Lost in Rome No More: How TSIM eSIM App Transformed My Travels
Last updated: October 24, 2026
Planning an international trip involves numerous logistical details, and figuring out how to stay connected online abroad is often one of the most challenging. With so many solutions available, the process can seem overwhelming and expensive.
Thankfully, eSIM technology has emerged as a convenient option, allowing travelers to purchase data plans without dealing with the physical hardware of their phones. I used to rely on some popular brands of global eSIMs for my travels. However, since these services are now banned, I discovered another excellent alternative, which I will review in this article.
TSIM eSIM for Italy: Quick Verdict
| Best for | Short trips to Italy and multi-country Europe trips where you want data the moment you land |
| Setup | Install the eSIM by QR code or in the app before you fly; activate on arrival |
| Network | Uses local Italian partner networks (4G/5G where available) |
| Phone needed | An unlocked, eSIM-compatible phone |
| Price | Varies by data amount and validity – check current TSIM plans before buying |
| Alternative | Local Italian SIM from TIM, Vodafone, WindTre or Iliad – cheaper for long stays but needs ID and a shop visit |
My Previous Experiences with International Data Services
On my first international trip as an adult, I was on a tight budget, viewing data as a luxury rather than a necessity. I opted to turn off my data and rely solely on available WiFi. This strategy worked fine until I found myself lost in Rome, trying to communicate in broken Italian with locals to find my way.
I was supposed to meet a friend, but the inability to contact her only heightened the stress of the situation. Later, I also struggled to find the Colosseum, despite having taken a screenshot of the directions beforehand. Unfortunately, my navigational skills were lacking, and I ended up in an unfamiliar and slightly unnerving part of the city. All of these issues could have been avoided had I researched international data plans and set up a backup option.
After this bad experience, I decided to do my research for my next trip and discovered a reliable eSIM provider. Life became much easier after that, as I started using their eSIMs. They were incredibly convenient and easy to use, and the best part was that they functioned in every country I visited. Travel became significantly more manageable, allowing me to stay connected effortlessly no matter where I went.
But recently, when these popular eSIM brands were banned, I found myself confused and unsure of what to do next. I started looking for other alternatives and discovered TSIM International.
TSIM International: A Game-Changer for Travelers
TSIM International proved to be a fantastic solution. They offer a wide range of international data plans, and their eSIMs are compatible with numerous countries, just like the previous providers I used. The setup process was straightforward, and the customer support was excellent, providing quick assistance whenever I had questions.
Moreover, TSIM has a new app, TSIM eSIM, that has made the experience even more seamless. The app allows you to purchase and manage your eSIMs easily. You can browse different data plans, make purchases directly through the app, and even monitor your data usage in real-time. The user interface is intuitive and user-friendly, making it easy to stay connected no matter where you are.
My Experience Using TSIM eSIMs
Each experience I had with TSIM eSIMs was more effective than any plan I previously had with others. TSIM stands out because it utilizes the local network in each location, rather than relying on the often unreliable international connections provided by other services.
Although physical SIM cards are available, many newer phones no longer support swapping out SIM cards, making eSIMs the only viable option. Conversely, some older phones aren’t compatible with eSIMs.
Guide: How to Use the TSIM eSIM When Traveling
Begin by downloading the TSIM app and creating an account. The app has three simple pages: Plans, My eSIMs, and Profile. In the Plans section, you can purchase local, regional, and global eSIMs. If you’re looking for a specific country, there’s a handy search feature. Once you purchase a plan, it’ll show up in the My eSIMs section.
It’s important to activate your eSIM before you travel. Make sure you have a stable WiFi connection and simply follow the instructions for the download. This varies depending on your phone.
Download Instructions for iPhones
- Note that the eSIM installation process must not be interrupted, and make sure your device has a stable internet connection before installing.
- Tap “Install eSIM,” tap “Continue” twice, and wait for a while. Your eSIM will connect to the network.
- Choose a label for your new eSIM plan.
- Choose “Primary” for your default line, then tap “Continue.”
- Choose the “Primary” you want to use with iMessage and FaceTime for your Apple ID, then tap “Continue.”
- Choose your new eSIM plan for cellular/mobile data, then tap “Continue.”
When you’re ready to activate your eSIM, go into the settings under the Cellular Data section and simply toggle on the eSIM you want to use. It will take a couple of seconds to connect. Make sure to also turn on data roaming.
You can keep your primary line on if you want to keep your number for iMessage, WhatsApp, and FaceTime (recommended). Be sure to never delete your downloaded eSIMs; just toggle them off when you’re done. They automatically get archived in the app when they run out of days.
