Purchase your eSIM online, receive a QR code via email, and scan it with your smartphone's camera. The setup process is quick and enables immediate data access upon arrival, letting you order an Uber or check directions right away.

For most New York City visitors, a Cellesim eSIM plan with 5GB to 10GB of data is sufficient for a 5-7 day trip.

While some public Wi-Fi exists in NYC parks and cafes, its reliability and security can be inconsistent, especially in high-traffic areas like subway stations or tourist spots. For secure, consistent, and fast internet access across all of New York, a Cellesim eSIM is far superior, ensuring you're always connected without searching for hotspots.

Cellesim eSIMs primarily provide mobile data for internet access in New York. While they don't typically come with a local phone number for traditional calls and SMS, you can easily make calls and send texts using internet-based apps like WhatsApp, FaceTime, or Skype, leveraging your eSIM's data connection. This is generally more convenient for international travelers.

Look up your phone’s exact model number with the manufacturer to see if it’s listed as compatible, and make sure your phone is not carrier-locked. Seeing an EID number or an “Add eSIM” option in your settings is a good sign, but some phones have regional restrictions. If you’re not sure, please contact our support team before you buy.

No. An eSIM can be installed only once, and it locks to the first device it is installed on. It cannot be moved to another phone, re-scanned, or reinstalled afterward, and it is non-refundable once installed. Please install your eSIM on the device you plan to keep using. If you are switching devices and need help, contact our support team.

Yes. With Cellesim you top up the eSIM you already installed. You do not scan a new QR code, you do not install a second profile, and your phone number setup does not change.

Open the Cellesim app or your account page, pick a top-up for the eSIM you are using, and the data is added to the same line. The validity period is extended at the same time, so a 7-day plan topped up on day 5 keeps running instead of expiring.

This matters most when you are already travelling: running out of data usually means you have no connection to buy more with. Because the top-up lands on the existing profile, it works as soon as it is processed, without Wi-Fi and without reinstalling anything.
