after a week my call log disappears and i can’t see my calls from months ago is there a way i can get those back?

Hello! You call log will only show the last 100 calls. If you need more call history you can always contact your carrier.

Hello Lowk3yjayy1,

Thanks for reaching out to Apple Support Communities. Upon review of your post, it seems that you want to know how to increase the amount of time your call log is visible on your iPhone. We can see why you’d want this explained, so let us help from here! Whether your call log displays a list one day or thirty days old, you will see the last 100 calls only. That is the expected behavior for your iPhone.

Please let us know if you have follow up questions, so we can continue assisting. Take care!
