A ByteSIM eSIM is a prepaid digital travel SIM for compatible, carrier-unlocked phones and tablets. After purchase, install the eSIM, select it for mobile data and connect to a supported local network at your destination—without replacing your physical SIM card.
A prepaid ByteSIM travel eSIM can help you avoid expensive home-carrier roaming data charges. Plan prices and allowances are shown before purchase. To reduce accidental roaming costs, choose ByteSIM for mobile data, turn off cellular data switching and disable data roaming on your primary SIM.
Your device must support eSIM and be carrier-unlocked. Compatibility can vary by model and sales region, even within the same phone family. Check the ByteSIM eSIM-compatible device list before purchasing.
Install your eSIM before departure while you have a stable Wi-Fi connection. Most ByteSIM plans activate when the eSIM first connects to a supported network at your destination. Some special plans start on a selected date or require activation through the ByteSIM App. Installing early does not always start the plan.
Yes, most dual-SIM devices let you keep your primary SIM active and use ByteSIM for mobile data. You can continue receiving calls or texts on your original number, but your home carrier may charge for roaming calls or messages. Check its rates and keep data roaming disabled on the primary SIM.
Most ByteSIM travel eSIM plans do not require passport or ID verification. Some destinations or local-number plans may require identity verification under local regulations. Any requirement is shown in the product details before purchase.
Selected ByteSIM plans offer unlimited data, 5G and access to multiple local carriers for broader coverage. Availability varies by destination and plan. Unlimited plans may be subject to a fair use policy, while actual speed and latency depend on local coverage, your device and network conditions. If you experience weak signal or unstable service, contact ByteSIM 24/7 support. Where available, we can help switch the connected carrier or replace the eSIM resource to improve connectivity.
Selected ByteSIM plans include a local phone number, calls and SMS, while other plans are data-only. Hotspot sharing is supported on most plans but can vary by product or carrier. With a data-only eSIM, you can still use internet calling and messaging apps such as WhatsApp, iMessage or Telegram.
For supported plans, check plan status and data usage in the ByteSIM App for iOS or Android. Your device’s mobile-data counter can also help you estimate usage.
If the eSIM does not connect, enable the ByteSIM line, select it for mobile data and turn on data roaming for the ByteSIM line. Restart the device or toggle airplane mode, then follow the APN or network-selection instructions in your order. ByteSIM customer support is available 24/7.
Most eSIM profiles are intended for one device and may not be transferable or reinstallable after deletion. Keep the ByteSIM eSIM installed until your trip and plan are complete. Before changing phones, resetting your device or deleting the eSIM, contact ByteSIM support because transfer or reissue availability depends on the plan and carrier.
