Compare Gibraltar eSIM plans for Main Street and Casemates Square, the Upper Rock Nature Reserve, Europa Point and Catalan Bay. Gibraltar is small enough to cross on foot, so the real data question is what happens when the day continues into Spain.
Gibraltar is a British Overseas Territory of under seven square kilometres at the southern tip of the Iberian Peninsula, where the Rock rises to 426 metres above the Strait. The town fills the western slope, and the airport runway crosses the narrow isthmus between the town and the land frontier with La Línea de la Concepción in Spain. Many visitors walk across that frontier on a day trip from the Costa del Sol; others arrive by cruise ship or on direct flights from the United Kingdom. On clear days, the mountains of Morocco are visible across the water.

Install the Gibraltar profile at home over Wi-Fi and keep the order details in a second place. If you are driving or taking a bus down from Málaga or another Spanish airport, remember that Spain is a different territory: either arrange data for that part of the journey or keep the Gibraltar line off until you have crossed the frontier. Once in Gibraltar, switch the travel line on, choose it for mobile data and enable data roaming for that line. The validity period does not begin at installation: it begins when the eSIM first connects to a supported network in Gibraltar. Save cable car times and tunnel tour details offline beforehand.

Pick the profile closest to your trip. The estimate assumes normal use — maps, messaging, photos, a short call home.
As a rule of thumb, a 3–4 day city break runs on about 1–3 GB, a one-week trip on 3–5 GB, a two-week multi-country tour on 8–12 GB, and working on the road takes about 1 GB a day, so 15 GB or more for two weeks.
In total, a 10 GB data allowance covers roughly 3,300 shared photos, 167 hours of social media and browsing, 29 hours of video calls, 125 hours of music streaming, or about 2000 hours of maps and navigation. Messaging apps barely use data.
Main Street · City guide
Main Street runs the length of the old town, from Casemates Square, a former barracks square now lined with cafes, south towards the Convent, the Governor's residence, where a ceremonial guard is mounted outside. Along the way are the Gibraltar National Museum, which includes well-preserved Moorish baths, the Anglican and Catholic cathedrals and a long run of shops. It is all walkable, and most visitors spend part of every day here. Bus stops and the cable car's lower station are close by, so save the times you need before setting off.
Main Street eSIM — set up before you flyUpper Rock · City guide
The Upper Rock Nature Reserve covers the top of the Rock and holds most of its sights: the Barbary macaques, Europe's only wild monkey population, St Michael's Cave with its concert auditorium, the Great Siege Tunnels dug by hand in the eighteenth century, the Moorish Castle and the Skywalk viewing platform. The cable car, minibus tours and steep footpaths all lead up. The macaques snatch bags and phones, and feeding them is prohibited, so keep belongings closed. Inside the tunnels and caves, expect to be offline.
Upper Rock eSIM — set up before you flyEuropa Point · City guide
Europa Point is the southern tip of Gibraltar, where the lighthouse, the Ibrahim-al-Ibrahim Mosque and the Shrine of Our Lady of Europe stand within a short walk of each other. On clear days the coast of Morocco is plain across the Strait, and the cliffs drop straight into busy shipping lanes. Buses run here from the town centre, and the walk back along the coast road is long but straightforward. Wind can be strong on this exposed point, so check the weather and save the return bus times first.

Catalan Bay is a small former fishing village on the eastern side of the Rock, with a sandy beach, colourful houses and the Rock's sheer east face rising behind it. Eastern Beach, further north near the airport, is the longest stretch of sand, and Sandy Bay lies to the south. The east side is reached by road from the north end of town, and the sea here is exposed to the Levante wind, which can bring waves and a cloud cap over the summit. Check conditions and keep the bus route saved.

Gibraltar itself can be walked end to end in an afternoon, so the size of the territory rarely limits a trip. What matters is the border: many visitors sleep in Spain, arrive through Málaga, or combine Gibraltar with Tarifa, Seville or a ferry to Morocco from Algeciras. Count the days you will actually spend in Gibraltar, then read the destination list on the offer and decide whether Spain needs a separate plan or an offer that names both. Gibraltar is outside the EU, so check how your home contract treats it too.

Yes, unless the offer you choose names both territories. Gibraltar and Spain are separate destinations, and a plan written for Gibraltar stops at the frontier, even though La Línea de la Concepción is only a few minutes' walk away. If you are staying in Spain and visiting Gibraltar for a day, a plan for Spain plus a separate one for Gibraltar, or an offer that lists both, is the clean arrangement. Read the destination list before the frontier day rather than at the barrier.
Not necessarily. Gibraltar left the European Union together with the United Kingdom, so EU roaming rules do not automatically apply there, and many EU contracts treat it as outside their roaming zone. UK contracts vary as well. Check your home provider's current terms for Gibraltar before travelling. If you rely on a travel eSIM instead, leave the home line's data switched off so it does not run up charges while the travel line carries your data.
There are three usual ways. The cable car runs from its lower station near the Alameda Gardens to the top station, though it can close in high winds. Minibus and taxi tours drive up through the nature reserve and stop at the main sights, and walkers can climb by road or by steep paths such as the Mediterranean Steps, which suit only the sure-footed. Tickets for the reserve's attractions are needed in any case. Save the cable car times and the tour meeting point before you start the climb.
A day covers the highlights: Main Street, the Upper Rock with the macaques, St Michael's Cave, the Great Siege Tunnels and Europa Point. An overnight adds a slower look at the tunnels and museums, an evening in Ocean Village or Casemates, and an early start on the Rock before the day visitors arrive. Accommodation is limited and in demand, so many people stay in Spain. Whichever you choose, the border crossing is the step to plan, together with the data for each side.
They can be. The macaques are wild, used to people and quick to grab anything that looks like food, including bags, bottles and loose phones. Keep belongings zipped, do not eat near them and never feed them, which is prohibited and can lead to a fine. Taking photos from a sensible distance is no problem. If a macaque does take something, do not try to wrestle it back; ask a nearby guide or warden for help, and keep the phone on a strap or in a pocket while on the Upper Rock.
On clear days the Moroccan coast is easy to see from Europa Point and the top of the Rock. Reaching it is another matter: most ferries across the Strait leave from Algeciras and Tarifa on the Spanish side, and the crossing takes you into another country with its own entry rules. A plan written for Gibraltar does not include Spain or Morocco, so for a day in Tangier or a longer onward trip, check the destination list and arrange a plan for each country on the route.
Tunnels and caves inside the Rock block a mobile signal almost entirely, so being offline there is expected. Near the frontier and around the bay, a handset may also pick up networks from the Spanish side, and the plan covers only the territory its offer names. If data fails in the open, check that the travel line is on, selected for mobile data and has data roaming enabled, and see which network the phone has joined. Save tickets, maps and meeting points offline before going underground.
No. Horizon fixed-data plans have no throttling. There is no daily limit that slows you down, so you can use your whole plan in one day if you need to. Your speed depends on the local network, your signal and how busy the network is. When your data allowance is used up, the plan stops rather than slowing down.
Yes. We always refund the full amount you paid when you request it, whether your eSIM is unused, partly used or fully used. There is no time limit for requesting a refund.
