Roaming charges are the tax nobody voted for — and for travellers crossing multiple countries, they compound fast. Firsty eSIM takes a different approach: one eSIM installed once, working in 185+ countries, with plans starting from free. A Firsty promo code cuts 10% off paid plans, and BudgetFitter holds the verified discount. The app has a 4.4/5 rating on the App Store and routes through one of the world’s largest telecoms networks.
Firsty is a Dutch eSIM provider founded in Amsterdam in 2023. Unlike traditional travel SIMs that require a physical swap at every border, Firsty installs once via its iOS or Android app and activates in whichever country you land in — no QR code scanning, no carrier switching, no new SIM to buy. Your home SIM stays in the phone handling calls and texts; Firsty handles data.
The setup takes a few minutes: install the app, create an account, and install the eSIM profile. From that point, the eSIM is permanent on the device. Activate a plan before a trip, schedule a future activation date, or switch plans between destinations. A usage monitor inside the app tracks data in real time.
Firsty runs a three-tier structure across free, daily, and monthly plans — all valid across 185+ countries on the same installed eSIM.
Firsty Free is the headline differentiator: a genuinely free tier available in every supported country. Watch a short ad (20–30 seconds) to unlock 30 minutes of data. Stack up to 12 ads for roughly five hours of connectivity per session. Speed is throttled — suitable for WhatsApp, maps, and Uber — with a 300MB daily cap. No credit card required.
Daily plans step up to full speeds: Comfort+ from €1 per day (~750MB, covers social media, video calls, and navigation) and First Class from €2.50 per day (~5GB with hotspot). Monthly plans suit frequent travellers and digital nomads — Economy at €4.50/month for 1.5GB, Comfort+ at €19.50/month for 10GB, and First Class at €39.50/month for 40GB high-speed plus unlimited throttled data with tethering included. Monthly plans cancel, upgrade, or downgrade at any time with no penalty.
The eSIM market is growing — BudgetFitter’s guide to the best eSIM options covers the main alternatives — but Firsty holds a few positions no direct competitor matches. Airalo and Holafly both require purchasing a new eSIM package per destination or region; Firsty installs once and works everywhere on the same profile. Holafly and Nomad offer no free tier; Airalo’s free offer is limited to select destinations. Firsty’s monthly subscription model is also rare in this category — most rivals sell fixed data packages only.
In independent speed tests, Firsty outperformed Holafly in every tested country, recording 109 Mbps in the UK and 94.5 Mbps in South Korea. The network routes through Singtel, one of the largest global telecoms operators.

The code is revealed via the BudgetFitter deal page — copy it and apply it at checkout inside the Firsty app. The free tier requires no code and no payment. BudgetFitter updates this page when the offer changes.
Firsty supports dual SIM throughout — the eSIM handles data while a physical SIM retains calls and texts. For travellers who cover several countries on a single trip, the combination of the free tier for light use and a daily plan for heavier days offers a level of flexibility no single fixed-data package matches.
