Nextline

A travel eSIM and a second mobile number in one service

Nextline combines travel data eSIM plans with a second phone-number service. The app is designed for people who want mobile data while travelling and a separate number for calls, texts or WhatsApp, without handing out their primary line. It is an online telecommunications service rather than a walk-in mobile shop, so there is no local branch or directions route for visitors.

Choose connectivity for the destination

The purchase flow starts by selecting a destination and then choosing a data plan. The service presents local, regional and global eSIM options, allowing a traveller to compare coverage for one country with plans that span several destinations. This can be helpful when an itinerary crosses borders, but the included countries, data allowance, validity period and network details need to be checked for the exact plan before purchase.

An eSIM is a digital SIM profile installed on a compatible device. Nextline provides setup guidance for checking device support and installing a plan, including QR-code and manual setup instructions. Before travelling, confirm that the phone or tablet supports eSIM, is eligible for the intended network, and can keep the existing SIM active in the way the traveller expects. Coverage and service depend on the selected destination and plan.

Keep a separate number for calls, messages and WhatsApp

Nextline also offers a second number that can be used for calls, texts and an additional WhatsApp account. This can separate travel, work or temporary communications from a personal number. The number service and a data eSIM are related parts of the product, but the available number countries, call and message rules, charges, renewal terms and WhatsApp activation requirements should be reviewed separately. A second number does not guarantee that every app or service will accept it for verification.

Plan the setup before departure

1. Check compatibility: verify eSIM support on the specific device and whether it is unlocked for the networks you intend to use.
2. Compare destinations: choose the local, regional or global data option that matches the itinerary and confirm coverage for each stop.
3. Read the plan terms: check data allowance, validity, number availability, calling and messaging charges, and what happens when a plan expires.
4. Install in advance: follow the QR-code or manual setup guide while internet access is available, then enable the plan at the appropriate time.

The service provides help articles for device compatibility and installation, with customer support available through the contact panel. Because eSIM support and mobile-number regulations vary by device and country, confirming those details before buying is the safest way to avoid arriving without the connectivity you expected.
