How can we help you?

An eSIM is a digital SIM built directly into your smartphone's hardware. Instead of inserting a physical card, you download a carrier profile by scanning a QR code. This lets you switch carriers or add a second data plan instantly without touching your SIM tray. Roamix supplies eSIM profiles you can activate in minutes for mobile data abroad.

After purchasing, check your email for the QR code or access it from your Roamix dashboard. On iPhone: go to Settings, Cellular, Add eSIM, then tap Use QR Code. On Android: go to Settings, Network and Internet, SIMs, then Add SIM and scan the code. Follow the prompts to set it as your data line. The full process takes under 2 minutes.

Most smartphones released after 2018 support eSIM, including iPhone XR and XS and all newer iPhones, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and flagship Android devices from Motorola, OPPO, and Xiaomi. Your device must also be carrier-unlocked. Use our free Compatibility Checker to verify both requirements automatically.

Yes, and this is one of the main advantages of eSIM over swapping physical SIM cards. In dual-SIM mode, your home SIM stays active for calls and texts while the Roamix eSIM handles all your mobile data. In your phone's cellular settings, set the Roamix eSIM as Mobile Data and your home SIM as Calls and SMS.

Refunds are available for eSIM plans that have not been installed or activated within 14 days of purchase. Once the QR code is scanned and the eSIM profile added to a device, the plan is considered activated even if no data was used. Contact support@roamix.app if a technical issue prevented your eSIM from working.

Yes. Roamix provides 5G connectivity in countries where our network partners support it, including parts of the US, UK, Europe, Japan, South Korea, and Australia. In areas without 5G, your device automatically falls back to the fastest available speed, typically 4G LTE. Availability depends on local infrastructure and your device's band support.

Yes, this is a common setup step. Go to Settings, Cellular (iPhone) or Settings, Network and Internet, SIMs (Android), select your Roamix eSIM line, and enable Data Roaming. Without data roaming on the eSIM line, your device will not connect to local partner networks abroad. Keep data roaming off on your home SIM line to avoid carrier charges.

Proceed with caution. Deleting an eSIM profile from your device may be permanent. Some profiles can be re-downloaded from your Roamix account, but others cannot. Before deleting, check whether your specific plan supports re-download. If you are switching to a new phone, contact Roamix support before removing the eSIM to see if it can be transferred.

The most common causes are Data Roaming not enabled on the Roamix line, the eSIM not set as your default data line, or the plan not yet activated because you have not arrived at your destination. Toggle airplane mode off and on, then contact support@roamix.app with your device model and order number if issues persist.

Yes. Your Roamix dashboard lets you manage all your eSIM purchases in one place. You can view plan details, check data usage, download QR codes, and purchase additional plans for different devices or trips from a single login. This is particularly useful for families or teams where multiple people need eSIM plans.
