Holafly vs AeroSims for Germany (2026): Unlimited Price vs the 10 GB Question

Updated August 2026 · Prices verified on both providers’ product pages and subject to change

Berlin’s museums, Munich’s beer halls in festival season, castles on the Rhine and 300 km/h on the ICE — Germany rewards being online, from train tickets to last-minute table bookings. We ran the two big unlimited-eSIM contenders through the same price check so you can decide in two minutes. Short version: the winner depends entirely on how much data you actually use.

The quick verdict

Pick AeroSims for unlimited on any trip up to three weeks: it now undercuts Holafly at every standard length up to 15 days — $24.90 vs $27.50 for a week, $17.90 vs $20.50 for 5 days, $45.90 vs $50.50 for 15 — with a price printed for every single length from 1 to 90 days, so an 8-day trip costs an 8-day price ($27.74).

Pick Holafly for a month of unlimited: its 30-day plan wins at $73.90 vs $87.90. That’s the honest math and we’re printing it.

Most travelers should skip unlimited entirely: Holafly’s Germany page sells unlimited plans only. AeroSims’ Germany data packages run from $3.90 for 3 GB to 50 GB sizes — 10 GB costs $8.90, valid 30 days: a normal week or two online for a fraction of any unlimited plan’s price.

The price gap, in real trips

On the standard lengths AeroSims is now the cheaper unlimited: $24.90 vs $27.50 for a week, $32.90 vs $36.50 for 10 days, $45.90 vs $50.50 for 15. Only the month still goes to Holafly, $73.90 vs $87.90. Real itineraries rarely land exactly on 7 or 10 days, and our page carries a price for each one: an 8-day Berlin–Dresden–Munich run is $27.74, a 4-day city break $14.43. Holafly lets you pick other durations through a calendar too, but publishes prices only for the six lengths above — those six are what we compare.

But the comparison every traveler should actually make is different: if your usage is normal — maps, WhatsApp, social, train apps — a fixed 10 GB package for $8.90 covers one to two German weeks for a third of either unlimited plan. That’s the option this whole category quietly hopes you won’t notice.

The option Holafly doesn’t have: fixed data packages

For Germany, Holafly sells unlimited only. AeroSims sells both lines, so you can match the plan to the trip instead of the other way round (all valid 30 days):

Data (30 days) AeroSims Covers roughly
3 GB $3.90 A city weekend
5 GB $4.90 A light-use week
10 GB $8.90 One to two normal weeks
20 GB $16.90 Two heavy weeks

Long stays get the widest gap of all: 50 GB valid 180 days for $44.90 — study semesters and remote-work stints don’t need an unlimited plan renewed monthly. Every size lives on one page: AeroSims Germany data packages — see where Germany sits in the eSIM Price Index 2026.

“Unlimited” fine print: what fair use really means

Every unlimited travel eSIM has a fair-use policy, set by the local network. The same applies to the AeroSims plan. After a daily high-speed allowance the connection continues at a reduced speed until the next day — maps and messaging keep working; streaming gets slow.

Holafly’s FAQ describes its fair-use rule as a temporary measure applied for no more than a day; the threshold isn’t published on the product page. Neither plan is infinite — the honest question is whether your usage would ever notice.

Oktoberfest, trade fairs and other data-hungry weeks

Germany’s peak moments are exactly when you want your own data: Oktoberfest in late September, the Christmas markets from late November, and the year-round trade-fair circuit in Frankfurt, Cologne and Hanover. Festival grounds and packed fairgrounds are where public Wi-Fi collapses and meeting points shift by the minute — and where hotel prices already punished your budget. A $8.90 package or an unlimited plan bought for exactly those days is the cheap part of that week. One practical note: this is a Germany plan — if your itinerary crosses borders (a Salzburg day trip, Strasbourg, Basel), look at a multi-country Europe package instead, or a separate Switzerland plan for the Swiss leg.

Coverage: cities, valleys and the ICE at speed

The AeroSims Germany eSIM runs on O2 and Vodafone with 4G everywhere tourists go and 5G in the big cities. Berlin, Munich, Hamburg, Frankfurt and Cologne are all solid. Germany’s well-known rural dead zones (“Funklöcher”) and some train stretches affect every network in the country — a plan on two networks at least lets your phone pick whichever signal survives the valley.

Germany eSIM questions travelers ask

Is AeroSims cheaper than Holafly for Germany?

Yes — at every length in Holafly’s published price table up to 15 days ($24.90 vs $27.50 for a week, $45.90 vs $50.50 for 15 days). At a full month the tables turn: Holafly keeps the 30-day plan ($73.90 vs $87.90) and offers a longer refund window. Fixed data packages stay AeroSims-only for Germany: 10 GB costs $8.90.

Do I need a German SIM registration or ID for an eSIM?

No. Germany’s ID rules apply to SIM cards bought from German providers. A travel eSIM is bought abroad and needs no registration.

What does the fair-use policy mean in practice?

A fair-use policy applies, set by the local network: after a daily high-speed allowance the connection continues at a reduced speed until the next day. Most travelers never come close to it on a normal day of maps, messaging and social.

Does my WhatsApp number keep working?

Yes. The eSIM is data-only; your home SIM stays installed for calls and SMS codes, and WhatsApp keeps your existing number.

When does the plan start counting days?

When the eSIM first connects to a German network — not at purchase. Install it at home days before you fly and lose nothing.

Bottom line

If your trip is a month long and unlimited is non-negotiable, Holafly’s sticker price wins Germany and we won’t argue. For trips up to about three weeks, AeroSims’ unlimited now costs less — at the standard lengths and between them — and for normal usage the $8.90-for-10-GB package still beats everything above it. Decide by your usage, not by the word “unlimited”.
