Data Roaming

[InsaneVaas]

Hi members, so I'll be travelling to the US tonight and I have purchased an e sim, however it requires me to turn on the data roaming option to use it. Now the question is, I already have another sim which is my primary sim and I don't want to disable it while I am travelling, however I cant see an option to turn off data roaming for a specific sim like we used to earlier, so will changing my esim to primary sim and then turning the data roaming on will work the same? As I don't want hefty charges to be added to my main sim while I am travelling.

Thank you.

Hi InsaneVaas,

Yes, your plan can work, but there are better ways to ensure your primary SIM does not incur  roaming charges while using your eSIM for data roaming in the U.S.

Turn Off Data Roaming for the Primary SIM: While you mentioned the option to disable data roaming for a specific SIM isn’t visible, double-check:

Settings > Connections > SIM Manager (or Mobile Network). Locate your primary SIM and turn off its Data Roaming.

Set the eSIM as the Primary for Data: Go to Settings > Connections > SIM Manager. Set the eSIM as the Preferred SIM for Mobile Data. Turn on Data Roaming only for this eSIM.

This ensures that all mobile data usage happens through the eSIM, preventing your primary SIM from using data.

Disable Mobile Data on Your Primary SIM as an extra precaution. In SIM Manager, disable Mobile Data for your primary SIM. This ensures it won’t accidentally use data even if roaming is turned on.

Thank you.

Thank you for the response. I'll follow all the steps, however where you mentioned that I should disable mobile data for my primary sim as an extra precaution, I cannot find that option in Sim manager. It just asks me to disable the entire sim I am assuming as you can see here. Thank you.
