Compare mobile plans →1. Students in Luxembourg: a specific mobile profile
The University of Luxembourg enrolls over 7,200 students (2024-2025 academic data), of whom around 60% are international students from more than 150 nationalities. It is one of Europe’s most international universities. This population is joined by Luxembourgish students who return home on weekends and holidays, numerous interns, and PhD students.
This population has very specific mobile needs: a tight budget in one of Europe’s most expensive cities, reliable connectivity across the EEA (Erasmus mobility is mandatory for Bachelor students at the University of Luxembourg), data for everyday digital use, and above all a no-contract plan — study durations, internships and Erasmus periods all vary.
Erasmus mobility is mandatory for Bachelor students at the University of Luxembourg — all undergraduate students must spend at least one semester at a foreign university. The EU « Roam Like At Home » regulation ensures your Luxembourg plan works at no extra cost throughout the EEA during this period.
The University of Luxembourg operates across two main campuses: Belval campus (Esch-sur-Alzette) and the Luxembourg City campus. Both are covered by the 5G networks of all three Luxembourg operators. The eduroam Wi-Fi network is available on both campuses — a valuable tool for reducing mobile data usage.

2. POST — the special under-26 offer
POST Luxembourg offers a plan exclusively for 18 to 25-year-olds: a POP Mobile plan at a preferential rate. The offer is automatically renewed until the subscriber’s 26th birthday, with no need to re-commit.
| Feature | Detail |
|---|---|
| Eligibility | Ages 18 to 25 inclusive — must be subscribed in the person’s own name |
| Plan included | POP Mobile L at a reduced rate (calls, SMS, data — check POST for exact volume and price in June 2026) |
| Duration | Automatically renewed until the day of the 26th birthday |
| How to subscribe | In an Espace POST store only — not available online |
| Network | POST — Luxembourg’s #1 network, most extensive 5G coverage |
Source: POST Luxembourg — Special offers and promotions. Verify the current rate and conditions in June 2026 directly in a POST store — the offer may change.
This offer is particularly attractive for Luxembourgish students or those staying long-term in the Grand Duchy, who get access to POST’s network (the most extensive, including rural and border areas) at a reduced price without having to renew annually. For students on a short stay (5-6 month Erasmus), no-contract plans from Tango or Orange are more suitable.
3. The cheapest mobile plans in Luxembourg for students
Beyond POST’s youth offer, here are the most accessible options on the Luxembourg market for a student on a tight budget.
Tango — entry-level no-contract plans
Tango Mini — the bare minimum
2 GB of data and 200 minutes/SMS usable in Luxembourg and Europe, no contract. Ideal for a student who relies almost entirely on campus and residence Wi-Fi, and only needs mobile connectivity for occasional calls and browsing on the go. Usage beyond the plan is billed per unit.
Tango GO)) mobile S — the first real no-contract plan
6 GB of data plus calls and SMS included in Luxembourg and Europe, national 5G, no contract. Data Plus is included: unused data rolls over automatically to the following month. During exam periods when you’re on the library Wi-Fi, your GB accumulate for more active months — at no extra cost.
Tango GO)) mobile M — the balanced plan
20 GB of data plus calls and SMS included in Luxembourg and Europe, national 5G, no contract. Data Plus (unused data rolls over) and Data Boost (double your volume once a year) included. Data Boost is useful for intensive periods — internship travel, start-of-term rush, end-of-studies trip.
POST BASIC — for ultra-tight budgets
POST offers the BASIC plan with a fixed monthly fee of just €2. You then pay only for what you consume, at pay-as-you-go rates. It is the lowest fixed monthly cost on the market for a student who very rarely uses mobile data outside of Wi-Fi. The downside: without an included allowance, usage costs can add up quickly if you use the mobile network regularly.
Orange Luxembourg — competitive no-contract plans
Orange Luxembourg offers no-contract plans with a good data-to-price ratio and regular promotional offers. Check Switchr for active offers in June 2026.
Tango Mini (2 GB): covers bus/train commutes and occasional outings
Tango GO)) S (6 GB): recommended if you go out regularly (GPS, music, social media)
Tango GO)) M (20 GB): comfortable if you have an active internship or travel frequently
With Data Plus (Tango), GB saved in a quiet month roll over automatically — zero waste
4. Mobile data vs. campus Wi-Fi: the smart strategy to save money
The vast majority of students at the University of Luxembourg have access to Wi-Fi at their places of study: Belval campus, Luxembourg City campus, university libraries and student residences. This significantly changes the mobile plan equation: you don’t need a huge data allowance if you optimise your Wi-Fi usage.
eduroam — your ally during Erasmus: both University of Luxembourg campuses use the eduroam Wi-Fi network. If you keep your eduroam credentials, you can connect for free at thousands of partner universities across Europe — including during your Erasmus semester, without using your mobile data.
Configure your apps to save data
Audio and video streaming
Set Netflix, Spotify and YouTube to download or cache content on Wi-Fi only. Your Spotify library can be downloaded on campus Wi-Fi for offline listening during your commute.
App updates and cloud sync
Turn off automatic app updates over mobile data (iOS and Android) — they will only update on Wi-Fi. Restrict iCloud, Google Drive or OneDrive to Wi-Fi to prevent photos and files consuming your data in the background.
Academic video calls
One hour of Teams or Zoom in HD uses around 1.5 GB. For online lectures or group meetings, always connect to Wi-Fi when available. With Tango’s Data Plus, months spent mainly on Wi-Fi build up a reserve for more active periods.
