Sharing your eSIM data connection as a mobile hotspot lets companions use your data plan without buying their own eSIMs. This works well for families, couples, or small groups where one person's plan can cover everyone's needs. Not all eSIM plans allow hotspot sharing, and the speed impact varies.
This guide covers the setup process, which providers allow tethering, and how to minimize data consumption.
Step-by-step instructions
- 1
Verify your eSIM plan allows hotspot sharing
Check your eSIM provider's plan details for 'hotspot,' 'tethering,' or 'data sharing' terms. Airalo allows hotspot on all plans. Saily allows it on all plans.
HelloRoam allows it on all plans. Holafly restricts hotspot on some unlimited plans, particularly in European destinations. Nomad allows hotspot on most plans.
If hotspot is blocked, your phone may show a connected hotspot with no internet for other devices.
Tip: If you are unsure about your plan's hotspot policy, contact the provider's support before traveling. This avoids the frustration of arriving and finding tethering blocked.

Enable hotspot on iPhone
Go to Settings > Personal Hotspot and toggle 'Allow Others to Join.' If you have multiple SIMs, make sure the eSIM is set as your cellular data line under Settings > Cellular > Cellular Data. The hotspot shares data from whichever line is set as the data line. Set a strong password to prevent unauthorized connections.
You can connect up to 5 devices to an iPhone hotspot simultaneously.
Tip: If Personal Hotspot is grayed out, the eSIM's carrier may not have provisioned tethering. Contact your eSIM provider's support to enable it.

Enable hotspot on Android
Go to Settings > Network & internet > Hotspot & tethering > Wi-Fi hotspot. Toggle it on. On Samsung, the path is Settings > Connections > Mobile Hotspot and Tethering > Mobile Hotspot.
Set the network name and password. Android allows up to 10 simultaneous connections on most devices. Make sure the eSIM is set as the active data SIM before enabling hotspot.
Tip: Android offers a 'timeout when no devices connected' option that turns off the hotspot automatically after a set period. Enable this to save battery when others disconnect.

Manage data consumption while sharing
Hotspot sharing drains data faster because multiple devices consume simultaneously. Disable automatic app updates, cloud backups, and HD video streaming on connected devices. Set a data usage warning on your phone under Settings > Network & internet > SIMs > Data usage (Android) to track consumption.
On a 5GB plan shared between two devices, expect the data to last 3 to 5 days with moderate browsing and messaging.
Frequently asked questions
Does hotspot sharing slow down my eSIM speed?
Yes. Expect speeds to drop 20% to 40% compared to using the eSIM data directly. The phone acts as a router, which adds processing overhead. With multiple devices connected, the bandwidth is divided among them. A connection that delivers 50Mbps directly may deliver 25 to 35Mbps through the hotspot.
How many devices can connect to my eSIM hotspot?
iPhone supports up to 5 simultaneous hotspot connections. Most Android phones support up to 10. The practical limit depends on your eSIM plan's bandwidth. With a 4G connection, 3 to 4 active devices is comfortable. Beyond that, each device gets noticeably slower.
Does hotspot use more data than regular browsing?
The data consumed per activity is the same whether used directly or through a hotspot. However, connected devices may run background processes (app updates, syncs, push notifications) that consume data without your knowledge. Disable automatic updates on all connected devices to conserve your plan.
