Your plan depends on how long you stay and how much you use. - **A city break in St John's:** Three days of standard use, with maps, messages and a few social posts, suits 3 GB for 15 days. - **A fortnight touring the island:** For 14 days of standard use, pick 10 GB for 30 days, which leaves room for music and some video. - **A business trip:** Seven days of heavy use, with streaming and a hotspot for your laptop, suits 2 GB a day for 7 days. - **A Caribbean hop:** If your trip takes in other islands, the Caribbean bundle covers 25 countries, so check [Caribbean eSIMs](/esim/caribbean). Most plans can be topped up, and the longest plan runs for 30 days. ## Will my eSIM have signal in Antigua & Barbuda? FLOW is the network your eSIM joins in Antigua & Barbuda. Your phone finds it on its own, so there's nothing to pick. Land, switch on, and you're online. Your eSIM runs on 4G. Your data reaches the internet through Europe, which is a normal setup for travel eSIMs. To see what that means for your browsing, read [your IP address in another country](/help/ip-address-another-country). Daily plans slow down to a lower fair-use speed once the day's allowance is used up, so pick a size that covers your busiest day. ## Using your phone in Antigua & Barbuda: data tips - **Install at home:** Add your eSIM over Wi-Fi before you fly, so you won't be hunting for a signal at V.C. Bird (ANU). - **On arrival:** Once you've landed, switch your eSIM line on, [turn on data roaming](/help/turn-on-data-roaming) for it, and then open your maps. - **Getting around:** Your eSIM uses the FLOW network in St John's, English Harbour, Jolly Harbour, Dickenson Bay and Barbuda, so keep your maps on as you explore. - **Staying in touch:** Message people on [WhatsApp](/help/keep-whatsapp-and-home-number) over your eSIM data, while your home number stays on for calls and texts. Keep it simple: your eSIM line is for data, and your home line is for calls. - **Good to know:** Plans run up to 30 days, and most can be topped up, so you can add more data mid-trip. After your daily allowance, speeds drop to 512 Kbps. ## Questions ### How much is an eSIM for Antigua & Barbuda? Antigua & Barbuda eSIMs start at £8.99 for 500 MB a day over 1 day.
