Speed is dependent on coverage, congestion, or prioritization of the local carrier.
If you are experiencing slow network speeds, please check if you have met all the requirements from your eSIM installation page, and proceed as below:
Set the device to 3G temporarily
iPhone Settings-> Cellular -> Select eSIM -> Voice & Data -> Select 3G
βAndroid Settings -> Cellular -> Select eSIM -> Preferred network tyep -> Select 3G
βToggle the airplane mode on and off
βTurn off Phone and On
β
In case your eSIM supports more than one network, you can also try to select a different network than you are currently connected to, in order to see if it provides a better service.
