Is 5G available in St Barthelemy?
The spectrum Arcep assigned to the four operators from May 2025 sits in the 900 MHz, 1800 MHz and 2.1 GHz bands, which are used for 2G to 4G service. No 3.5 GHz 5G band has been assigned on the island.
How much data do you need in St Barthelemy?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in St Barthelemy right now:
Are unlimited eSIMs for St Barthelemy really unlimited?
Not always. 15 of the plans above are sold as unlimited. Most unlimited travel plans have a fair use rule. You get full speed for a daily amount, often 1 to 5 GB, then the speed drops to around 1 Mbps until the next day. That is fine for messages and maps but slow for video. If you know how much data you use, a fixed plan with a low price per GB is usually the better deal. That is why we rank by price per GB and not by labels.
eSIM or a local SIM at the airport in St Barthelemy?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter. Data for St Barthelemy starts at $5.99 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your St Barthelemy eSIM
Buy your planYou get a QR code by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Airport and hotel wifi can be weak.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to find the network.
Check the validity clockSome plans start counting at purchase, not at first use. Check before you buy.
Good to know before you land in St Barthelemy
Saint Barthelemy left the EU in 2012 and became an overseas territory, so the EU roam like at home rule does not apply. Many European plans bill it at rest of world rates.
Gustaf III airport is tiny and has no SIM shops. Buy in Gustavia or Saint Jean, or load an eSIM before you fly.
Do not assume your EU plan covers this island just because it is French. Some French operators include it in their overseas zone and others do not, so check your tariff sheet or buy a local SIM.