Realistic monthly usage estimate: for a student with Wi-Fi in their residence, lecture rooms and library, real mobile network usage is typically limited to commuting, evenings out and situations without reliable Wi-Fi. In this scenario, 6 to 15 GB per month is more than sufficient for most student profiles. See also our guide on mobile data usage in Luxembourg to refine your estimate.
5. Why no-contract is essential for students
Student life is unpredictable by nature: a 6-month Erasmus in Berlin, an internship in Amsterdam, a return to your home country over the summer. Being locked into a 12 or 24-month contract can become an expensive constraint.
No-contract plan
- Cancel at any time with no penalty
- Switch plan to match needs (internship, Erasmus)
- Switch operator if a better offer comes along
- Suited to variable study and internship durations
- Not always the most generous plan for the price
Fixed-term contract
- Sometimes more generous data volumes at the same price
- POST network #1 (most extensive coverage)
- Early termination fees if you leave before the end
- Less flexible for Erasmus or returning abroad
6. On outgoing Erasmus: managing your plan during your semester abroad
At the University of Luxembourg, all Bachelor students must complete a semester abroad — it is a degree requirement. The university partners with over 250 institutions in Europe and worldwide.
EEA roaming covers most Erasmus destinations
Thanks to the EU « Roam Like At Home » regulation (EU 2022/612, valid until 2032), your Luxembourg plan works across the entire EEA (EU + Iceland, Liechtenstein, Norway) under the same conditions as in Luxembourg. If your Erasmus is in France, Germany, Belgium, Spain, Italy or any other EEA country, you don’t need to do anything special. For more details, see our guide on roaming in Luxembourg.
The Fair Use clause applies for longer stays: if you spend more than 4 consecutive months abroad and your data usage abroad exceeds your usual usage in Luxembourg, your operator may apply restrictions (EU Regulation 2022/612). In practice, if you use your host university’s Wi-Fi for intensive use (streaming, cloud), the risk is limited.
Three strategies depending on the length of your Erasmus
Keep your Luxembourg plan
You keep your +352 number, EEA roaming covers your normal usage. Recommended if your Erasmus is a short semester in an EEA country. Switch to a Tango Mini or GO)) S during this period to reduce costs if you have Wi-Fi at the host campus.
Luxembourg SIM + local eSIM
If your smartphone supports eSIM, combine your physical Luxembourg SIM with a local eSIM in your host country. You remain reachable on your +352 number while benefiting from an affordable local plan for daily use. For more details, see our eSIM guide for Luxembourg.
Local SIM in the host country
For an Erasmus outside the EEA (USA, Canada, Asia…), a local SIM is recommended for daily use to avoid high roaming charges. Keep your Luxembourg SIM to remain reachable on your +352 number.
7. Incoming Erasmus and international students: getting set up on arrival in Luxembourg
If you are coming to Luxembourg for an Erasmus semester, an international exchange or full studies, here is how to get connected quickly and affordably.
On arrival: prepaid SIM with no bank account needed
Even before you have opened a bank account, you can buy a prepaid SIM card from POST (TipTop range) or Tango (Tango Prepaid) at Auchan and Cactus supermarkets, at operator stores, or at Luxembourg Airport in the arrivals area. These cards work without a bank account or any commitment — you top up as needed. You get a Luxembourg +352 number immediately, usable in Luxembourg and across Europe.
Then subscribe to a monthly plan
Once you have a SEPA IBAN (Luxembourg, French, Belgian, German or any other SEPA country account), you can subscribe to a no-contract monthly plan from Tango or Orange Luxembourg online. Your prepaid number can be kept on your new monthly plan through number portability.
For students outside the SEPA zone: if you don’t have a bank account yet, the prepaid card is the ideal solution while you open one. POST Luxembourg also offers bank accounts via POST Finance — a convenient way to open an account and subscribe to a mobile plan in the same place.
Which plan for a 5-6 month incoming Erasmus?
For a semester stay in Luxembourg, Tango GO)) mobile S or M, no contract is the ideal solution: a +352 number, data for daily use, a monthly subscription cancellable at any time with no penalty. If you have Wi-Fi in your residence and on campus, the GO)) S (6 GB) is generally sufficient. If you go out frequently, the GO)) M (20 GB) gives more headroom. In all cases, the plan works across Europe during your weekends and trips.
Also looking for a fixed internet connection? If you are renting privately rather than in a university residence, see our guide on internet for international residents in Luxembourg for short-term options.

9. Keeping your mobile budget under control as a student in Luxembourg
Luxembourg City is one of the most expensive cities in Europe. Every euro saved on your mobile plan counts. Here are the key habits to adopt.
Enable the blocked plan option
Regardless of your operator, ask about the blocked plan option. Available from POST and Tango, this option prevents any usage beyond your plan — no bill surprises at the end of the month. It is included by default on some Tango plans and available as an add-on from POST.
Use Data Plus to avoid waste (Tango)
Tango’s Data Plus feature (rollover of unused data to the following month) is valuable for students whose usage varies by period. During exam periods when you’re on Wi-Fi, your GB accumulate for more active months — a waste-protection feature at no extra cost.
Compare plans regularly
The Luxembourg mobile market evolves regularly. Orange Luxembourg offers periodic promotional deals with excellent data-to-price ratios. With a no-contract plan, you can switch operator at any time — no penalty.
During the academic year: Tango GO)) S or M depending on your activity
During summer (fewer trips, Wi-Fi at family or internship): switch to Tango Mini
With a no-contract plan, you adjust your level each month to match your activity — no penalty
