Top 5 best eSIM for study abroad
At Travel ESIM Expert we know about studying abroad, Estefania, our co-founder, left home to study in Paris and London. It’s an exciting experience, but one that comes with a lot of life administration. Sorting out a phone plan is one thing that will probably be high on your to do list.
We are always transparent here at Travel ESIM Expert, and from our experience, getting a local SIM will usually be the cheapest option for getting online overseas in the long run. However, depending on the country you’re moving to, that can come with a ton of issues such as:
- Complex registration rules: Some countries require proof of residence, student visa paperwork or even a local ID before you can sign up.
- Long wait times / admin delays: It can take weeks or months to get everything sorted. In Estefania’s case: 4 months due to bank account and local number requirements.
- Language barriers: Plans, contracts, and sign up processes are in the local language, which can be confusing and easy to choose the wrong option.
- Inflexible contracts: Many providers only offer 12-24 month contracts, which are not super student friendly. Prepaid SIMs might exist but we’ve had issues in the past – it’s one of the main reasons we loved that eSIMs came along.
- Limited coverage / poor value for short stays: Local SIMs are optimised for residents, not temporary visitors. You might end up overpaying or locked into more data than you need.
- Upfront costs: Sometimes you need to pay activation fees, buy the SIM in person, or top up with large amounts at once.
That’s where eSIMs make life much easier. Instead of worrying about spending weeks for approval or heading to physical stores, you’ll be able to get online from the moment you arrive in your destination.
Convenience aside, the benefits are huge for students: lower costs compared with roaming, flexibility for weekend trips to other countries and the ability to keep your home SIM active for banking codes, etc.
How to choose the best eSIM for your study abroad trip
Not all eSIMs are created equal thanks to a ton of variables. The “best” one for a student studying in Tokyo will be completely different from the best one for a student studying throughout Europe. Instead of just picking the cheapest option, you’ll need to match a plan to your specific needs. By considering the 5 factors below, you’ll have a much better idea of what eSIM is best for you.
1. Coverage: One country or the whole continent?
The first and most important question to ask is: where will you be using your phone? eSIM providers typically offer two types of plans:
- Single country plans: These plans work in one specific country (e.g., a “Spain only” plan). They are usually the cheapest option if you know you’ll be staying in one place for the majority of your time.
- Regional Plans: These cover an entire region under a single plan (e.g. “Europe,” “Asia,” or “North America”).
The type of plan you want is really going to depend on what you get up to on the weekends. Heading to Europe and wanting to see different countries during your time studying there? A regional plan would make sense and save you time. If you don’t plan to travel reqularly, you could stick with a single country plan for your main destination. The key thing to consider is that the regional plans, will cost more, so be sure to consider how regularly you’ll actually be traveling. If you do go for a regional plan, the convenience would be unmatched.

If you’re not planning on traveling regularly, we would recommend sticking with a single country plan and then looking into both types of plans on an ad-hoc basis.
2. Data: How many Gigabytes (GB) do you actually need?
Data amount is an important, but difficult one to get to grips with. While you’ll very likely have WiFi at home or in some public spaces, mobile data is so essential when navigating, translating and more in a new country.
The best way to figure out how much data you’ll require is to use our handy Data Calculator. However, here’s a short form version of how we think it breaks down.
The light user (5-10 GB/month):
- You’re almost always on Wi-Fi
- You just need data for essentials like Google Maps, WhatsApp messages and looking up bus schedules when you’re out
The average user (15-30 GB/month): The sweet spot for most students, covering:
- Daily navigation
- Frequent social media use (scrolling Instagram, TikTok, etc.)
- Streaming music on your commute to class
The Heavy User (50 GB – Unlimited/month): You use your phone for everything…
- Tethering your laptop at a café
- Constantly streaming video lectures, or uploading high resolution content for your blog or social media, etc.
When we travel, we tend to slightly overestimate the amount of data we require. Why? The cost per GB of data reduces signfiicantly with the more GB you purchase. If you need to buy a little more data at any point thanks to a top up, it’s going to cost you much more per GB. On the flip side, if you do not use the full amount of data purchased, you haven’t maximized your value, the effective cost per GB increases.
Knowing the amount of data you require will only really come with time and experience of your usage habits.
3. Validity: Matching your plan to your time overseas
The validity of your plan is the number of days your plan will remain active. Different eSIM providers will offer a broad range of validity periods, with many topping out at 30 day as standard, so it’s important to keep a close eye on it when purchasing your eSIM.
- For a short summer program, a 30 day plan is perfect and convenient.
- For a full semester (typically 3-4 months), a 90-day or 180-day plan is ideal.
