Frequently Asked Questions

What devices are compatible with eSIMs?

Most modern smartphones and tablets support eSIM technology, including iPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer, and many iPad models. You can check your device compatibility on the provider's website before purchasing.

How do I activate an eSIM?

Activation processes vary slightly by provider, but generally involve scanning a QR code or entering activation details in your device settings. eSIMFOX offers a simple 3-step process: purchase online, scan the QR code, and activate the plan when you're ready to use it.

Can I use my regular phone number with an eSIM?

Yes, one of the advantages of eSIM technology is that you can keep your physical SIM card (and phone number) active while using an eSIM for data. This allows you to receive calls and texts on your regular number while using local data rates abroad.

What happens when my eSIM data runs out?

When your data allowance is depleted, you can easily purchase additional data through the provider's app or website. Some providers like eSIMFOX allow you to top up your existing plan, while others may require purchasing a new plan.

Are unlimited data plans truly unlimited?

Most "unlimited" plans have fair usage policies. For example, Holafly's unlimited plans may reduce speeds after a certain amount of data usage. eSIMFOX's approach of offering specific data allowances often provides better value and more predictable performance.
