Frequently Asked Questions

Everything you need to know about your Caribbean eSIM

A Caribbean eSIM is a multi-country digital SIM that covers destinations across Caribbean. Instead of buying a separate local SIM in each country, you scan one QR code before you travel and your data plan follows you across every covered destination — no physical SIM, no airport kiosk queues.

Coverage varies by plan tier, but our Caribbean plans are designed to cover the most popular travel destinations in the region. When you select a plan in the booking card above, the exact list of covered countries is shown on the plan detail page. We recommend verifying your specific destinations before purchase.

Yes. Install the eSIM at home over Wi-Fi, set it as your data SIM, and the moment your phone connects to a supported local network the plan begins. No configuration is needed on arrival. The validity countdown starts from first use, not from purchase.

Absolutely. The eSIM is a data-only profile. Your physical SIM stays installed and fully active — you can still receive calls and texts on your home number while using the eSIM for data. Dual SIM at its best.

The eSIM simply will not connect in uncovered countries. Your phone will fall back to your physical SIM or show no data. If you plan a trip that spans multiple regions, consider our Global eSIM instead — it covers 150+ countries worldwide.

Yes. The plan roams seamlessly between all covered countries. Cross a border and your connection switches automatically to the local network — no settings change, no reboot required.

Coverage depends on the local carrier networks our plans roam onto. In major cities and tourist areas coverage is typically excellent. Remote or rural areas may have limited 4G and fall back to 3G. We recommend checking carrier coverage maps for your specific destinations if you plan extended off-the-beaten-path travel.

Most of our regional plans support personal hotspot so you can share your data with a laptop or tablet. Unlimited plans may apply a fair-use speed cap on tethered traffic. Always check the plan specifics before purchase if tethering is essential for you.

We offer plans from 1 day up to 30 days. Choose the duration that matches your itinerary. The validity period begins when the plan is first activated on a network in a covered country — so you can install it in advance without "wasting" any days.

Yes. If you exhaust your data or need more days, you can purchase a new plan from your uPhone account. Your eSIM profile stays installed — just add the new plan and it activates instantly.

An eSIM (embedded SIM) is a programmable chip soldered directly into your phone. Instead of physically swapping a plastic card, you download a carrier profile wirelessly. The result is instant activation, no small parts to lose, and the ability to hold multiple plans simultaneously on a dual-SIM device.

Most modern smartphones launched after 2018 support eSIM: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later, and a wide range of other Android flagships. Your device must be carrier-unlocked. Check your phone's settings under Mobile / Cellular — if you see "Add eSIM" or "Add Data Plan", you're compatible.

Go to Settings → Mobile / Cellular → Add Plan (wording varies by OS), then scan the QR code we email you. The process takes under 2 minutes and requires a Wi-Fi or existing data connection. We recommend doing this at home before your trip for the smoothest experience.

No. The eSIM is a separate profile stored alongside your physical SIM. On most dual-SIM phones you simply assign the eSIM for data and keep your physical SIM active for calls and texts. You can have multiple eSIM profiles stored and switch between them at any time.

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

Most plans deliver 4G LTE as a minimum. 5G is available on compatible devices in supported countries where our carrier partners have deployed 5G infrastructure. Actual speeds depend on local network congestion and your device's radio capabilities.

uPhone eSIM plans are data-only. For calls and messages use apps such as WhatsApp, FaceTime, iMessage, or Signal over your data connection. Your physical SIM remains active for traditional calls and texts on your home number.

Your data connection will stop but your eSIM profile stays installed. Simply log in to your uPhone account, purchase a top-up or a new plan, and you'll be back online within minutes. The new plan activates automatically on the same eSIM profile.

Yes, on most plans. Unlimited plans may apply a fair-use cap on hotspot traffic. Fixed-data plans typically allow the full allowance to be used as a hotspot. Check the plan description for specific tethering details before purchasing.

Yes. eSIM profiles use the same encryption standards as physical SIMs. The profile is locked to your device's unique identifier (EID) and cannot be transferred or cloned. If you lose your phone, the eSIM is as protected as your phone's lock screen.

uPhone is a global eSIM marketplace that aggregates plans from multiple carrier partners so you always get the best price for every destination. We're a travel-tech company focused on making mobile data abroad as simple as buying a coffee — no contracts, no paperwork, instant delivery.

Absolutely. We process payments over industry-standard TLS encryption and accept Visa, Mastercard, PayPal, Apple Pay, and Google Pay. We never store full card details. Thousands of travellers trust uPhone for hassle-free connectivity every month.

QR code delivery is instant — typically within 10 seconds of payment confirmation. It arrives in your inbox and is also available in your uPhone account dashboard. If you don't see it, check your spam folder or reach out to our support team.

If your eSIM fails to activate or you haven't used any data, you can request a full refund within 30 days of purchase. Contact our support team with your order number and we'll process it promptly — usually within one business day. Plans that have been activated and used are non-refundable.

Yes. During checkout you can increase the quantity. Each traveller gets their own unique QR code delivered to the same email address. For large groups, contact us for a group pricing quote.

No. Every uPhone travel eSIM is a one-time purchase. There are no subscriptions, no hidden renewals, and no surprise charges. You are always in full control of what you buy and when.

Our team is available 24/7 via live chat (the icon in the bottom-right corner of every page) and by email. We aim to respond to live chat messages within 2 minutes and emails within a few hours. For urgent activation issues, live chat is the fastest route.

Yes. After purchase you receive a detailed VAT invoice by email. The invoice includes your name, the plan purchased, and the amount paid — everything you need for an expense claim.

We're working on business accounts with consolidated billing and admin dashboards. In the meantime, frequent travellers can store payment details in their account for faster re-purchase and access full order history from the dashboard.

Our support team handles queries in English, with assistance available in additional languages via translation tools. We're expanding multilingual support — if you need help in a specific language, let us know and we'll do our best.