The ideal scenario would be an eSIM that:
- Lasts for the duration of your program
- Provides enough data for your requirements
This means you should be able to make your purchase and “Set and forget” it, without the need to regularly purchase additional plans. That’s the theory anyway, in practice, plans lasting longer than 30 days can sometimes be tricky to find. That’s why we’ve outlined our pick of the bunch below.
4. Features: Do you need a phone number for calls and texts?
Important: The majority of eSIMs are data only. This means that you get mobile data to get yourself online, but not a local phone number for making voice calls or sending SMS text messages.
This should suffice 90% of the time for activities such as using iMessage, WhatsApp, Facetime, Messenger, etc. However, a local number can be useful in certain scenarios, such as:
- Making appointments
- Using local services
- Receiving SMS confirmations
There are various ways around this if you think you’ll need a local number.
- Some eSIMs do come with local numbers
- There are apps available that enable you to obtain a local number
- You could get a cheap Pay As You Go local SIM – very easy in some countries like the UK, very difficult in countries with bureaucracy at every turn.
5. Price: Finding the best value per Gigabyte ($/GB)
The cheapest priced plan isn’t always the best deal. To accurately compare eSIMs, you need to calculate the price per GB. The formula is simple:
Total cost ÷ Total Gigabytes = Cost per GB
For example: A $40 plan with 30GB of data ($1.33/GB) vs $25 plan with 10GB of data ($2.50/GB)
In this instance, the $40 plan of course costs more, but you are getting a lot more data for your money. As we discussed earlier however, make sure you use that data to get the $1.33 price. Unused data increases the effective cost per GB.
Take ten seconds to do this quick math before you buy; it ensures you’re getting the most data for your money.

Final thoughts: Picking the right eSIM for studying abroad
Studying abroad is an exciting and rewarding experience, but it also comes with headaches. Sorting out a phone plan doesn’t have to be one these days. While local SIMs can sometimes be cheaper in the long run, the reality is that for many, they involve paperwork, bureaucracy, waiting, contracts and confusion. eSIMs cut that hassle out and solve each issue, offering instant connectivity, flexible plan lengths and the ability to travel.
The “best” eSIM will always depend on your situation based on factors unique to you:
- Where you’re studying
- How long you’re staying
- How much you travel
- How much data you actually use
A semester in one country might only need a single country plan, while a year abroad with weekend trips makes a regional or flexible option far more appealing.
Our advice is to weigh up our 5 key factors:
- Coverage
- Data
- Validity
- Phone numbers
- Price
Then pick the plan that matches your lifestyle, not just the cheapest number on the page. Whether you choose RedteaGo for all-round ease and value, Roamless for flexibility, Maya Mobile for long term validity, or SIM Local for calls and SMS, an eSIM will give you one less thing to worry about while settling into your new life overseas.
FAQ
1. Can I just get one eSIM for my whole semester abroad?
Yes, absolutely. You will be able to top-up almost any eSIM, but for even more convenience, choose a plan with longer validity. For a short summer program, a 30-day plan is fine. For a semester, a 90- or 180-day plan is ideal so you can “set and forget” without constant top-ups. A full academic year usually means renewing once or twice. Providers like Maya Mobile even offer 180-day plans worldwide, which is why they’re so useful for long term students.
2. Do I really need a local SIM if I have an eSIM?
Usually not. With an eSIM you’ll have instant data and can keep your home SIM in for banking codes or 2-factor authentication. The only exception to that rule is in countries with strict bureaucracy (looking at you France), where you might need a local number to open a bank account or sign certain contracts. In those cases, you can either pick an eSIM that includes a number (e.g. SIM Local) or grab a cheap pay-as-you-go SIM once you’re set up.
3. What happens if I run out of data mid-month?
You can top up instantly through most eSIM apps, but the catch is that topping up a smaller amount is usually more expensive per GB. That’s why we always suggest slightly overestimating how much data you’ll need.
4. Do eSIMs come with a phone number?
The majority of eSIMs don’t, they’re either data-only or allow you to make internet (VOIP) calls. That’s fine for calling others or the usual: WhatsApp, iMessage, FaceTime and Zoom, which all run over data. But if you need to make appointments, receive SMS confirmations, or use services that require a local number, SIM Local is the best option we’ve tested. Their plans include calls and SMS with local numbers in destinations like France, the UK, and the USA.
5. Isn’t campus Wi-Fi enough? Do I even need mobile data?
Campus Wi-Fi is great when you’re on site, but you’ll need mobile data for maps, transport apps, keeping in touch on the go, and especially for weekend travel. Having both gives you peace of mind.
6. What’s the best eSIM for studying abroad in Europe?
For Europe, regional eSIMs are usually the most convenient choice. They let you travel freely between countries without switching plans. Students spending a semester in one country may prefer a single country eSIM for lower costs, but if you plan to explore on weekends, a Europe wide plan will save you time, money and hassle.
