HelloRoam, the one-profile regional option, covers 33 destinations on its Europe plan and rides O2 and Vodafone 5G in Germany, with a top-up on every plan. Ubigi, the long-stay specialist, lists $12.50 for 10 GB over 30 days there. Airalo, the short-trip pick, lists $10.50 for 5 GB over 7 days.
The Data Spend On A Ten-Day Paris, Berlin And Barcelona Run, Added Up
Three cities, three countries, ten days. Bought one country at a time, that is three purchases on one phone.
HelloRoam prices 5 GB over 30 days at $9.49 in France, $8.81 in Germany and $7.92 in Spain. Added up, that is $26.22 for 15 GB, and few ten-day travellers get near it.
Drop to the entry rung and the total falls to $9.67 for 3 GB, at $3.99 in France and $2.84 in each of the others. Those plans run 7 days, so a ten-day itinerary outlives all three.
Currency Conversion, Unused Gigabytes And Duplicate Plans Push Up The Total
Three costs sit under that $26.22, and none appear on a checkout page.
Unused data. Small plans carry the worst rate per gigabyte. In Germany, $8.81 for 5 GB over 30 days is $1.76 a gigabyte, against $0.61 at $30.60 for 50 GB over 30 days.
Overlapping validity. Buy the Paris plan on day one and the Barcelona plan on day six, and both run through the days between.
The card. Every figure here is in US dollars, and your issuer sets the rate you actually pay.
The Same German 10 GB Plan Over 30 Days, Bought Six Different Ways
Germany makes the fairest test, because every provider below resells the same German operators. O2 and Vodafone are German carriers, and a plan sold for Germany attaches to one of them whoever badges the QR code. The network column is not the variable here.
These rows are ranked on how much of a European itinerary one purchase covers, from a profile that crosses borders down to a plan that counts only days. Price is reported in every row but is not the axis, and the cheapest German 10 GB month here belongs to Ubigi at $12.50.
The HelloRoam Travel Data Price Index, August 2026: 10 GB Over 30 Days In Germany
| Rank | Provider | Plan and price | Host network | Best for |
| 1 | HelloRoam | $12.74 for 10 GB over 30 days | O2 and Vodafone, both 5G | One profile that carries a border-crossing route across 33 destinations |
| 2 | Ubigi | $12.50 for 10 GB over 30 days | O2 and Vodafone | A single country held for a full month, at the lowest 10 GB rate here |
| 3 | Nomad | $14.00 for 10 GB over 30 days | O2 and Vodafone | One 30-day term at every size |
| 4 | Airalo | $16.00 for 10 GB over 30 days | O2 and Vodafone | A stay measured in days rather than in months |
| 5 | Saily | $16.99 for 10 GB over 30 days | O2 and Vodafone | A single country up to 20 GB, with ad and tracker blocking built in |
| 6 | Holafly | $27.50 for unlimited data over 7 days, with no size tiers | O2 and Vodafone | Days counted instead of gigabytes |
Method: German rates sampled 1 August 2026, held to 10 GB over 30 days so the rows compare. Holafly sells no sized German plan, so its own 7-day window is shown instead. Sim Local is left out because no German rate could be confirmed for it.
Five of the six providers sell 10 GB over 30 days in Germany, and their prices run from $12.50 to $16.99, a 36% spread on the same two host networks.
One gap sits in the row directly beneath the top. Ubigi sells no 5 GB plan in Germany at all, and the 3 GB plan it does sell there runs 15 days rather than 30, so a fortnight has nothing sized for it.
Ubigi’s $12.50 does undercut the top row by $0.24 at 10 GB, a gap under 2% and a tie rather than a win. That table holds one size, and a five-city rail loop rarely stops at 10 GB. Read the full Europe eSIM price list before you settle on a size.
Each Provider On That List Is Built Around A Different Length Of Stay
1. HelloRoam: The Border-Crossing Route On One Profile, At $12.74 For 10 GB Over 30 Days
HelloRoam sells one Europe profile across 33 destinations, and 185 destinations priced individually. In Germany the ladder opens at $2.84 for 1 GB over 7 days, then climbs to a top rung of $30.60 for 50 GB over 30 days.
Every plan takes a top-up, so an overrun does not force a fresh purchase at entry-rung prices.
Prices are set per country, not blended. That same 10 GB over 30 days is $16.84 in Italy, a 32% swing on identical data.
2. Ubigi: A Single Country Held For A Full Month, At $12.50 For 10 GB Over 30 Days
Ubigi is built for travellers who stay put. Its $12.50 is the lowest 10 GB rate in this table. Fifteen gigabytes more brings the German price to $25.00 for 25 GB over 30 days, and the biggest plan it sells there is $44.00 for 50 GB over 30 days.
That $44.00 is the highest 50 GB rate of the four providers here selling one. The ladder is dear at the ceiling and missing rungs at the floor.
3. Nomad: One 30-Day Term At Every Size, At $14.00 For 10 GB Over 30 Days
Nomad is the easiest ladder to read. In Germany it charges $8.00 for 3 GB over 30 days at the light end, and a heavy month is covered at $32.00 for 50 GB over 30 days.
That consistency is the point: sizes compare without validity getting in the way.
Apart from 1 GB at $4.50 over 7 days, every sized plan is 30 days, so a three-night break pays for a month.
