Find what you want to know
Yes. Most modern smartphones support dual-SIM functionality, which allows you to use an eSIM and a physical SIM simultaneously. This is useful if you want to: • keep your main phone number active, • use a travel eSIM for mobile data, • separate personal and work lines, • have backup connectivity while traveling. Your device settings allow you to choose which line is used for calls, messages, and mobile data.
No. Switching to an eSIM does not automatically change or cancel your phone number. If you convert your main SIM to an eSIM through your mobile operator, your number, plan, and account remain the same. If you use a travel eSIM from ESIMPLE, your main SIM stays active and unchanged
Yes. eSIM works internationally and is especially convenient for travel. With eSIM, you can: • stay connected abroad without changing physical SIM cards, • keep your home number active for calls and messages, • activate regional or global data plans instantly. This makes eSIM a flexible option for short trips, long stays, or frequent travel.
Most smartphones can store multiple eSIM profiles, although only one or two can be active at the same time. Inactive profiles remain saved on your device and can be reactivated later without downloading them again. The exact number of supported profiles depends on your device model and software version.
Yes. You can switch between eSIM profiles directly in your phone’s settings. You can: • activate or deactivate profiles, • choose which line is used for data, • assign different lines for calls and messages. Switching usually takes only a few seconds and does not require internet once the profiles are already installed.
You can check eSIM compatibility in your phone settings. Common ways include: • checking SIM or network settings for eSIM options, • dialing *#06# and looking for an EID number, • reviewing your device specifications on the manufacturer’s website. Most smartphones released in recent years support eSIM.
Yes. An eSIM works like a regular SIM card and supports hotspot and tethering features. You can share your mobile data connection with other devices through your phone’s hotspot settings, depending on your device and plan conditions.
No. Each eSIM profile can only be active on one device at a time. This is a security measure that prevents unauthorized use and ensures accurate billing. If an eSIM is activated on another device, the previous activation is automatically disabled.
If the QR code does not scan, try the following: • make sure your camera lens is clean and lighting is good; • hold the phone steady and adjust the distance; • use manual activation instead of scanning; • update your device software; • restart your phone and try again. If the code has expired or still doesn’t work, request a new activation code from support.
This usually means that: • the eSIM profile is already installed on your device; • the activation code has already been used; • the activation code has expired. You can resolve this by checking existing eSIM profiles, removing inactive ones, or requesting a new activation code.
Deleting an eSIM profile removes it from your device and immediately stops service on that line. For travel eSIMs, deletion is usually permanent and cannot be restored. If deleted by mistake, a new eSIM may need to be purchased or reissued.
You need an internet connection only for the initial activation. Once activated, the eSIM works like a regular SIM: • calls and messages function normally, • mobile data provides internet access on its own. Wi-Fi is recommended for activation when available.
Yes. eSIM technology is considered very secure. Because eSIMs are built into the device: • they cannot be physically removed or copied, • profiles are encrypted and digitally signed, • lost or compromised eSIMs can be disabled remotely. This reduces risks associated with SIM theft or unauthorized use.
