Proximus Daily Roaming Pass or Travel eSIM: the Calculator
Proximus's Daily Roaming Pass costs €7.49 or €13.49 a day, capped at 8 days a month. Work out whether it beats a travel eSIM or Orange's pass for your stay outside the EU.
Outside the European Union, a travel eSIM almost always costs less than Proximus's Daily Roaming Pass, which comes to €7.49 or €13.49 a day. On a long stay within one month, though, the cap of 8 billed days can flip the result. The calculator below settles it for your trip, on rates collected on 21 October 2026.
It compares your Belgian operator's option with a travel eSIM, for the same length of stay and the same data volume. The prefilled rates come from the official pages of Proximus, Orange and Holafly, and each one can be changed: if your country sits in another zone or a price has moved, correct it before reading the result.
Roaming pass or travel eSIM: the calculation
Your Belgian operator’s option
Travel eSIM
A travel eSIM of this kind usually provides data only, with no number: calls and SMS go through your Belgian line or an app.
Operator pass
€59.92
8 billed days
Travel eSIM· cheapest option
€33.90
10-day plan
Difference: €26.02
Tipping point, at equal daily use: the eSIM is cheaper for a stay of 1 to 15 days, the pass is cheaper or equal for the other lengths.
The cap on billed days freezes the pass price beyond the cap: that is what puts it back in front on long stays.
Lengths from 1 to 30 days, same use per day, stay equal to days of use, a single calendar month.
With an eSIM, keep your Belgian line for SMS but turn off its data roaming. At Proximus, answering a call or sending more than two SMS a day activates a 24-hour Daily Roaming Pass on its own, hence the line above. At other operators, calls outside a pass are billed at their roaming rate, not priced here.
Assumptions and sources (collected 21/10/2026)
1. Proximus Daily Roaming Pass: €7.49 per day in zone A, €13.49 in zone B, at most 8 passes billed per calendar month (€59.92 or €107.92), then free until the end of the month as long as the plan is not used up. Source: proximus.be, Daily Roaming Pass page.
2. Orange Daily Travel: €4 per day, 1 GB per day, about 50 non-EU countries. Source: Orange Belgium press release of 13/07/2026.
3. Orange Travel Pass: €30, 7 GB, 120 minutes, 120 SMS, 15 days, TOP50 non-EU countries. Source: orange.be, Roaming options page.
4. Holafly United States eSIM, unlimited data: €3.79 (1 day) to €68.90 (30 days). The calculation takes the shortest plan that covers the stay. Source: esim.holafly.com.
5. Flat-rate pass and eSIM entered by hand: the number of passes is the larger of the two needs, in days of validity and in GB.
6. Belgian legal cap on out-of-bundle data: cut-off at €50 excl. VAT, i.e. €60.50 incl. VAT, per billing period (BIPT decision of 20/11/2012). It does not replace a pass.

How much does Proximus's Daily Roaming Pass cost over a stay?
The Daily Roaming Pass costs €7.49 per 24-hour period in zone A and €13.49 in zone B, and Proximus never bills more than 8 of them per calendar month. The cost of a stay is therefore the number of days of use, capped at 8, multiplied by the zone rate: €59.92 or €107.92 at most.
You do not buy the pass: it activates by itself, for 24 hours, as soon as you use data, make or receive a call, or send more than two SMS in a day. It lets you use the minutes, SMS and gigabytes of your Belgian plan, with no volume of its own. Zone A includes the United States, Canada, Switzerland, Turkey, Japan and Australia; zone B includes Vietnam, Colombia, the Philippines and Argentina. A few countries, such as Cuba and Lebanon, are covered by no pass at all.
A week in Montreal using your phone every day costs 7 × 7.49 = €52.43. Stretch it to twelve days in the same month and the bill stops at €59.92, since days 9 to 12 are free.
How does the calculator compare the pass and the eSIM?
