You are flying to Spain from the UK or India. You have a holiday, an Erasmus semester, or a long winter escape planned. You do not want to land in Madrid or Barcelona and hunt for a SIM card shop while your luggage sits unattended.
A Slashtel Spain eSIM solves that. You buy it online, scan a QR code, and you have data from the moment you switch off airplane mode. It runs on Spain's main mobile networks, so coverage is solid in cities, along the coast and on the islands.
UK residents fly to Spain for long weekends and winter sun. The short flight and two-hour time difference make it easy. You want data for Google Maps, WhatsApp calls home, and booking restaurant tables on the go. You do not want to think about connectivity.
Indian students and professionals based in the UK often visit Spain for city breaks or to meet friends across Europe. If you also keep an Indian SIM for bank OTPs, you can run both SIMs at once, the Slashtel eSIM handles data, your Indian SIM handles SMS.
| Plan | Price | Best for |
|---|---|---|
| 5GB / 30 days | $5.59 | 3-7 day trip: maps, WhatsApp, light social media |
| 10GB / 30 days | $9.79 | 7-14 days, or daily video calls |
| 20GB / 30 days | $14.19 | 2-3 weeks with streaming or work |
| 50GB / 30 days | $32.29 | Long stays, heavy streaming, hotspot use |
A 5GB plan covers a typical week: 30 minutes of maps per day, WhatsApp messages with photos, and occasional Instagram scrolling. If you plan to stream Netflix on the hotel Wi-Fi, you are fine. If you stream on mobile data, step up to 10GB.
Arrival airport data. Madrid-Barajas and Barcelona-El Prat have free Wi-Fi, but it often requires a registration form. Your eSIM activates on landing, so you can skip the airport Wi-Fi queue and go straight to the taxi rank or metro.
Keep your home SIM for OTPs. If you have an Indian SIM, keep it active for banking codes. Your Spain eSIM runs in parallel, so you do not lose access to either. For UK users, your UK SIM can stay in the second slot for calls, while data runs on the eSIM.
Installation takes about two minutes. Buy the plan, scan the QR code, and the eSIM sits ready on your phone. Data starts only when you connect to a Spanish network.

For most UK visitors a 5GB or 10GB Spain eSIM for 30 days is the best fit: 5GB covers a week of maps, WhatsApp and social media, 10GB covers two weeks or daily video calls. Slashtel's 5GB plan is $5.59 and the 10GB plan is $9.79, both installed before you fly and running on Spain's main networks.
Most unlimited travel eSIMs slow you down after a daily allowance. Fixed-data plans are usually better value: a 20GB or 50GB Spain eSIM for 30 days covers streaming and hotspot use at full speed, and you can top up the same eSIM if you run low.
Slashtel's Spain plans start at $2.59 for 1GB. For a real trip the 5GB plan at $5.59 is the best value, and prices are shown live on this page.
Yes. A Slashtel Spain eSIM connects to a local Spanish network when you land, so you pay the flat data rate shown at checkout. Your UK mobile plan is not involved, so there are no roaming fees from your UK provider.
For a 7-day trip with maps, WhatsApp, and occasional social media, 5GB is usually enough. If you plan to stream video or work remotely, choose the 10GB plan. The 5GB Spain eSIM costs $5.59 and lasts 30 days.
Your Indian SIM will still receive SMS on roaming, which covers bank OTPs. Keep it in a second phone or a dual-SIM slot, and use the Slashtel eSIM for data. That way you avoid international roaming data charges from your Indian carrier.
The data starts when your phone first connects to a Spanish network. You can install the eSIM on Wi-Fi before you fly, and it will activate automatically on arrival. There is no need to contact support when you land.
Most recent phones support eSIM, including iPhone XS or newer and most Android flagships from 2020 onwards. Check our compatibility guide for the full list. If your phone does not support eSIM, you may need a physical SIM instead.
Yes. You can use your Spain eSIM as a mobile hotspot for a laptop or tablet. The data comes from your plan allowance, so keep an eye on usage if you are on the 5GB plan.
For most trips a 5GB to 10GB data eSIM valid for 30 days is the right size: Slashtel's 5GB plan for Spain is $5.59 on Orange, Movistar and Vodafone. That is about 39% less than the major eSIM brands charge for 10GB over 30 days (around $16.00, checked September 2026). 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.
From $2.59 for 1GB valid 7 days, as of 9 October 2026. Longer trips: two weeks from $3.79 (3GB), one month from $3.89 (3GB).
For a 10GB, 30-day plan Slashtel charges $9.79, against a typical price of around $16.00 from the major eSIM brands (checked September 2026), about 39% less. Budget sellers can be cheaper still, often with little or no support; Slashtel includes WhatsApp support and top-ups on the same eSIM.
$0.65 per GB on the 50GB plan (30 days, $32.29). Bigger plans usually cost less per GB, so buy the size you expect to use.
Orange, Movistar, Vodafone and Yoigo, with speeds up to 5G where available. The eSIM picks the strongest network automatically.
No. Slashtel eSIMs are data only, with no local number, calls or SMS. WhatsApp and other internet calls work, and your home SIM can stay on for calls and OTP texts.
Validity starts when the eSIM first connects to a network in Spain, not when you buy it, so you can buy and install it before you travel.
