From eSIMs to offline maps and data-saving modes — quickly, conveniently and without surprises.
Introduction: where do unnecessary travel costs come from?
When we set off, the internet becomes the “oxygen” for navigation, bookings, remote work and keeping in touch with loved ones. Unfortunately, bills can rise surprisingly quickly: after exceeding roaming limits, through uncontrolled app updates, automatic cloud backups or sharing internet with a laptop. The good news is that many of these costs can be predicted — and actively limited.
Instead of relying on expensive roaming or looking for physical SIM cards in each new country, more and more travellers are using eSIM solutions. This is a virtual profile that you activate in a minute, without replacing a plastic card, with packages tailored to the region and length of the trip. If you value simplicity and want clear costs, check out the eSIM app — it lets you activate a data package in a few steps before departure or already at the airport, and then conveniently top it up.
Below you will find five practical tricks that will genuinely reduce your travel internet budget — without sacrificing comfort and with an emphasis on data security.
Trick 1: Choose an eSIM instead of roaming — activation in just a few minutes
Why it works:
Roaming can still come with surprising extra charges — especially outside the EU or after reaching FUP limits. An eSIM provides predictable costs: you buy a package (e.g. a regional European or global one), install the profile and immediately know how much data you have available. Importantly, an eSIM works alongside your physical card — you do not lose your number while using local or regional internet.
Quick start step by step:
- Install the eSIM app.
- Choose the country/region and a data package suited to the length of your trip.
- Install the eSIM profile according to the instructions in the app.
- Turn on mobile data and use the internet without unexpected costs.
Money-saving tip:
New users can use the code YESIMULMNE10 — it gives 10% off to start. It is worth entering it with your first package purchase, especially before a longer trip.
When it pays off most:
- trips through several countries (frequent border crossings),
- remote work while travelling (video conferences, CRMs),
- short city breaks, when quick activation without searching for a SIM card shop matters.
Trick 2: Offline maps and “offline-first” — have internet when you really need it
Why it works:
Navigation can consume a lot of data, especially when refreshing maps and traffic information. The solution is “offline-first”: download map areas in advance, then mainly use GPS while travelling, which does not need the internet.
How to do it in practice (example):
- Before departure, download maps for the region/country you are visiting.
- Save key routes and points (accommodation, stations, attractions) in bookmarks.
- Set travel apps to “Wi-Fi only” mode for synchronising photos and videos.
- Make your phone ask for permission before downloading large files over mobile data.
Additional benefit:
Offline also means greater security. Public Wi-Fi at airports and cafés can be unstable and is not always safe — by limiting its use, you minimise the risk.
Trick 3: Data-saving mode + smart app settings
Why it works:
The system and apps often update “in the background”, send photos and videos to the cloud, and stream in high quality. This is convenient, but while travelling it means unnecessary GB.
What to enable:
- Data-saving mode in the system (Android/iOS) to limit background transfers.
- Lower video quality on streaming platforms and messengers.
- Autoplay disabled on social media.
- Cloud uploads only over Wi-Fi (photos, videos, backups).
- Email in manual mode or with a longer refresh interval.
Pro tip:
If you use a hotspot (tethering), set the connection as “metered” (limited) on your laptop. The system (e.g. updates, cloud services) will not “eat up” your package before you have time to say “holiday”.
Trick 4: Use your hotspot wisely and plan synchronisation
Why it works:
Sharing internet with a laptop or tablet is convenient — but it is also the fastest way to make your package “evaporate”. Computer programs are “data-hungry”: system updates, cloud services, email clients and work tools.
How to minimise costs:
- On your laptop, set the network as a metered connection (limited).
- Block large updates outside Wi-Fi.
- Schedule photo and file synchronisation for the evening at the hotel (Wi-Fi), not while travelling.
- Set limits in cloud apps (e.g. “pause synchronisation on mobile data”).
- Whenever possible, work on documents offline and synchronise only after reconnecting to Wi-Fi.
When a hotspot makes sense:
- Short bursts of work: replying to urgent emails, downloading a small file or sending a document.
- Emergency situations (navigation on a larger screen, a short online meeting).
Trick 5: Choose a plan for your route and monitor usage — control every gigabyte
Why it works:
We overpay most when the plan does not match the route: for example, a global package on a trip only through the EU, or a package that is too small when using maps and video intensively. It is worth choosing a plan based on the number of countries, trip length, internet usage style, remote-work needs and possible hotspot use.
How to choose a package:
- Region vs. world: if you are travelling only around Europe, consider a regional plan; for a mixed route (EU + outside the EU), a global plan can be convenient.
- Duration: smaller packages are enough for weekends, while a month-long trip calls for larger ones (often more cost-effective per 1 GB).
- Usage style: maps + messengers use less data than video conferences and HD streaming.
- Plan for “what if…” It is always better to have the option of quickly topping up in the app than to overpay for roaming.
A second, “mid-article” mention of the tool:
Halfway through the text, it is worth remembering that the eSIM app lets you check remaining data, quickly top up and choose another plan without looking for a SIM card shop.
Mini guide: how to install an eSIM and what to remember
Installation in practice:
- Open the Yesim app on your phone.
- Choose the country/region and a data package suited to your trip.
- Follow the eSIM profile installation instructions (usually this involves scanning or installing directly from the app).
- After installation, turn on mobile data and set the eSIM profile as the default for mobile internet.
Compatibility and convenience:
- The eSIM works alongside your physical card (Dual SIM).
- You can switch profiles depending on the country or your needs.
- You can check usage, top up your package or change your plan at any time.
Starter code:
During your first activation, enter YESIMULMNE10 — new users receive 10% off.
Example saving scenarios
3–4-day city break:
- Offline maps + messengers → a small package is fully sufficient.
- Use the hotspot only “in an emergency” and briefly.
- Data saving enabled from the start of the trip.
Road trip through 2–3 countries:
- Regional plan (Europe), with predictable costs in several countries.
- Offline maps for the whole week, with photo synchronisation only over Wi-Fi.
- A second eSIM profile activated while travelling through a transit country.
Working remotely while travelling:
- Schedule video calls over a stable connection (e.g. hotel Wi-Fi).
- Download materials in advance (offline cache); make large uploads after connecting to Wi-Fi.
- For video conferences, set lower video quality when using a mobile package.
Data-saving checklist before departure
- Offline maps downloaded for the entire region.
- Data-saving mode enabled (phone and apps).
- Cloud backups and updates — Wi-Fi only.
- Video quality settings lowered (streaming/messengers).
- Hotspot: “metered connection” selected on the laptop.
- Data plan matched to the route (region vs. world) and usage style.
- Code YESIMULMNE10saved for the first purchase.
Security and digital hygiene while travelling
Saving data is not everything. Remember about security:
- Treat public Wi-Fi with caution; avoid logging in to banking and company panels.
- Perform security updates before departure, preferably over Wi-Fi.
- Separate personal and work profiles — Dual SIM (physical + eSIM) makes it easier to stay organised and in control.
Summary: lower costs, more peace of mind on the road
The greatest savings come from combining several simple habits: using an eSIM instead of roaming, offline and “offline-first” maps, data-saving mode, a sensible hotspot and a well-chosen plan. This way, you pay for what you actually need, rather than for “background” activity running without your knowledge.
If you want to keep your internet under control from day one — install the eSIM app, activate a package before departure and remember the starter code: YESIMULMNE10.