It works out the cost of the two scenarios separately for the same length of stay and the same data volume, then shows the difference and the lengths of stay for which the eSIM wins. Three pricing mechanisms coexist, and each has its own formula.
For a pass billed per day (Proximus, Orange Daily Travel), the cost is the number of days of use multiplied by the daily price. If the operator caps the billed days, the calculation keeps the smaller of the two numbers: days of use, or the cap multiplied by the number of calendar months crossed. That is why the tool asks whether the stay spans two months.
For a flat-rate pass (Orange Travel Pass, another operator's pass), you need as many passes as the tighter of the two limits demands: validity in days or volume in GB. Twelve gigabytes over fourteen days with a 7 GB pass valid for 15 days requires two, because the volume runs out before the date.
For the eSIM, the tool takes the shortest plan that covers the whole stay in Holafly's United States price list (1, 3, 5, 7, 10, 15 or 30 days, unlimited data). When you enter your own eSIM, it applies the same rule as for a flat-rate pass. On top of that comes a line most comparisons forget: the days you answer on your Proximus line, each of which triggers a Daily Roaming Pass.
The tipping point is found by replaying both scenarios over every length from 1 to 30 days, at constant daily use. The result is not always a single figure: eSIM price steps and the Proximus cap sometimes create several ranges, and the tool shows them as they are instead of smoothing them out.
Example: ten days in the United States, what do you pay?
With the Daily Roaming Pass, ten days of use in the United States cost €59.92, and a ten-day unlimited Holafly eSIM €33.90. The eSIM saves €26.02, provided you do not answer calls on the Belgian line.
The calculation by hand, for a traveller away from 3 to 12 October who expects about 8 GB of maps, messaging and photos:
- Proximus, zone A: 10 days of use, capped at 8 billed days, i.e. 8 × 7.49 = €59.92.
- Holafly United States eSIM: the shortest plan covering 10 days is the 10-day one, at €33.90. Since data is unlimited, the 8 GB changes nothing.
- Difference: €59.92 minus €33.90, i.e. €26.02 in favour of the eSIM.
- The traveller gets two calls from the bank, on two different days, and answers: two Daily Roaming Passes activate, i.e. 2 × 7.49 = €14.98. The eSIM then comes to €48.88, and the difference drops to €11.04.
Stretch the same trip to sixteen days in the same month: the pass stays at €59.92 while the eSIM moves to the 30-day plan, at €68.90. The pass becomes cheaper again, by €8.98. The tipping point shown by the tool for this profile says it in one line: the eSIM wins from 1 to 15 days, the pass after that.
Orange Daily Travel or Travel Pass: which beats the eSIM over two weeks?
Over fourteen days in the United States with 12 GB, Orange Daily Travel costs €56, the Travel Pass €60 and the 15-day Holafly eSIM €46.90. The eSIM wins by €9.10 against Daily Travel and by €13.10 against the Travel Pass.
Daily Travel charges €4 per day of use and gives 1 GB a day: 14 × 4 = €56, and 12 GB spread over 14 days stays below the daily gigabyte. The Travel Pass gives 7 GB for €30 and 15 days: 12 GB requires two, i.e. €60, whereas the length of stay only called for one. With 6 GB instead of 12, a single Travel Pass is enough and costs €30, less than the eSIM.
The countries covered differ from one plan to the other: Daily Travel targets about fifty destinations outside the EU, the Travel Pass Orange's TOP50 countries. Check that your destination is on the list before relying on the result.
From how many days does the eSIM pay off?
For use of 0.8 GB a day in the United States, the eSIM is the cheapest from 3 to 14 days against every option. Proximus's zone A Daily Roaming Pass moves back in front from 16 days within one month, thanks to its cap.
