by Canadian residents in Canada or UAE residents in the UAE.
- Holafly limits hotspot sharing to 1 GB per day on its global plans, and a fair usage policy can slow speed for up to a day.
Holafly's hotspot cap matters if you plan to tether a laptop. A subscription with a fixed allowance and data sharing, like Ubigi's, can suit laptop work better than an unlimited plan with a sharing limit.
Watch the minimum term
Ubigi lists its 20 GB World plan as auto-renewed with cancellation possible after 3 months. If your trip is shorter than that, a long-validity package or pay-as-you-go top-ups will likely cost less.
Mixing global and local eSIMs
Mixing global and local eSIM plans is the setup most long-term travelers end up with. The global line stays on the phone as a backup and for transit days, and each long stop gets its own local or regional eSIM.
Local eSIM
One country
Regional eSIM
One region, many countries
Global eSIM
Many regions on one profile
Carrier roaming
Whatever your home plan covers
Buying everything from one provider makes this easier. TonMobile sells local, regional and global packages for more than 180 countries in one app, so the global backup and the local plan for a month in Turkey or the UAE sit in the same account. Its release notes also list buying several eSIMs at once and tracking remaining data and validity, which helps when you hold more than one line.
Roaming from home is the fallback most travelers want to avoid. AT&T International Day Pass and Verizon TravelPass are both listed at $10 per day, which comes to $140 for two weeks.
How to build a mixed setup
Map your stops by length
List each country and how long you will stay. Stops of a week or less go on the global line; longer stops get a local or regional plan.
Install the global eSIM at home
A travel eSIM can be installed before you fly, while your home SIM stays in the phone. Install the global line on home Wi-Fi so it is ready on day one.
Buy local plans a few days ahead
Before each long stop, buy and install the local eSIM while you still have a connection. Turn its data on when you land.
Top up instead of reinstalling
When a plan runs low, add data to the same eSIM if your provider allows it. TonMobile and Airalo both list top-ups, so you keep one profile per line.
Payment is the other part of a long trip that changes. If a card gets blocked abroad, a provider that takes several payment methods saves the day. Our guide to paying for an eSIM with crypto covers that option.
Managing several eSIMs on one phone
An eSIM is a SIM profile downloaded onto a chip built into the phone, so several profiles can sit on one device without any plastic cards. A clear system stops you paying for data on the wrong line.
- Label each line by country and provider, for example "Global backup" and "Thailand local".
- Set the active local eSIM as the data line and keep the home SIM for calls and SMS.
- Turn off data roaming on the home SIM so it never takes over by mistake.
- Note each plan's expiry date in your calendar.
- Keep the QR codes or install links until each plan has expired.
Keep your home number active. Travel eSIMs from TonMobile, Ubigi and Holafly are data only, so bank codes still arrive on the home SIM. If you need a number abroad, read our guide to travel eSIMs with a phone number and SMS.
Use the bonus before it expires
Some providers pay cashback you can spend on the next plan. TonMobile's web app credits cashback, referral and promotion bonuses to a USD balance that expires after 1 year and cannot be withdrawn, which fits a year-long trip if you spend it as you go.
When a line stops working after a border crossing, our guide to fixing an eSIM that is not working abroad walks through the checks. Terms such as eUICC, ICCID and fair usage policy are explained in the glossary.
FAQ
What is the best eSIM for a round the world trip?
For most long routes, the best setup is a long-validity global eSIM for transit days plus local eSIMs for stops of several weeks. Travelers who move fast may prefer one global plan, and remote workers may prefer a monthly subscription.
Is there a 365 day eSIM for long-term travel?
Yes. Saily lists global packages of 20 GB and 50 GB valid for 365 days, at $66.99 and $129.99, covering 121 destinations. Nomad's Global-EX line lists validity from 10 to 365 days across 98 destinations.
Is a global eSIM subscription worth it for a digital nomad?
A subscription suits nomads who need data every month without planning. Ubigi's World plan gives 20 GB per month for $44 across 200+ destinations, but it can be cancelled only after 3 months.
Can I use a global and a local eSIM on the same phone?
Yes. A phone can store several eSIM profiles, and you choose which one carries data. Many travelers keep a global line as a backup and switch data to a local eSIM during long stops.
Can I top up a travel eSIM instead of buying a new one?
Many providers allow it. Airalo lists top-ups and auto-renew at 10% remaining, Ubigi allows recharging in its app without Wi-Fi, and TonMobile users report topping up without reinstalling the eSIM.
Will I keep my phone number on a long trip with a travel eSIM?
Yes, if you keep your home SIM active alongside the eSIM. Most travel eSIMs, including TonMobile, Ubigi and Holafly, are data only, so calls and bank SMS still come to your home number.
