What OXeSIM is

OXeSIM provides digital eSIM plans designed to keep travel connectivity simple, fast, and clear. Our platform is built to reduce confusion for both technical and non-technical travelers by removing unnecessary steps, unnecessary marketing clutter, and complicated top-up flows.

Main eSIM plan types

Local eSIM
One eSIM for one country.

Regional eSIM
One eSIM for multiple countries within one region.

Global eSIM
One eSIM for worldwide travel across supported destinations.

Core model

All OXeSIM plans are designed around:

  • instant digital delivery
  • no physical SIM card
  • simple activation flow
  • broad destination coverage across supported plans

Some destinations may not appear at certain times because of temporary availability limits or compliance requirements.

How to choose the right plan

Go to eSIM Plans in the main header and choose:

  • Local
  • Regional
  • Global
  • All eSIMs

Then select your destination and compare the available plans on that page. You can also use the search bar to find your destination faster.

Standard vs Unlimited vs Data/Calls/Texts

Standard
Includes a fixed data amount.

Unlimited
Designed for travelers who want the most flexible data option.

Data/Calls/Texts
Includes data plus calling minutes and SMS, when available.

Not every destination includes Data/Calls/Texts plans. If available, they will appear on the plan page.

Regional and Global country coverage

If you are viewing a Regional or Global plan, click View Country Coverage to see supported countries for that plan. This list is provided for general guidance. Final coverage, speed, and network details are available after purchase through Manual Install – PIN: XXXX in My eSIMs.

Local plans do not show View Country Coverage because they are built for one country only.

When the plan starts

Your package starts when you connect to a supported network in a supported destination.

For Regional and Global plans, if you are already in a covered country when you activate the eSIM, the plan may start immediately.

When to buy before travel

We recommend purchasing your eSIM within 30 days before travel and installing it before your trip while you still have a stable internet connection.

Minimum device requirements

To use an OXeSIM plan, your device must:

  • support eSIM technology
  • be carrier-unlocked
  • not be jailbroken on iPhone
  • not be rooted on Android

Compatibility checker

Click Check Device Compatibility on the plan page. Our compatibility list is provided for general guidance only.

Compatibility may vary depending on:

  • model
  • region
  • carrier
  • operating system version

Customers are responsible for confirming compatibility before purchase.

Important note

Device incompatibility is not a valid refund reason. Please confirm compatibility before ordering.

Account requirement

An account is required before completing checkout.

For a faster and smoother checkout experience, OXeSIM includes the account step directly inside the Secure Checkout page using the same Email and Password fields.

This means customers do not need to visit a separate Register page during checkout. It helps both technical and non-technical customers complete checkout with fewer steps.

If you are already logged in, the Email and Password fields will not appear, and you can complete checkout directly.

Sign in or create an account

At Secure Checkout, the same Email and Password fields are used for both returning customers and first-time customers.

If you already have an account:

  • enter your existing OXeSIM email and password

If this is your first time:

  • enter your email
  • create a password in the Password field
  • complete payment

After successful payment, our system will automatically create your OXeSIM account using the email and password you entered during checkout.

You do not need to click a separate Register button during checkout.

If you are already logged in, you will skip this step and continue checkout directly.

The separate Login/Register page can still be used outside checkout, but checkout skips that extra step to make the purchase process faster, smoother, and easier.

Checkout details

At checkout, you will:

  • select your billing country
  • enter your email and password if you are not already logged in
  • review your eSIM details and subtotal
  • enter a promo code if you have one
  • choose an available payment method
  • complete payment

Returning customers should use their existing OXeSIM password.

First-time customers should create a password in the Password field. After successful payment, our system will automatically create the account.

If you are already logged in, the Email and Password fields will not show, and you can complete checkout directly.

Available payment methods are shown during checkout. If you are using a supported Apple device, you may also see Buy with Apple.

After successful payment

After a successful purchase, first-time customers will have their OXeSIM account created automatically by our system.

You will see your order details, including the eSIM Installation & Usage section, and you can access your eSIM from My eSIMs.

Where to access your eSIM

After purchase, the best place to access your eSIM is:

→ My eSIMs

You will also receive a confirmation email, but My eSIMs is the recommended and easiest place to manage your eSIM.

Installation priority order

Use the available installation options in this order:

  1. Install eSIM
    Best option when available on supported iPhone and iPad devices. This is the fastest and easiest method.
  2. Show QR Code
    Use this if Install eSIM is not available, or if you are using a computer or another device to access your order.
  3. Manual Install – PIN: XXXX
    Use this if you need the manual setup option or more detailed installation and network information.

Best recommended installation method

If Install eSIM is available on your supported iPhone or iPad, use that first.

If it is not available, use Show QR Code.

Use Manual Install – PIN: XXXX only when you need the manual option.

