Question 1

What is an eSIM and how is it different from a regular SIM?

Accepted Answer

An eSIM (embedded SIM) is a digital SIM built directly into your smartphone's hardware. Unlike a physical SIM card, you don't insert or swap it — instead, you download a carrier profile digitally, usually by scanning a QR code. This means you can switch carriers or add a second data plan instantly, without touching your phone's SIM tray. Roamix supplies eSIM profiles you can activate in minutes, giving you mobile data abroad without roaming fees.

Question 2

How do I install my Roamix eSIM?

Accepted Answer

After purchasing a Roamix plan, check your email for the QR code (also accessible from your account dashboard). On iPhone: go to Settings > Cellular > Add eSIM, then tap 'Use QR Code'. On Android: go to Settings > Network & Internet > SIMs > Add SIM, then scan the QR code. Follow the prompts to label the plan and set it as your data line. The whole process takes under 2 minutes. For detailed step-by-step instructions, see our Installation guides.

Question 3

Is my phone compatible with Roamix eSIM?

Accepted Answer

Most smartphones released after 2018 support eSIM, including iPhone XR/XS and all newer iPhones, Samsung Galaxy S20 series and newer, Google Pixel 3 and newer, and flagship Androids from Motorola, Oppo, Xiaomi, and others. Your device must also be carrier-unlocked. Use our free Compatibility Checker tool to verify both requirements automatically, or follow the manual steps in our Getting Started guides.

Question 4

Can I use my home SIM while using a Roamix eSIM abroad?

Accepted Answer

Yes — this is one of the most important advantages of eSIM. Using dual-SIM mode, your physical home SIM remains active for calls and texts (people can still reach you on your usual number), while your Roamix eSIM handles all your mobile data needs. To set this up correctly, go to your phone's cellular settings and designate the Roamix eSIM as the 'Mobile Data' line and your home SIM as the 'Calls & SMS' line.

Question 5

What is your refund policy for eSIM plans?

Accepted Answer

We offer refunds for eSIM plans that have not been installed or activated, within 14 days of purchase. 'Activated' means the QR code has been scanned and the eSIM profile added to a device — even if no data was used. Once an eSIM is installed, refunds are generally not available, but contact support@roamix.app if you experienced a technical problem that prevented the eSIM from working and we will review your case individually.

Question 6

Do Roamix eSIM plans support 5G?

Accepted Answer

Yes. Roamix provides 5G connectivity in countries and regions where our network partners support it, including parts of the US, UK, Europe, Japan, South Korea, and Australia. In areas without 5G coverage, your device automatically falls back to the highest available speed (4G LTE). The specific network technology available at any given location depends on local infrastructure and your device's band support.

Question 7

Do I need to enable data roaming for my Roamix eSIM to work?

Accepted Answer

Yes. This is a common setup issue. Go to Settings > Cellular (iPhone) or Settings > Network & Internet > SIMs (Android), select your Roamix eSIM line, and ensure 'Data Roaming' is toggled ON. Without data roaming enabled on the eSIM line, your device will not connect to local partner networks abroad. This is different from enabling roaming on your home SIM, which you want to keep OFF.

Question 8

Is it safe to delete my eSIM from my device?

Accepted Answer

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 (this is usually shown on the plan page or in your account). If you're switching to a new phone, contact Roamix support before deleting to see if your profile can be transferred.

Question 9

Why is my eSIM not connecting after installation?

Accepted Answer

The most common causes are: (1) Data roaming is not enabled for the Roamix eSIM line (see previous FAQ), (2) The eSIM line is not set as the default mobile data line, (3) Your plan hasn't started yet because you haven't arrived at the destination. Try toggling airplane mode on and off to force a network search. If none of these solve it, contact support@roamix.app with your device model, operating system version, and order number.

Question 10

Can I manage multiple eSIMs under one Roamix account?

Accepted Answer

Yes. Your Roamix dashboard supports managing 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 — all from a single login. This is particularly useful for families or teams where multiple people need eSIM plans for the same trip.
