You step off the plane at Sir Seewoosagur Ramgoolam International Airport (MRU) into warm, humid air. The queues for local SIMs can be long, and after a long flight you probably want to get to your hotel, not stand in another line. A travel eSIM means you can sort your data before you even leave home, so you land connected.
Slashtel offers a Mauritius eSIM that is data only. No local number, no calls or SMS, but WhatsApp calls work over data. You get a QR code by email within a minute of ordering, and you install it on your phone before you fly. Prices start from $5.39, with no contract and no local address needed. It is a simple way to stay online for maps, messages and sharing photos.
Who goes and why
UK travellers often come to Mauritius for beach holidays and honeymoons. The island is a long haul favourite, with direct flights from London and a mix of luxury resorts and quiet coves. You might spend a week in Grand Baie, then move to the south coast for a quieter stretch. Having data means you can book a taxi, check restaurant reviews or send a photo of the sunset without hunting for Wi Fi.
Indian travellers visit for honeymoons and to see family. Mauritius is a popular wedding destination and also home to a large Indian diaspora, so many trips combine celebration with catching up with relatives. You may land in Port Louis, then drive to relatives in another district. Data keeps you in touch on WhatsApp and helps with navigation when you are borrowing a car or taking a taxi.

Two practical notes for Mauritius
Hire cars are a common way to get around, so offline or live maps matter. Many visitors rent a car to explore at their own pace. With a data eSIM you can use live navigation, but it is wise to download offline maps as a backup. That way, if you hit a patch of weak signal, you can still find your way.
Coverage is good along the coast and can be weaker in the hilly interior. Port Louis, Grand Baie and the south coast resorts generally have strong signal. If you drive through the central plateau or visit Black River Gorges, expect spots where data drops. Download what you need before you set off, and do not rely on streaming in remote areas.
Install before you fly
Install your eSIM at home while you have stable Wi Fi. The QR code arrives by email within a minute, and you can add it to your phone straight away. Leave it switched off until you land, then turn it on and it will connect to a major local network. Your home SIM stays in the phone for calls and OTPs, so you can still receive bank codes and calls from family. For step by step instructions, see our installation guide. If you are keeping an Indian number active, read our guide on keeping your Indian SIM active.
