Common Questions

What you need to know about your Caribbean eSIM

A Caribbean eSIM is a multi-country digital SIM covering destinations across Caribbean. Rather than buying a different local SIM for each country, you scan one QR code before you go and your data plan works across every covered destination — no physical SIM card, no queues at airport kiosks.

Coverage varies by plan tier, but our Caribbean plans cover the most popular destinations in the region. Select a plan in the booking card above, and the exact country list appears on the plan detail page. Check your specific destinations before buying.

Yes. Install the eSIM at home over Wi-Fi, set it as your data SIM, and the plan starts automatically when your phone finds a supported local network. No setup needed on arrival. The validity clock begins at first use, not at purchase.

Correct. This eSIM carries data only. Your regular SIM stays in the slot and keeps working — you can still take calls and texts on your home number while the eSIM handles data. Dual-SIM in practice.

The eSIM won't connect there. Your phone either switches to your physical SIM or shows no data connection. For trips that cross several regions, look at our Global eSIM — it reaches 150+ countries worldwide.

Yes. The plan roams across every country in the zone. Cross a border and your phone picks up the local network automatically — no need to tweak settings or restart.

Coverage follows whichever local networks our plan uses. In big cities and tourist spots you'll usually get strong 4G. Further out, signal may drop to 3G or be patchy. If you're heading somewhere remote, it's worth checking the local carrier's coverage map for those specific places.

Tethering works with most regional plans — you can share data with a laptop or tablet via your personal hotspot. Unlimited plans may still apply a fair-use speed cap on tethered traffic. Check the plan details before you buy if hotspot use is important.

Plans run from 1 day up to 30 days. Pick the length that fits your trip. Validity starts the moment you first connect to a network in a covered country — so you can install it before you leave without burning any days.

Yes. If you use up your data or need more time, just buy a new plan from your Onetel account. Your eSIM profile stays in place — add the new plan and it activates immediately.

An eSIM (embedded SIM) is a programmable chip built into your phone. Instead of swapping a plastic card, you download a carrier profile over the air. That means instant activation, no tiny parts to lose, and the ability to keep several plans ready at once on a dual-SIM device.

Any phone launched after 2018 with eSIM support: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later, plus many other Android flagships. The handset must be carrier-unlocked. Check Settings → Mobile / Cellular — if you see "Add eSIM" or "Add Data Plan", you're good to go.

Open Settings → Mobile / Cellular → Add Plan (the wording varies by OS), then scan the QR code we email you. It takes under 2 minutes and needs Wi-Fi or an existing data connection. Install it at home before you leave — that's the smoothest route.

No. The eSIM lives as a separate profile next to your physical SIM. On most dual-SIM phones you pick the eSIM for data and keep your physical SIM for calls and texts. You can store several eSIM profiles and swap between them whenever you like.

Yes, and we advise it. Install the eSIM at home, set it as your travel data SIM, and you're online as soon as you land — no hunting for airport Wi-Fi. The validity clock starts only when the eSIM connects to a network in a covered country, so installing early costs nothing.

Most plans give you 4G LTE as a baseline. 5G works on compatible devices in supported countries where our carrier partners have rolled out 5G. Real-world speeds depend on local network congestion and your phone's radio capabilities.

Onetel eSIM plans carry data only. For voice calls and texts, use apps like WhatsApp, FaceTime, iMessage, or Signal over your mobile data. Your physical SIM still works for traditional calls and texts on your home number.

Your mobile data stops but the eSIM profile remains on your device. Log in to your Onetel account, grab a top-up or new plan, and you\'ll be back online in minutes. The new plan activates automatically on the same eSIM profile.

Yes, with most plans. Unlimited plans may limit hotspot traffic under a fair-use policy. Fixed-data plans normally let you use the full allowance as a hotspot. Check the plan description for specific tethering rules before buying.

Yes. eSIM profiles use the same encryption as physical SIMs. The profile is tied to your phone\'s unique identifier (EID) and cannot be moved or copied. If you lose the phone, the eSIM is as secure as the lock screen.

Onetel brings together data plans from multiple carrier partners, so you can compare and pick the best rate for each stop on your trip. No contracts, no paperwork — the eSIM lands in your inbox within minutes, ready to install before you board.

Yes. Payments run through industry-standard TLS encryption, and we accept Visa, Mastercard, PayPal, Apple Pay and Google Pay. We never store full card details. Thousands of travellers rely on Onetel for dependable connectivity on every trip.

The QR code arrives instantly — usually within 10 seconds of payment. It lands in your inbox and also appears in your Onetel account dashboard. If it's not there, check your spam folder or contact our support team.

Request a full refund within 30 days as long as the QR code hasn't been scanned and the eSIM hasn't been installed or activated. Once installed or activated, the eSIM is non-refundable even if you haven't used any data. Contact support with your order number.

Yes. Increase the quantity during checkout. Each traveller receives their own QR code to the same email address. For groups, ask us about a bulk pricing quote.

No. Every Onetel travel eSIM is a one-off purchase — no subscriptions, no auto-renewals, no hidden fees. You choose what to buy and when, with full control at every step.

Our team is here 24/7 through live chat (the icon at the bottom-right of every page) and by email. We usually reply to live chat messages within 2 minutes and to emails within a few hours. For urgent activation help, live chat is the quickest option.

Yes. A detailed VAT invoice is emailed after purchase — with your name, the plan bought, and the amount paid. Ready for any expense report.

Corporate accounts with consolidated billing and an admin dashboard are in development. For now, frequent travellers can save payment details for faster top-ups and view full order history from their account dashboard.

Our support team handles queries in English, with extra help available through translation tools for other languages. We're expanding multilingual support — tell us which language you need and we'll do our best.
