An eSIM is a digital SIM profile that installs on your phone without a plastic card. With a travel eSIM you buy a data plan online before or during a trip, install it as a second line, and use local data instead of paying your home carrier's roaming rates. Your home number stays active for calls and texts, while the travel line handles internet.
Maya Mobile sits in that category. It sells travel eSIM data plans through its website at maya.net and through the Maya app, and delivers the eSIM as a QR code by email and inside your account. The audience it is aimed at is straightforward: short-trip travellers with eSIM-compatible phones who would rather buy data than be billed for roaming.
The plan range is built around fixed durations, typically 3, 7, 14 and 30 days, with the duration chosen using a billing-cycle selector before checkout. Alongside those, Maya offers:
Unlimited-data options that cover a large list of destinations from a single eSIM
Coverage on a number of cruise lines
Traditional prepaid data plans measured in gigabytes for specific countries and regions
Entry pricing for the shortest plans falls in the sub-$10 range, so the sums involved on a short trip are small. That matters when you are working out how much a percentage discount is worth in practice.
EDC10OFF is a 10% discount code, used in listings as both a discount code and a promo code. It is applied to the plan price at checkout, before payment is taken, rather than afterwards as a credit or rebate. In other words, it is the last step of an otherwise normal purchase: pick a destination, pick a duration, sign in, then apply the code.
The field you need is the promo or discount code box on the checkout or payment screen. In the app it appears with the order summary before payment. It is sometimes collapsed behind a "Have a code?" link, so if you cannot see a box at first glance, look for that link rather than assuming the option is missing.
Open the Maya Mobile site or app and choose a destination, or the global unlimited plan.
Select the plan length using the duration or billing-cycle selector.
Create an account or sign in, so the eSIM is tied to your account.
On the checkout or payment screen, enter EDC10OFF in the promo or discount code field and confirm it.
Check the total has dropped by 10% before you submit payment.
That last check is the only reliable confirmation that the code has registered.
Installation needs an internet connection, so it is best done at home over Wi-Fi rather than on arrival. On iPhone you scan the QR code with the camera, or press and hold the image to add the eSIM. On Android the install option sits in mobile network settings. If scanning is impractical, manual entry using an activation code is available.
Once you land, two settings matter. Data roaming must be switched on for the Maya line, because it roams onto local partner networks. Data roaming on your home SIM should be switched off, so your own carrier does not bill you. Then set the Maya eSIM as your cellular data line.
The profile stays on the phone afterwards, so future plans can be bought against it without reinstalling. Auto top-up can be left off if you do not want the plan to renew.
Percentage codes such as this one usually apply to a single plan purchase and normally do not combine with another promotion. Whether EDC10OFF stacks with other offers is not stated, so treat it as a standalone saving.
Several Maya unlimited plans carry a daily high-speed allowance, after which speeds can change for the rest of that day. The exact allowance is set out on each plan page. Maya publishes a refund policy for eSIMs that cannot be installed or do not work, with limits tied to data already used; the specifics are on the site.
On devices, eSIM support is standard on recent iPhone, Samsung Galaxy and Pixel handsets, while carrier-locked phones and older models may be excluded. The detailed compatibility list is not reproduced here, so check it before paying. Finally, a discount taken on a first purchase should not be assumed to carry over to auto top-up renewals.
