Antigua and Barbuda travel data eSIM
What is an Antigua and Barbuda eSIM?
Arriving in St. John’s or exploring English Harbour, you need immediate data access. A CometSIM eSIM installs via QR code before departure, ensuring your phone is ready upon landing. The plan activates only when you first connect to a local network in Antigua and Barbuda. This setup lets you navigate the Central Plain, check ferry schedules, or share photos from Codrington Lagoon without searching for Wi-Fi or dealing with roaming charges from your home carrier.
Your data connects to FLOW 4G networks. This single operator structure means your connection relies on their infrastructure in Antigua and Barbuda. Whether you are in the Shekerley Mountains or the flatlands near All Saints, the eSIM routes traffic through this provider. Coverage availability depends entirely on FLOW 4G’s presence at your specific location, so check local network maps before relying on data in remote areas.
Local networks
Which networks you connect to in Antigua and Barbuda
Your eSIM connects to FLOW 4G, the primary operator listed for this plan. When you arrive, your device links to their 4G infrastructure. Actual coverage depends on where FLOW 4G operates within Antigua and Barbuda. You may find connectivity in urban centers like St. John’s or Bolans, but availability varies by specific spot. Always verify current network status in your area to ensure your data plan functions as expected during your stay.
5 plans are available for Antigua and Barbuda, from $13.90 up to $174.90. Every plan is data only, delivered by QR code, and starts counting when you connect on arrival.

Questions people actually ask
If yours is not here, write to us — we answer within 24 hours.
Which operator does the Antigua and Barbuda eSIM use?
The plan connects to FLOW 4G. This means your data traffic routes through their network infrastructure. Your experience depends on FLOW 4G’s availability in your specific location within the country, so check local network presence before traveling to remote spots.
Does this eSIM work in neighbouring countries?
No, this is a single-country plan valid only in Antigua and Barbuda. It does not work in neighbouring regions like Anguilla or Saint Kitts and Nevis. For multi-country trips, look for regional plans that include multiple destinations in the Caribbean area.
Which plan size suits a trip to St. John’s and Codrington?
As a rough guide, a 3GB or 5GB plan often fits a short visit to these two areas. Heavier data use for streaming or constant map navigation might require the 10GB option. Assess your typical daily usage to choose the appropriate size.
Will I lose my own phone number?
No. Your physical SIM stays in the phone and keeps your number for calls and WhatsApp. The eSIM only carries data, so both work side by side.
When does my plan start counting down?
When the eSIM first connects to a network at your destination — not when you buy it. So you can install it days before you fly without losing any time.
Is my phone compatible?
Most phones from 2018 onwards are: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. Your phone also has to be carrier-unlocked. Dial *#06# — if an EID appears, you have eSIM. Full list on our Device Compatibility page.
How fast will I get my QR code?
Usually within a couple of minutes of payment, by email. If it has not arrived, check spam first, then write to us and we will resend it immediately.
Can I use hotspot or tethering?
Yes, on every plan we sell. Share the connection with a laptop, a tablet or the rest of your group.
What if I change my mind?
If you have not installed the eSIM, you get a full refund within 180 days. Once a profile is activated and data has been used it cannot be refunded — the allowance is consumed from the network. Full detail in our Refund Policy.
Do you sell plans for groups?
Yes. For Umrah and Hajj groups, student trips and tour operators we deliver the QR codes as a single batch before departure, at group rates. Email us with your group size and destination.
