Can you increase the length of days of call log? One week is not enough

Call Logs in the "Recents" is not time-bound. It is the number of calls made and received.

You only have the last 100 calls in the call log, if you want more contact your carrier and ask for a detailed itemised bill for the period that you are looking for.

Just to clarify, it's important to understand that a single SIM card can actually be used across multiple devices. This means that you can make and receive calls from any device, including Android devices.

All the call history associated with that SIM card is consolidated in one central location: your trusted carrier. It's worth noting that your carrier will bill you based on this consolidated information. Therefore, if you need a comprehensive breakdown of your usage, I would recommend reaching out to your carrier and requesting a detailed itemized bill.

By doing so, you'll have a clear overview of your usage across all the devices you've used with that SIM card, ensuring transparency and accuracy in your billing.

Check on your carrier's website, most of them will have a page with your call logs that will go back much farther than the 100 call limit of the phone.
