Question 1

When should I install my eSIM?

Accepted Answer

Install your eSIM as soon as you purchase. Activation happens later — your data plan only starts when you connect to a supported network in your destination country, so installing early is safe and saves time on arrival.

Question 2

How do I use my eSIM?

Accepted Answer

Once installed, set the eSIM as your data line in Settings > Cellular/Mobile. Turn on data roaming for that line (this won't trigger roaming charges — it's required for the eSIM to connect). When you land, your phone connects automatically.

Question 3

Can I reuse my eSIM?

Accepted Answer

Yes. Your eSIM stays installed on your device. To use it again on a future trip, just buy a new package for the same destination through your account or top up the existing one if your current plan is still active.

Question 4

What are renewals?

Accepted Answer

With renewals, you can automatically renew your package when your eSIM has 10% data remaining. Turn renewals on and off from your eSIM's details — no commitment.

Question 5

What is an eSIM?

Accepted Answer

An eSIM (embedded SIM) is a digital SIM that lets you activate eSIM data plans without a physical SIM card. It's built into your device, holds multiple carrier profiles, and is ideal for travel.

Question 6

How do I check if my device supports eSIM?

Accepted Answer

Most modern smartphones support eSIM, including iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer. Check Settings > Cellular/Mobile on your device for an option to add an eSIM.

Question 7

Can I keep my regular phone number?

Accepted Answer

Yes. Your eSIM works alongside your existing physical SIM. Keep your regular number for calls and texts on the physical SIM, and use the eSIM for data while travelling.

Question 8

What happens if I run low on data?

Accepted Answer

You can top up the same roamfly eSIM directly from your account in under 30 seconds — no need to install a new eSIM or restart your phone. Your existing plan stays active until the top-up applies.

Question 9

Do unlimited plans have any limits?

Accepted Answer

Yes — most unlimited plans include a fair-use cap, typically 1–2 GB of high-speed data per day. After the cap your phone stays connected, just at reduced speeds. You'll never be charged extra or cut off.