Within the app, you can check and see the status of your eSIMs and how many gigabytes are left. There, you can top off your data as needed. Packages expire after a certain period, depending on which plan you purchase. Even when the eSIM expires, you can always buy another plan to add more days.
Before you go to a new country, make sure to have the eSIM downloaded ahead of time, so all you have to do is toggle it on.
Cost and Benefits
Most plans do not include a phone plan; they’re data-only. If you have WiFi calling enabled, this is usually not a problem. The only time I encountered an issue with not having a phone plan was when I was trying to make reservations at local restaurants. If this is important to you, consider looking into an additional phone plan. Some countries do not work with TSIM. The global plans are compatible with 124 countries.
eSIM plan prices vary depending on which one you purchase. Different countries have different plan costs. Regional and global are more expensive because they cover wider areas and have the ability to tap into many different networks. A one-gigabyte purchase is around $4.50 for many countries in Europe.
You can store credit cards in the app for easier purchasing. Also, users have the opportunity to earn TSIM points. Depending on the amount you purchase, you get a certain level of cashback. I am currently a platinum traveler and I get 10% cashback. This is a wonderful feature because I have been able to get many free gigabytes of data this way.

Conclusion
Overall, I had great success using TSIM during my three months abroad, and it ended up being far cheaper than using an American international data plan. As a digital nomad, TSIM was a lifesaver while I was working abroad. On trains that didn’t have WiFi, I was still able to work from my hotspot.
Whether you’re traveling to Thailand or the Caribbean, there are options for many destinations around the world that provide flexibility like no other data plan. Plan your next trip knowing that there’s an easy solution for international travel data plans.

RESPONSIBLE TRAVELING-BECAUSE I CARE
FAQs
What are the best attractions in Rome?
This article isn’t a sightseeing guide — it’s about staying connected abroad with eSIM data plans, and uses the author’s experience of getting lost in Rome (trying to communicate in broken Italian while relying only on WiFi) as the story that prompted her switch to eSIM travel data.
Is Rome worth visiting?
The article doesn’t cover this directly since its focus is travel connectivity, but the author’s own Rome story — navigating the city without reliable data and getting lost — reflects a real, memorable (if stressful) part of her travels there.
How much time should I spend in Rome?
The article doesn’t address trip length for Rome; it’s centered on reviewing TSIM International, an eSIM data provider, rather than offering a Rome travel itinerary.
What is Rome famous for?
The article doesn’t detail Rome’s attractions — its content is about international eSIM data plans — but it does reference Rome as the setting for the author’s cautionary tale about traveling without a reliable data connection.
Is Rome tourist-friendly?
The article doesn’t assess this directly, though the author’s account of struggling to communicate in broken Italian while lost, with no data to fall back on, suggests that having reliable connectivity (rather than relying solely on WiFi) makes navigating Rome considerably easier.
I’m planning a trip to Rome — what should I prioritize seeing and doing there?
This particular article won’t help with sightseeing priorities — it’s a review of TSIM International’s eSIM data plans for staying connected abroad — but based on the author’s own Rome experience, prioritizing a reliable data plan before you arrive is one practical takeaway.
Can you give me an honest, first-hand take on what Rome is actually like to visit?
The author’s honest anecdote: on an early international trip, she tried to save money by turning off her data and relying only on WiFi, which worked fine until she got lost in Rome and had to navigate in broken Italian to find her way — an experience that changed how she approaches connectivity on every trip since.
What’s the best time of year to visit Rome, and why?
The article doesn’t address seasonal timing for Rome — its focus is entirely on eSIM data plans for international travel.
What should a first-time visitor to Rome know before they go?
Based on the author’s experience, don’t count on WiFi alone to navigate a new city — she recommends securing a reliable eSIM data plan before travel, since her own attempt to go data-free in Rome left her lost and struggling to communicate.
How does Rome compare to nearby destinations for someone deciding where to go?
The article doesn’t compare Rome to other destinations — it’s a review of an eSIM data provider (TSIM International) that the author says works reliably across many countries, including wherever her travels, Rome included, have taken her.
Is an eSIM better than a local SIM in Italy?
For short trips, an eSIM is more convenient because it works on arrival without a shop visit or ID. For longer stays with heavy data use, a local Italian SIM is usually cheaper.
Does TSIM work in Rome?
Yes. TSIM connects to local partner networks in Italy, and I used it in Rome for maps, ride-hailing and messaging.
Do I get an Italian phone number with a travel eSIM?
Most travel eSIM plans are data-only, so you won’t get an Italian number. You can still use WhatsApp and internet calling.
How do I install an eSIM before travelling to Italy?
Buy the plan, scan the QR code or install it from the app over Wi-Fi at home, then switch your mobile data to the eSIM and enable roaming when you land.