4. Airalo: A Stay Measured In Days Rather Than In Months, At $16.00 For 10 GB Over 30 Days
Airalo splits its German range by duration more finely than anyone here. Its 5 GB tier sells at $10.50 over 7 days, $11.00 over 15 days and $11.50 over 30 days.
That granularity is thinner than it looks. Fifty cents separates one rung from the next, and a whole dollar covers the jump from a week to a month.
On price it sits high. Its $16.00 is 28% above the lowest German rate in the table.
5. Saily: A Single Country With Ad And Tracker Blocking Built In, At $16.99 For 10 GB Over 30 Days
The team behind NordVPN also runs Saily, which is why ad and tracker blocking is built into the plan itself.
Its German ladder is short, from $4.49 for 1 GB over 7 days to $22.99 for 20 GB over 30 days.
The ceiling is the problem. Germany gets no 50 GB tier and no unlimited option, so a heavy month runs out of ladder.
6. Holafly: Days Counted Instead Of Gigabytes, At $27.50 For Unlimited Data Over 7 Days
Holafly removes the sizing decision. Germany sells as unlimited data at $11.90 over 3 days, $27.50 over 7 days and $73.90 over 30 days.
Buying that way makes sense when you cannot predict usage, or when a laptop is tethered to the phone.
It is a poor fit for light users. Someone checking maps pays what a heavy uploader pays.
Roam-Like-At-Home Stops At The Swiss, British And Turkish Borders
EU roam-like-at-home rules cover EU and EEA countries, and plenty of itineraries leave that zone. Switzerland never joined, the United Kingdom left, and Turkey sits outside.
A tariff that behaves normally in Vienna can revert to out-of-bundle rates in Zurich the same afternoon. Networks set their own day-pass rates there.
HelloRoam lists 10 GB over 30 days at $15.93 in the United Kingdom on 3, EE and O2, and at $10.69 in Turkey on Vodafone 5G.
Buying A Prepaid SIM At Charles De Gaulle Trades A Morning For A Second Number
A local French SIM can price well over a long stay. It is still the wrong tool for a short one. You queue, show ID, and pull out the SIM your bank sends codes to.
That swap is the real cost. Your home number stops receiving texts, and two-factor codes go with it.
A travel profile sits beside the SIM already in the phone. HelloRoam prices France at $13.99 for 10 GB over 30 days on Orange 5G.
Video Calls Are What Push A Two-Week Europe Plan Past 10 GB
Maps, messaging and boarding passes barely register. Video calls, photo backup and streaming on a hotel evening are what move a fortnight past 10 GB.
Price the step up rather than guessing. In Germany, moving from 10 GB to 20 GB over 30 days costs $8.25 more, and the rate per gigabyte falls from $1.27 to $1.05.
Buying short and topping up later works when the plan allows it. Without one, an overrun means a second entry-rung plan.
A Month Parked In London Is A Different Buy From A Five-Country Rail Loop
Some trips are better bought from a rival, and a data-heavy month in one city is one of them.
Ubigi sells 25 GB in the United Kingdom at $22.00 over 30 days. HelloRoam’s UK ladder steps from $28.49 for 20 GB over 30 days to $32.76 for 50 GB over 30 days, with nothing between. A London month needing roughly 25 GB gets more data for less money on Ubigi.
The rail loop reverses it. Five countries bought singly means five entry rungs.
A Topped-Up Balance Reaches The Phone Before The Next Border Crossing
Running out in Ljubljana on a Sunday is a support problem, not a shopping problem. A refill loads straight onto the profile you are already using, so there is nothing to install a second time.
Top-up is available on the HelloRoam plans in the table above. It matters most on the small rungs.
Check it before you buy, because providers differ on whether a top-up extends validity or only adds data.
Network, Coverage And Compatibility, Answered Before You Pay
No eSIM company builds towers in Europe. Each buys wholesale access from the same national operators, which is why all six rows share a network column in Germany. You can see the carrier partners behind the network before you buy.
Which Carrier Will My E SIM Connect To In Europe?
It depends on the country, not the provider. HelloRoam plans ride O2 and Vodafone in Germany and Orange in France. Spain is Movistar and Orange, Italy is Iliad, TIM and Wind, and the United Kingdom is 3, EE and O2.
Does A Regional E SIM Beat Single-Country Plans?
On a multi-country route, usually yes. Three separate 5 GB plans for Paris, Berlin and Barcelona come to $26.22 for 15 GB, most of it unused. For a fortnight in one city, a single-country plan is normally the cheaper buy.
Is E SIM Available In Europe?
Yes. Every provider in the table sells European data as a downloadable profile, delivered by QR code after purchase. No shop visit and no plastic card are involved. The constraint is the handset rather than the country, and most phones sold in recent years qualify.
What Network Does An E SIM Use In Europe?
It uses a national operator’s network under a wholesale agreement, because no eSIM seller owns towers. In Germany that means O2 and Vodafone for all six providers listed here. Your phone registers on whichever host the plan names, then re-registers at the next border.
Does Europe Support E SIM?
Yes, and it has across the major markets for years. Support sits with the operators, and every carrier named above already carries eSIM traffic. Check your device rather than your destination, because older handsets cannot hold a second profile at all.
Do E SIM Plans Work In Europe?
Yes, and the detail worth knowing is when the clock starts. Most plans begin counting on first connection in the destination rather than at purchase, so installing the night before you fly does not spend a day of validity.
