How does a multi-country bundle eSIM work?

A bundle eSIM gives you a single data pool that works across all countries in the bundle. When you cross a border, your phone automatically connects to the local network — no SIM swap, no roaming fees.

Common Questions

Everything worth knowing about your China, Hong Kong, Indonesia + 9 More eSIM

The China, Hong Kong, Indonesia + 9 More eSIM is one data plan that covers 12 countries on one digital SIM. Scan a single QR code before you leave and the same plan follows you from border to border. No local SIM to buy in each country, no plastic card, no waiting at an airport kiosk when you would rather be gone.

This bundle works in 12 countries, all drawing from the same data pool. Cross a border and the eSIM picks up the local network on its own — no settings to change, no reboot.

No. A single shared data allowance covers all 12 countries. Pay once, then your balance and plan validity travel with you to every country in the bundle.

Yes. Install it at home on Wi-Fi and set it as your data line. The plan begins the first time your phone connects to a supported network abroad. The validity clock runs from first use, not from the day you paid.

Yes. It is a data-only profile, so your physical SIM stays in the phone and stays live. Calls and texts keep arriving on your home number while the eSIM does the data. That is what dual SIM is for.

Outside the bundle, the eSIM will not connect. Your phone falls back to the physical SIM or shows no data at all. Want wider coverage? Our Global eSIM runs across 150+ countries worldwide.

Personal hotspot works on most bundle plans. Fixed-data plans usually let the whole allowance be shared. Unlimited plans may put a fair-use speed cap on tethered traffic. If hotspot matters to you, read the plan specifics before you pay.

Yes. Once the allowance is gone, buy another plan from your Onetel account. The eSIM profile stays on the phone — add the new plan and it activates instantly.

Fixed GB plans stop once the allowance is used. Unlimited plans keep going, though very heavy use can trigger a fair-use speed reduction. Either way, you can add a new plan whenever you want.

Yes. An unactivated eSIM gets a full refund, any time within 30 days of purchase, no questions asked. Send support your order number and we will process it promptly.

An eSIM is a programmable chip already soldered inside the phone — embedded SIM. The carrier profile arrives over the air instead of on a plastic card you have to swap out. So activation is instant, there is no tiny part to lose, and a dual-SIM device can hold several plans at once.

If your phone launched after 2018, it very likely works: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later, plus a wide range of other Android flagships. The handset must be carrier-unlocked. Quick check: open your settings under Mobile / Cellular and look for "Add eSIM" or "Add Data Plan". If it is there, you are compatible.

Open Settings → Mobile / Cellular → Add Plan — the exact wording depends on your OS — then scan the QR code from the email we send. It takes under 2 minutes and needs Wi-Fi or an existing data connection, which is why doing it at home before the trip is easiest.

No. Nothing gets removed. The eSIM lives as its own profile beside the physical card. On most dual-SIM phones you point data at the eSIM and leave calls and texts on the physical SIM. Keep several eSIM profiles stored and switch between them whenever you like.

Yes, and it is the better way to do it. Set it up at home, mark it as your travel data SIM, and you are online the moment the plane doors open. No hunting for airport Wi-Fi. The validity clock only starts when the eSIM connects to a network in a covered country.

4G LTE is the floor on most plans. Where the country supports it and your handset can take it, you get 5G. Real speed depends on how busy the local network is and what your phone radio can do.

Onetel eSIM plans carry data only. Make calls and send messages through apps like WhatsApp, FaceTime, iMessage or Signal over that data. Ordinary calls and texts still reach your home number, because the physical SIM stays active.

Data stops, but the eSIM profile stays installed. Just log in to your Onetel account, buy a top-up or a fresh plan, and you are back online within minutes.

On most plans, yes. Fixed-data plans generally let the full allowance run through a hotspot. Unlimited plans may apply a fair-use cap on hotspot traffic. The plan description sets out the tethering rules — read it before you buy.

Yes. eSIM profiles run on the same encryption standards as physical SIMs. Each profile is locked to your device unique identifier (EID), so it cannot be cloned or moved to another phone.

Onetel is a global eSIM marketplace. We pull plans from several carrier partners and show you the best price for each destination rather than one carrier's rate card. The point is straightforward: buying mobile data abroad should take about as long as buying a coffee. No contracts, no paperwork, instant delivery.

Yes. Payments run over industry-standard TLS encryption, and we take Visa, Mastercard, PayPal, Apple Pay and Google Pay. Full card details are never stored on our side. Every month, thousands of travellers rely on Onetel to stay connected without the hassle.

The QR code is instant — usually inside 10 seconds of payment confirmation. It hits your inbox, and a copy sits in your Onetel account page.

Activation failed, or you used no data at all? Ask for a full refund up to 30 days after purchase. Give our support team your order number and we will process it promptly.

Yes. Raise the quantity at checkout. Everyone gets their own unique QR code, all delivered to the same email address.

No. Every Onetel travel eSIM is bought once. No subscription, no renewal running quietly in the background, no surprise charges.

Live chat and email, 24/7. Chat messages get a reply within 2 minutes; emails within a few hours.

Yes. A detailed VAT invoice arrives by email after purchase, with everything an expense claim needs.

Business accounts with consolidated billing and admin dashboards are in the works. Until then, frequent flyers can store payment details in their account and re-purchase faster.
