Can You Use an eSIM on a Locked Phone?
A travel eSIM usually will not work on a carrier-locked phone unless it comes from the same carrier. Before purchasing an eSIM, make sure your device is unlocked, eSIM-compatible, and supported in your destination to avoid installation, activation, or connectivity problems.
Can You Use a Hotspot with an eSIM?
Yes, you can use a hotspot with an eSIM when your phone supports tethering and the eSIM plan allows it. An eSIM hotspot lets you share mobile data with laptops, tablets, or other phones, making it useful for travel, remote work, and situations where public Wi-Fi is unavailable or unreliable.
Does an eSIM Change Your Phone Number?
An eSIM does not automatically change your phone number. Learn how travel eSIMs work, when you keep your existing number, how WhatsApp and iMessage are affected, and the best way to stay connected abroad without expensive roaming charges.
Can I Use WhatsApp with an eSIM?
Yes, you can use WhatsApp with an eSIM. Your WhatsApp account stays linked to the phone number you originally registered, not to the SIM or eSIM providing your internet connection. That means you can keep using your existing WhatsApp number while a Mobisim travel eSIM handles your mobile data abroad. In most cases, there's no need to change your number, create a new account, or update your contacts. Just make sure your WhatsApp account is already active before you travel, as reinstalling the app or switching phones may require receiving a verification code via SMS or phone call.
eSIM vs Pocket WiFi: Which One Should Travelers Use?
Choosing between an eSIM and Pocket WiFi depends on how you travel.

Pocket WiFi remains a practical option for families or groups sharing multiple devices, but for solo travelers, couples, and frequent international trips, an eSIM is typically the simpler, lighter, and more flexible solution.
