Problem with my dads phone

[kendafulp]

My mom had a s24plus and my dad had a s23 ultra. They wanted to switch so i did that for them i factory rest both phones got back their personal stuff like photos apps and accounts. Last thing i did was switch their sim cards each to the correct phone which I thought was a simple get the pin switch them and put it back in. They both are from the same carrier. The s23ultra sim is working just fine messages calls and mobile data. The problem is with the other phone the s24plus sim. It has messages and calls BUT mobile data isnt working. I tried switching them back the sim functions normally on other phones. And i tried putting a different sim on the s24plus and it worked just fine. So the problem is just specific to this phone and this sim when combined together is there any thing i can do??? Other than convincing my dad to change his phone number which he had for like 20 years because its not happening and is crucial to his work and connection with clients he has

Welcome to the forums. I would try a reboot. If that doesn't work contact the carrier. They may need to do something on their end.

As far as I know, you are right, what you did should have been seamless, but sometimes Murphy likes to show up and say hi.

Are you in the US?
How old is the sim card?
Possible needs a replacement or can go to settings>connections>mobile network>APN ( Access Point Names) tap 3 dots upper right corner reset to default
