Cellesim: Travel eSIM & Data

Cellesim LLC

About this app

Land in a new country and you are already online. No SIM card to find, no roaming bill waiting for you at home.

WHAT CELLESIM DOES
Cellesim is a travel eSIM. You buy a data plan before you fly, install it with one tap, and your phone connects to a local network the moment you land. Your own number stays active on your normal SIM, so calls and bank codes still reach you.

FREE VPN ON EVERY PLAN
Every active plan includes a VPN with 15 locations. Most eSIM apps charge extra for this or do not offer it at all. Hotel Wi-Fi, airport Wi-Fi and cafe networks are shared with strangers; the VPN is one tap away.

200+ COUNTRIES, 100+ CITIES, REGIONAL PLANS
Buy a plan for a single country, a single city if your trip is short, or a regional plan that follows you across borders. Europe on one eSIM. Asia on one eSIM. No swapping SIMs at every crossing.

PRICES YOU CAN SEE BEFORE YOU PAY
Plans start from $0.95. Data amount, validity and coverage are shown on the plan card before checkout. No auto-renewal you have to remember to cancel.

WHAT YOU CAN DO IN THE APP
- See exactly how much data is left, straight from the operator
- Top up the same eSIM in one tap when data runs low, no new QR code
- Install with one tap on iPhone and Android, no codes to type
- Reset a stuck data session yourself if the network drops
- Check coverage and local networks per country before you buy

BEFORE YOU BUY
Your phone must be eSIM capable and carrier unlocked. Most phones released since 2018 qualify: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later. The in-app checker confirms yours in seconds.

HONEST ABOUT WHAT IT IS NOT
A travel eSIM gives you mobile data. It does not give you a local phone number, so if you need to receive local SMS from a domestic service, keep a local SIM as well. We would rather tell you now than after you land.

SUPPORT FROM PEOPLE
Real support in 31 languages, usually answering within a few hours. Not a chatbot loop.

What’s new

Before installing, a clear warning now appears: do not delete your eSIM. If it seems not to work it is almost always a setting — but deleting is permanent and the QR code cannot be scanned again. The usage screen now explains that data is reported by the network and can be up to 45 minutes behind. Cancelled lines are no longer attached to support requests.
