Frequently Asked Questions
What is the cheapest eSIM for Saint Lucia?
Saint Lucia is covered by multi-country plans only, and the cheapest is $5.49 for 1 GB, valid for 7 days. Prices come live from 5 vetted providers and change often; the price on this page is the current one.
Is it worth getting an eSIM for Saint Lucia?
For most tourists and business travellers, yes, if your phone supports eSIM. Saint Lucia plans start at $5.49 for 1 GB, and you install the eSIM before you fly, so you have data when you land, without queuing for a tourist SIM at the airport. If your home plan already covers Saint Lucia at no extra cost, you may not need one.
Which networks do Saint Lucia eSIMs use?
Saint Lucia eSIMs on MobiMatter run on 2 networks: Digicel and Flow. Each plan names its network, so you can pick the one with better coverage where you are going.
Which eSIM is best for Saint Lucia?
No plan covers Saint Lucia alone right now, so the choice is a multi-country plan. The top one is 5 GB for 30 days at $22.99 from NextLink, covering 37 countries. We rank plans on quality and value for money. If price per GB is all that matters, the lowest right now is $2.80 per GB, with 25 GB for 90 days.
How much data do I need for a week in Saint Lucia?
It depends on how you use your phone. Light use (maps, messaging, browsing) takes about 0.5–1 GB a day; scrolling a lot of social video can take 2–3 GB or more. Typical use per hour:
- Instagram Reels, TikTok: 0.3–1 GB
- YouTube, Netflix at standard quality: 0.5–1 GB
- Video calls (WhatsApp, FaceTime): 0.5–1 GB
- Voice calls (WhatsApp, FaceTime Audio): 50–70 MB
- Maps and navigation: 2–6 MB
- Messaging and browsing: 50–150 MB
The cheapest Saint Lucia plan with at least 5 GB for a week or longer is 5 GB for 30 days at $21.99.
Do Saint Lucia eSIMs support 5G and hotspot?
Saint Lucia plans currently run on 4G/LTE. Hotspot (tethering) works on every plan, so you can share your data with other devices.
Does a Saint Lucia eSIM come with a phone number?
Most travel eSIMs, including most Saint Lucia plans, are data-only and have no local number. You keep your usual number on your main SIM for calls, texts and WhatsApp. Plans that include a number or minutes say so on the plan page.
Will my phone work with a Saint Lucia eSIM?
Yes, if it supports eSIM and is not locked to a carrier. To check, dial *#06#: if an EID number appears, your phone supports eSIM. Most iPhones from the XS/XR on, Galaxy S20 and later and Pixel 3 and later do, except most models sold in mainland China and some sold in Hong Kong and Macao.
Can I keep my own SIM and WhatsApp while using a Saint Lucia eSIM?
Yes. Your eSIM and your main SIM can be active at the same time. Use the eSIM for mobile data with data roaming on for that line, and turn data roaming off on your home SIM to avoid charges. WhatsApp keeps working on your usual number.

I used it for the first time with my wife during our trip to Japan and Korea, and I didn't experience any connection problems. The internet was fast enough in both Japan and Korea, and I was satisfied with the app. I recommend it.

I used it in Italy in 2024 and in Spain in 2026, and I was very satisfied. The app has improved day by day, and I never experienced any issues. I don't know about other apps, but I highly recommend MobiMatter. I bought 15GB of internet in Spain, and even though I didn't use that much, I still have 10GB left.

"I think this is the fourth time I'm using it abroad. There was only one issue, but the support was very quick. It feels like they are waiting at the screen for fast help. The problem was identified in seconds and a new QR code was sent. Thank you very much."

Awesome service. I have traveled back-and-forth between the United States and the Philippines and this app has not let me down. I strongly suggest that you check your data roaming option so this way you don’t mess up what you need to do.