The table below applies the calculator's formulas to the rates collected on 21/10/2026, for a stay within a single calendar month, except for the last row. The cheapest in each row is in bold.
| Length (0.8 GB a day) | Proximus zone A | Proximus zone B | Orange Daily Travel | Orange Travel Pass | Holafly United States eSIM |
|---|---|---|---|---|---|
| 3 days | €22.47 | €40.47 | €12.00 | €30.00 | €11.37 |
| 5 days | €37.45 | €67.45 | €20.00 | €30.00 | €18.50 |
| 7 days | €52.43 | €94.43 | €28.00 | €30.00 | €25.50 |
| 10 days | €59.92 | €107.92 | €40.00 | €60.00 | €33.90 |
| 14 days | €59.92 | €107.92 | €56.00 | €60.00 | €46.90 |
| 21 days | €59.92 | €107.92 | €84.00 | €90.00 | €68.90 |
| 30 days, same month | €59.92 | €107.92 | €120.00 | €120.00 | €68.90 |
| 30 days, over two months | €119.84 | €215.84 | €120.00 | €120.00 | €68.90 |
The zone B column only gives an indicative eSIM comparison, since the Holafly price list used is the United States one: for Vietnam or Colombia, enter the price of the eSIM for the country you are visiting. The lesson stays the same, only sharper: at €13.49 a day, zone B rarely makes the pass competitive before the cap.
Why can an eSIM still trigger the Daily Roaming Pass?
Because the Proximus pass is not triggered by data alone. A call made or received, or more than two SMS sent in a day, activates a 24-hour pass, even if all your data goes through the eSIM.
Most travellers keep their Belgian line switched on, and rightly so: it receives the bank's confirmation SMS, which stay free to receive. The trap is answering. Turning off data roaming on the Belgian line is not enough, since the call triggers the pass on its own. To stay reachable without paying, divert calls to voicemail or ask people to reach you through a calling app over the eSIM's data.
Proximus adds a second limit few travellers know about: a €60 monthly data limit abroad, in which passes are counted. In zone B, eight passes come to €107.92: raise the limit to €121 before leaving, or the pass may stop activating during the stay. The calculator shows this alert as soon as the zone B cost exceeds €60.
What happens if you take neither a pass nor an eSIM?
Without a pass, data is billed at the operator's standard roaming rate, which can reach several euros per megabyte depending on the country. Belgian rules require the operator to cut mobile data when out-of-bundle use reaches €50 excl. VAT, i.e. €60.50 incl. VAT, over a billing period.
That cap, set by a 2012 BIPT decision, prevents the four-figure bill but not the €60 one, and it covers neither calls nor SMS. At Proximus, the question rarely arises: the Daily Roaming Pass activates by itself. With an operator that has no automatic pass, leaving with nothing means paying the standard rate until the cut-off. Our guide to out-of-bundle charges on a telecom bill explains how to dispute an overrun.
Which mistakes distort the calculator's result?
The first is getting the zone wrong: Switzerland and Turkey are in zone A at Proximus, Colombia and Vietnam in zone B, and a country that is not covered has no pass at all. Check your operator's page and correct the daily price if needed.
The other common mistakes, in order of how much they cost:
- Counting travel days instead of days of use. The Daily Roaming Pass is only paid on the days it activates. A three-day trek with no signal, phone in airplane mode, takes three days out of the calculation.
- Forgetting the change of month. The 8-day cap counts per calendar month. A stay from the 25th to the 10th of the next month can cost two caps.
- Taking the Travel Pass for a duration plan. You need another one as soon as the 7 GB are used, even on the third day.
- Assuming the eSIM gives you a number. Travel eSIMs such as Holafly's provide data only: no regular calls and no SMS, except through an app.
- Forgetting the Belgian plan. The Daily Roaming Pass draws on your Belgian gigabytes: with a 5 GB plan, an 8 GB stay stops halfway.
The calculator does not know your contract. It does not price calls to a third country, which the Proximus pass excludes, special numbers, eSIM sellers' temporary promotions, or your phone's compatibility, covered in our guide eSIM: which Belgian operator offers it. It gives an estimate, not a bill: only your operator's and the eSIM seller's terms are binding.
