New to Dual SIM iPhone and wondering how you can switch mobile data or cellular data over from one mobile data plan to another mobile data plan (one SIM Card to another SIM Card)? You are on the right page!

Here’s how you can switch mobile data in Dual SIM iPhone

1) Go to Settings > Cellular.

2) Tap on Cellular Data. Depends on how you label your plan / SIM Card – by default they are labelled as Primary and Secondary, but you can choose beween the two options. So choose between one of the two options to switch your mobile data into another SIM Card.

Tips for uninterrupted Internet in Dual SIM iPhone

On a Dual SIM iPhone where both SIM Cards are used (either 1 SIM Card with 1 eSIM or 2 SIM Cards) and both SIM Cards have internet / mobile data enabled, do this to get uninterrupted Internet.

1) Go to Settings > Cellular.

2) Tap on Cellular Data.

3) Turn on Allow Cellular Data Switching.

Once you are allowing cellular data switching, whenever one of the line does not have enough coverage or worst not available in certain areas, the iPhone will automatically switch over to the other line, so you’ll have uninterrupted Internet.
