Questions people ask about a Saint Barthélemy eSIM
What is the best eSIM for Saint Barthélemy?
The one that fits your trip and runs on Saint Barthélemy’s main networks (Orange). For a week most people need about 3 GB; for two weeks about 5 GB; for a month of social and video, 10 GB or more. NUM lists 8 plans here and picks one for your trip and how you use your phone.
How much does an eSIM for Saint Barthélemy cost?
On 4 Nov 2026, plans started at $1.09 and went up to $72.59 for the biggest. NUM’s 7-day pick was 3 GB for $2.99, the 14-day pick 5 GB for $4.39 and the 30-day pick 10 GB for $6.39. The shop always shows today’s price, and the price on the pay button is the price you pay.
How much data do I need for Saint Barthélemy?
As an estimate: maps and messages use about 0.2 GB a day, adding social feeds about 0.4 GB, and video calls or streaming 1.5 GB or more. So a week of everyday use is about 3 GB, two weeks about 5 GB, and a month 10 GB or more.
Is there an unlimited eSIM for Saint Barthélemy?
Not on 4 Nov 2026. The plans for Saint Barthélemy have a set amount of data; you can add more to the same eSIM from your order page if you run low.
Is an eSIM better than roaming in Saint Barthélemy?
For data, usually yes: a travel eSIM is prepaid, so there is no bill afterwards, and you choose the amount before you go. Your home carrier’s roaming can still be handy for calls and texts; keep your home line on for those and turn its data roaming off.
Should I get a local SIM card in Saint Barthélemy instead?
A local SIM can give you a local number, but you queue for it after you land and swap out your home SIM. An eSIM installs before you fly, works as the plane lands, and leaves your home SIM in place for calls and bank codes.
Does a Saint Barthélemy eSIM work everywhere in the country?
It works wherever Saint Barthélemy’s networks (Orange) reach. Cities and main roads are well covered; remote islands, mountains and parks can have weak or no signal, so download offline maps before you go.
Will my Saint Barthélemy eSIM work in neighbouring countries?
A Saint Barthélemy plan works in Saint Barthélemy only. For several countries, a North America regional plan covers them on one eSIM; each plan lists the countries it covers.
When do the days start counting?
Install it at home on wifi; switch the line on when you land. Each plan in the shop says when its validity starts, so check that before you pay if you are installing well ahead.
Can I use it as a hotspot?
Hotspot works on most plans, so one eSIM can get a laptop or a travel partner online too.
Which network works well in Saint Barthélemy?
Orange switched on 5G in Saint-Jean and Gustavia in 2023. One coverage aggregator lists Orange's top-quality 4G over a smaller share of the island than rivals SFR and Bouygues, so reception may vary by spot.
Why does my eSIM show another carrier’s name?
Many travel eSIMs are issued by one carrier and roam on local networks, so your phone can show the issuing carrier’s name while your data runs on a local network. Keep data roaming on for the eSIM.
Will it work on my phone?
Dial *#06# on the phone you’re taking. If you see an EID number, it takes an eSIM. Every iPhone from the XR and XS on does, and the SE from 2020, as do Google Pixel 3 and later and Samsung Galaxy S20 and later. The phone must be carrier-unlocked. Not sure? Text PHONE and your model and we’ll check.
When do I install it?
At home, on wifi, before you fly. Then switch it on when you land. Tell us your landing day and we text you the switch-on steps that morning.
Does it come with a phone number?
No. It’s a data-only eSIM. WhatsApp, LINE, iMessage and FaceTime all work over it, and your home number can stay on for calls and codes.
What if it doesn’t work?
If we can’t issue your eSIM, we refund you in full. If it won’t install or connect, text us and we help you get connected.
