FAQ

An eSIM (embedded SIM) is a digital SIM built into your phone, tablet, or smartwatch. Instead of inserting a physical SIM card, you install a mobile data plan directly onto your device using a QR code or activation link. It works exactly like a traditional SIM, just without the plastic.

You purchase a data plan for the country or region you're visiting, install it on your device before or during your trip, and connect to a local network the moment you land — no roaming charges from your home carrier, no searching for a local SIM shop at the airport.

Yes, you'll need a WiFi or data connection to download and install your eSIM profile. We recommend installing it before you travel, while you're still connected to WiFi at home.

Yes. Most modern smartphones support Dual SIM, meaning you can keep your regular SIM active for calls and texts while using your Maxesimo eSIM for data. You stay reachable on your usual number without paying roaming fees.

Most smartphones released from 2018 onwards support eSIM, including recent iPhone, Samsung Galaxy, and Google Pixel models. Visit our Compatible Devices page for a full, up-to-date list before you buy.

Yes, iPhone XS and newer models support eSIM. Note that iPhones purchased in mainland China do not include eSIM functionality.

Yes, most flagship Android devices from Samsung, Google, and other major manufacturers support eSIM. Check our compatibility list, as support varies by model and region.

If your phone is locked to a specific carrier, it may not accept a different eSIM profile. Contact your carrier to confirm your device is unlocked before purchasing.

After purchase, you'll receive a QR code and manual activation details by email. Scan the QR code in your phone's settings, or enter the details manually. Full step-by-step instructions are on our eSIM Setup Guide page.

You can install the eSIM profile anytime after purchase, but most plans only start counting data usage once your device connects to a network at your destination — so it's safe to install before departure and activate on arrival.

No, you'll need a second device (or a printed/saved copy of the QR code) to scan it, since you can't scan a QR code displayed on the same screen you're installing it to. Manual installation is available as an alternative.

Make sure your screen brightness is turned up and the code isn't cropped. If scanning still fails, use the manual installation option with the SM-DP+ address and activation code provided in your confirmation email.

Once your data allowance is used, your eSIM will stop providing internet access. You can purchase a new plan or a top-up at any time through our website.

Our plans are data-only, designed for internet access — browsing, maps, messaging apps, and social media. For calls and texts, keep your primary SIM active alongside your eSIM.

Yes, in most cases you can share your eSIM's data connection with other devices via personal hotspot, the same way you would with a regular SIM.

Validity periods vary by plan and are listed on each product page — typically ranging from a few days to a month, depending on the package you choose.

Yes, you can check your usage at any time by logging into your Maxesimo account or contacting our support team.

We offer eSIM data plans for 189+ destinations worldwide, including single-country plans, regional bundles, and global packages. Browse all available destinations on our country plans page.

Yes, our regional and global plans are built for multi-country trips, so you don't need to buy a separate eSIM for every border you cross.

As long as it's installed before your trip, your eSIM will connect automatically to a local partner network as soon as your device detects service on arrival.

Yes. If you're travelling across multiple countries in the same region — for example several European or Latin American countries — one of our Regional eSIM plans covers all of them with a single data plan, so you don't need to switch eSIMs at every border.

Yes. Our Global eSIM plan is designed for travellers visiting multiple continents or countries outside a single region, giving you one data plan that works across our full global coverage.

We accept all major credit and debit cards, as well as Apple Pay and Google Pay at checkout, giving you a fast and secure way to pay.

Refund eligibility depends on whether the eSIM has been installed or activated. Full details are available in our Terms and Conditions.

Yes, all transactions are processed through secure, encrypted checkout systems. Maxesimo does not store your full card details.

First, check that data roaming is switched on for your eSIM line in your device settings, and that the eSIM is set as your active data line. If the issue continues, contact our support team with your order number.

Our support team is available before, during, and after your trip. Visit our Help Center for contact details and troubleshooting guides.

eSIM profiles are generally tied to the device they were installed on and can't be transferred once activated. You'll need a new eSIM plan for a new device.
