Description

Cinqstella is a travel eSIM provider that allows you to buy prepaid 4G/5G plans online for over 200 countries and regions, then activate them instantly via a QR code received by email. The offers focus on international and business travelers, with local and multi-region plans for durations of 7 to 30 days, designed to avoid typical roaming fees. Cinqstella emphasizes intelligent switching between partner networks and 24/7 support in Chinese and English, suited for frequent travel and multi-country stays.

How it works

Make sure your smartphone supports eSIM, for example a recent iOS or Android model. Without eSIM compatibility, you won’t be able to use Cinqstella plans.

Go to the Cinqstella website, select the destination country or region, then choose a plan adapted to the desired data volume and duration, before confirming the purchase with an accepted payment method.

After payment, the eSIM QR code is sent immediately to your account’s email address. Keep this email accessible on another device or print it out to easily scan the code.

On iOS, go to Settings then Cellular Data, select Add Cellular Plan and scan the QR code. On Android, the option is in network or SIM card settings depending on the brand, then add a mobile plan by scanning the QR code.

Once the eSIM is installed, select it as your primary or secondary data source in settings and enable data roaming if necessary for the intended destination.

When you arrive in the country, turn on mobile data on the Cinqstella eSIM and let the phone connect to the local network. The plan should activate automatically according to site instructions.

Regularly check your data usage in the phone settings or via your Cinqstella account to avoid exceeding the included volume and plan a new purchase if needed.

FAQ

For a trip of one to four weeks in the United States, it is recommended to choose a local plan for this country with a duration of 7 to 30 days and a data volume of 10GB to 20GB in case of intensive use such as browsing, videoconferencing, or streaming. For lighter use, 3GB to 5GB may suffice.

On most smartphones compatible with eSIM, tethering is technically possible. However, permission to tether sometimes depends on the local network and the chosen plan type, so it is recommended to check the offer conditions before intensive use.

Some Cinqstella plans support voice and SMS, while others are strictly data-only. Before purchasing, check the plan details to see if calls and SMS are included or if you need to keep your physical SIM card for these uses.

After purchase on the site, you immediately receive a QR code by email. Just scan it in your phone settings to install the eSIM, then activate data once arrived at your destination so the plan starts automatically.

Cinqstella targets smartphones compatible with eSIM. Recent iPhone, Google Pixel, and some Samsung and other Android models are generally compatible. Check your model’s eSIM compatibility in the manufacturer’s documentation.

When your data volume is nearly exhausted or your stay extends, you can purchase a new plan on the Cinqstella website using the same email address and install a new eSIM, or use extension options when available.

Yes, most smartphones allow keeping a physical SIM card for local calls and adding a Cinqstella eSIM for international data. This way, you can separate uses and limit typical roaming fees.

Start by checking network configuration, roaming, and selection of the correct data line. If the problem persists, contact the 24/7 Cinqstella support indicating your country, phone model, and order number for quick assistance.