After the eSIM is installed

Go to:

Settings → Cellular

Then:

  • open the OXeSIM line
  • make sure Turn On This Line is on
  • turn Data Roaming on

IMPORTANT/ Then go to:

Settings → Cellular → Cellular Data

Select the OXeSIM line.

If you purchased Data/Calls/Texts

Also go to:

Settings → Cellular → Default Voice Line

Select the OXeSIM line.

Is manual configuration always required?

No. In most cases, setup is mostly automatic after installation. You may only need to confirm:

  • the OXeSIM line is on
  • Data Roaming is on
  • the OXeSIM line is selected under Cellular Data
  • Default Voice Line is selected if your plan includes calls and texts

Low Data Mode

To reduce unnecessary background usage, we recommend enabling Low Data Mode after installation.

How do I install my OXeSIM eSIM on Android?

After purchase, open your eSIM in My eSIMs and tap Show QR Code.

On your Android phone:

Step 1
Open Settings → Connections → SIM manager.

On some Android phones, this may appear under Network & Internet or SIMs.

Step 2
Tap Add eSIM and follow the setup steps.

Keep the screen open while your eSIM installs. Setup may take a few minutes.

Once installation is complete, tap Done.

Step 3
Keep Calls and Messages on your main SIM.

For Mobile data, choose your OXeSIM eSIM, then tap Change to confirm.

Most OXeSIM plans are data-only, so keep your primary SIM selected for calls and texts unless your plan includes calls and SMS.

Step 4
Open Connections again, go to Mobile networks, and make sure Data roaming is turned on.

Data roaming must be enabled for your OXeSIM eSIM to connect properly.

Your OXeSIM eSIM is now ready to use.

What if my Android settings look different?

Some Android phones use different names.

You may see:

  • Connections
  • Network & Internet
  • SIM manager
  • SIMs
  • Mobile network
  • Mobile networks

The goal is the same: add the eSIM, select it for Mobile data, and turn Data roaming on.

Should Calls and Messages stay on my main SIM?

Yes. Most OXeSIM plans are data-only, so keep Calls and Messages on your main SIM unless your plan includes calls and SMS.

Why is Data roaming required?

Data roaming must be turned on so your OXeSIM eSIM can connect properly to supported networks.

What if my Android eSIM is installed but not working?

Go to Settings → Connections → SIM manager and make sure your OXeSIM eSIM is selected for Mobile data.

Then go to Mobile networks and make sure Data roaming is turned on.

  • expiration date after activation

Status labels

Your eSIM may show one of these statuses:

Using the same eSIM again

OXeSIM does not rely on a traditional top-up flow.

If you want to use the same eSIM again:

  • go to My Account → My eSIMs
  • open the eSIM you want to use again
  • click Order again
  • complete checkout
  • activate it the same way

This is OXeSIM’s simplified reuse flow, which can fit both tech and non-tech users.

eSIM installed but no connection

Go to:

Settings → Cellular

Then:

  • open the OXeSIM line
  • make sure Turn On This Line is on
  • turn Data Roaming on

Then go to:

Settings → Cellular → Cellular Data

Select the OXeSIM line.

eSIM installed but still not working

Most common reason, IMPORTANT: Settings → Cellular → Cellular Data Select the OXeSIM line.

Check the following:

  • you are in a supported destination
  • you are connected to a supported network
  • the OXeSIM line is turned on
  • Data Roaming is turned on
  • the OXeSIM line is selected under Cellular Data

If your plan includes calls and texts, also check:

  • Settings → Cellular → Default Voice Line

Select the OXeSIM line there too.

I do not see Install eSIM

Install eSIM is only available on supported iPhone and iPad devices.

If it is not shown:

  • use Show QR Code
  • if needed, use Manual Install – PIN: XXXX

Best time to install

We strongly recommend installing and activating your eSIM before travel while you still have a stable internet connection.

Example: if a traveler is flying from Los Angeles to Paris, it is better to complete installation before departure or while still at the airport, rather than waiting until connectivity becomes limited.

Can I remove and reinstall my eSIM?

No. Removing and reinstalling an eSIM is not a supported troubleshooting step.

Once an eSIM is installed on your device, do not remove it. If you have connection issues:

  • keep the eSIM installed
  • restart your device
  • follow the steps in this documentation and Help Center

Warning: eSIMs cannot be reinstalled after uninstalling.

Refund policy

All sales are final to the maximum extent permitted by law.

Once an eSIM is issued, assigned, delivered, displayed, installed, activated, or used in whole or in part, it is non-refundable and non-cancellable.

Device compatibility and refunds

Customers are responsible for confirming device compatibility before purchase. Orders made on incompatible devices are not refundable.

Zero usage

Zero usage does not make an order refundable after delivery.

Destination availability

If a destination is not listed, it may be temporarily unavailable or unavailable due to compliance requirements.
