Why is my eSIM internet slow, and how can I fix it?
If your eSIM is connected but speeds feel slow, it's usually due to one of a few common factors: network congestion, local carriers prioritising their own users, signal strength in your area, or outdated device software.
Try restarting your device or checking for software updates first — this resolves most cases. Otherwise, feel free to email us at support@hsim.io.
