Frequently Asked Questions

Discover more about using international eSIM for prepaid data, or contact our team directly for expert assistance.

My eSIM doesn’t work? ✚
1).Select eSIM as your Mobile Data. 2).Turn on data roaming. 3).Manually switch your network to the operators marked in the product description. 4).Restart your phone may also help.
Why does my eSIM have unlimited data but still experience speed limits? ✚
Unlimited bundles provide 1GB of data at unthrottled 5G (where available) speeds per 24 hours, after which unlimited data is available at 512kbps. The 24-hour period is calculated from the first use, and each day, the 1GB of unthrottled data resets for the next 24-hour cycle. In rare cases, operators may implement an international Fair Usage Policy (FUP) to ensure equitable internet usage and maintain optimal connections for all users. This policy targets those who consume large amounts of data in a short period, such as through frequent live streaming or movie watching, by temporarily reducing their network speed or deprioritizing their connection. Even with this speed limit, you can still enjoy HD streaming (1080p) without significant interruption. Typically, these speed restrictions last no longer than one day. Although ByteSIM cannot control this policy, you can be assured that any imposed limits will be lifted the following day, restoring your original plan speed.
If I lost my eSIM QR code, what can I do? ✚
Log in to the eSIM1st app. Navigate in your eSIM to view the QR code. Alternatively, you can register as a user, and we can resend the QR code to your email upon request.
Weak signal or no network after activating the eSIM? ✚
Verify that the eSIM profile is enabled. Toggle Airplane Mode on and off to refresh network connections. Reset network settings. Contact your carrier to confirm network coverage in your area.
The eSIM worked at home but stopped after entering a new country? ✚
Ensure roaming is enabled for the eSIM. Check that the carrier supports roaming in the destination country. Purchase a local eSIM plan for better connectivity abroad.
eSIM doesn’t work on your new device after switching phones? ✚
Contact your carrier to deactivate the eSIM on your old device and activate it on the new one. Use the carrier’s app or website for quick eSIM transfers if supported.
