We have a phone call history of phone numbers. And all the phone numbers associated with all the text and all the text as well. What would be lost with a sim card change? Thanks.

The SIM does not store your call history or contacts. The average SIM only stores a limited amount of information about the phone (such as your mobile #). A SIM is not like an SD memory card and on the average only has a storage capacity not measured in megabytes but kilobytes instead. If you are concerned about potentially losing any information in the old handset, back it up to some online storage site.

Most phones have the ability to simply transfer the contents of the old phone to a new phone at no additional cost. The required tool for that is typically already installed in Android or Apple devices.

Bottom line, you will not lose any information as long as you keep this in mind.

We called CS for Consumer Cellular and they mentioned calls store on the phone and text stored on the sim card. It is an Android phone.

Like I mentioned, the SIM has very little storage space. Contacts, calls and text are stored in the phone's internal memory. As I mentioned, you can easily transfer that from the old to the new phone in a manner of minutes. The SIM is not the same as an SD card which has capacity of several megabytes, up to a terabyte in some high-end phones/devices.

The CS rep is confusing the 2 items. They are not the same thing, nor do they have the same capacity. The average CS rep doesn't have the personal experience as most members here at HOFO. I was a CS rep for At&t for almost 14 years and dealt with several dozen phones over that time frame. Originally when SIM cards were first introduced there was far less storage needed in the SIM as the amount of data stored was very minimal on the SIM.

Older phones only stored the 10 digit phone number and about the same # of characters for the contact's name. Most phones in the early to mid '90s could only store about 100 phone contacts which used to be on the SIM card. Today, many folks store multiple phone #'s, mailing address, email address and other pieces of data per contact, thus the reason the SIM cannot store that information.

In this case, it doesn't matter if you are using an Android or Apple device.

BTW: nothing personal about Consumer Cellular reps, but they are not the sharpest tools in the shed.

I have maybe 75+ text messages on my phone. Where are they stored such that a new sim card won't lose them? Thanks.

Perhaps not.

3. What is stored on a SIM card?

Despite the complicated name, it's basically your phone number. They can also store contact information, telephone numbers, SMS messages, billing information and data usage. Plus, your SIM will have a personal identification number (PIN) to protect against theft.

When I got a new phone a few months ago I got a new SIM card with it. My number stayed the same but during the setting up process you can be given the option to change everything to your new phone. This was from an Android to an Android.

It was suggested that our sim card was "cloned" and Google does find that. It would explain why our phone shows one text to a friend but 19 show in the online data for the account where we can see all numbers to and from for text.
November 24 we only sent one text to the friend but our data shows we sent 18. Not true.

We need to keep the text messages stored on our phone.

This article from Wikipedia may be useful. It talks about SIM cards in much more detail. https://en.wikipedia.org/wiki/SIM_card

How has no one asked this?
"What phone do you have?"
OP could have a 'feature phone' and many of these things may be on the SIM card.
