Question 24

How many eSIM profiles can I store and run on my phone at the same time?

Accepted Answer

Storage: Most modern smartphones allow you to download and store between 5 and 10 distinct eSIM profiles directly on their internal chip.Usage: While you can store many, you can generally only run one or two profiles actively alongside your primary home SIM card at any given time, depending on your device generation.

Question 25

Will this eSIM work on a jailbroken (iOS) or rooted (Android) device?

Yes, but we cannot guarantee optimal network performance because jailbreaking or rooting modifies core security protocols. Security flags within cellular operating systems can occasionally interfere with the profile registration process or prevent automatic network connections.

Question 26

Can I keep my home SIM in my phone alongside the eSIM {{Country}}?

Accepted Answer

Yes, modern smartphones feature Dual SIM technology, allowing your physical home SIM and your digital eSIM {{Country}} to run simultaneously.

Question 27

Can I keep my original WhatsApp and iMessage accounts?

Accepted Answer

Yes, these services are linked to your home phone number or account rather than the SIM card. When you insert your eSIM {{Country}}, your apps may prompt you to update your number—always select Keep Existing Number. This ensures your account, chat history, and contacts remain tied to your home number, allowing you to message and call as usual throughout your trip.

Question 28

Does my {{Country}} unlimited data eSIM have a hidden Fair Usage Policy (FUP) throttle?
