FAQ

When does my plan validity start?

Your plan validity ONLY starts when you manually tap "Activate" in the ByteSIM App. It does NOT start after payment, so you can safely buy now and activate when you arrive.

Can I get a refund if my plans change?

Once the eSIM order is confirmed, it is non-refundable. Please ensure your device is eSIM-compatible and unlocked before purchasing.

Where is the IP address located?

The IP address for this eSIM is located in the US.

Can I top-up or extend the plan?

Yes, you can top-up by contacting our 24/7 WhatsApp or email customer support. However, we highly recommend purchasing a new eSIM instead, as top-up rates are generally more expensive.

Can I share my connection via hotspot?

Yes, you can share your connection with other devices, but it is subject to a 10GB hotspot limit.
