You land at Prague Vaclav Havel Airport (PRG), tired but ready. The arrivals hall is busy, and you just want to check your messages, find your transfer, and let your family know you have arrived. With a Slashtel eSIM, you can do that the moment you touch down. No hunting for a local SIM kiosk, no queueing, no need to hand over your passport.
Slashtel sells data-only eSIMs for the Czech Republic. You buy online before you travel, and your QR code arrives by email within a minute. Install it at home on Wi-Fi, and it activates when it first connects in the Czech Republic. Prices start from $1.79. There is no contract, no local address needed, and no hidden fees. It is just data, so you keep your usual number for calls and texts.
UK travellers often visit the Czech Republic for city breaks and group trips. Prague is a favourite for stag dos, hen parties, and weekend getaways, with cheap flights from across the UK. Brno and Cesky Krumlov are popular add-ons for those who want a mix of city life and fairy-tale scenery. Many UK networks now charge extra for roaming in the EU, so a local data eSIM can be cheaper and simpler than paying daily roaming fees. You can stay connected without worrying about a surprise bill when you get home.
Indian travellers come for holidays and as students. Prague is a common stop on European tours, and the Czech Republic has a growing number of Indian students at its universities. Whether you are visiting for a week or staying for a semester, you need reliable data for maps, messaging, and staying in touch with home. An eSIM lets you keep your Indian SIM active for bank OTPs and family calls, while using local data for everything else. It is a practical way to avoid expensive international roaming.
| Data | Duration | What it covers |
|---|---|---|
| 1GB | 3-5 days | Maps, WhatsApp text, light email. No video. |
| 3GB | 1 week | Maps, WhatsApp calls, occasional social media. |
| 5GB | 2 weeks | Maps, WhatsApp video, some music streaming. |
| 10GB | 1 month | Daily use including video and video calls. |
For a short city break, 1GB is enough if you stick to maps and messaging. If you are staying longer or plan to share photos and make video calls, go for 3GB or 5GB. You can always top up online on the same eSIM if you run out.
Prague is compact, but public transport tickets and ride-hailing are easiest by app. The city centre is walkable, but you will likely use trams or the metro at some point. Ticket machines can be confusing, and many now accept contactless cards, but the smoothest way is often through a mobile app. Ride-hailing services like Bolt and Uber also work well in Prague and Brno, and you book them through their apps. With a data eSIM, you can download these apps and use them without relying on Wi-Fi.
Many UK networks now charge extra for roaming in the EU. Since Brexit, some UK providers have reintroduced roaming fees for EU countries, including the Czech Republic. These can be daily charges or a set fee for a bundle of data. Before you travel, check your network's policy. A Slashtel eSIM is a simple alternative: you pay once for a set amount of data, and there are no daily charges or surprise costs.
Install your eSIM before you fly, while you are still on home Wi-Fi. The QR code arrives by email within a minute of purchase. Follow our installation guide for step-by-step instructions on iPhone and Android. Your home SIM stays in your phone for calls and OTPs, so you can still receive bank codes and calls from family. If you are an Indian traveller, see our guide on keeping your Indian SIM active abroad.

For most trips a 5GB to 10GB data eSIM valid for 30 days is the right size: Slashtel's 5GB plan for Czechia is $5.69 on Vodafone, O2 and T-Mobile. Install it before you fly, keep your home SIM on for calls and bank texts, and top up the same eSIM if you run low.
If your phone supports eSIM, an eSIM is simpler than a local SIM card: nothing to collect at the airport, no passport registration, and your home SIM stays in the phone for calls and OTP texts. A physical SIM only makes sense for long stays where you need a local phone number.
