Yep, SIM cards do store data, like your phone's information. They can also show your data usage.
Although a SIM card is of a similar size to the high-capacity memory card you use in your camera or smartphone, the average SIM typically only holds a mere 32 to 128 kilobytes of data. But, that is enough to store important data like your contacts and subscriber information.
In summary, when you put your SIM card in another phone, the only data that will be transferred is your own phone number and possibly a few text messages and contacts saved on the SIM card. The rest of your data, including photos, videos, and other files, will remain on your old phone.
Remove SIM and SD cards
If you're going to keep the same phone number, you may be able to transfer your SIM card to your new phone. If you're not going to reuse the SIM card, destroy it. If your phone has an SD memory card for storage, remove it.
Does taking out your SIM card delete everything? The short answer is: nope. The shorter answer is: no. Taking out your SIM card will not delete all of your data.
The SIM card memory is not enough to save your pictures. It stores a small amount of info including: your phone number. some contacts and text messages.
The SIM has some stuff embedded into it that when activated by your provider allows your device to access their network. Switching out the SIM will require the new one to be activated before the device can access the providers network but that should be all, everything else should still be there.
3. Remove Your SIM Card and MicroSD Card. You obviously don't want the next owner to have your SIM card, so go ahead and remove it from the phone. While you're at it, take out the microSD card too if you happen to have one installed, and insert it into your new phone to access your stored files.
Plug in both phones with a cable if using one, or to charge if sending data wirelessly. Open the Smart Switch app on both phones, the app can be downloaded from the Google Play store if it isn't pre-installed. Go to Settings > Smart Switch on the new phone. Select Transfer data and click on Continue.
Can I just buy a phone and put my SIM card in it? Sort of, yes… the phone just needs to be SIM unlocked (network unlocked) and that's really all. Either a factory unlocked phone or a phone from a cellphone carrier that has been unlocked.
Photos are not stored on SIM cards, so unless she backed up the phone or synced photos to iCloud there is no way to recover them.
Additionally, SIM cards store two passwords: your Personal Identification Number (PIN) and your Personal Unblocking Key (PUK). The PIN code is required to unlock the SIM card when inserting it into a new phone or after a reboot.
SIM cards store data for the phone user, containing personal information like phone number, contact information, text messages. SIM cards also act as storage devices that hold Service Provider Name, Mobile Subscription Identification Number, International Mobile Subscriber Identity or IMSI, etc.
Go back to Settings and tap General > Transfer or Reset [device] > Erase All Content and Settings. If you turned on Find My [device], you might need to enter your Apple ID and password. If your device uses eSIM, choose the option to erase your device and the eSIM profile when asked.
Whether you plan to trade in your old Android phone for a discount on your new phone, sell it on eBay, give it away to a friend, or drop it off for recycling, you're going to want to wipe it of all your data first by resetting it to factory conditions. Luckily, that's pretty easy to do.
No. SIM cards do not store data.
In fact, all text messages are saved on Android phones by default. Therefore, if you only have a SIM card, you cannot see the text messages saved on the phone. If you want to save them on the SIM card or SD card, you have to manually move them to the SIM card one by one yourself.
Nothing special will happen. After putting in the SIM card, you can use mobile data or transfer the contacts on it to your new iPhone.
SD cards, with their small size but powerful storage capabilities, are a great way to move photos between devices and to new devices. You can easily move your pictures and other files onto an SD card with a PC or Mac, and even an Android phone.
SIM cards can come in various data capacities, from 8 KB to at least 256 KB. All can store a maximum of 250 contacts on the SIM, but while the 32 KB has room for 33 mobile network codes (MNCs) or network identifiers, the 64 KB version has room for 80 MNCs.
To be extra safe, it's a good idea to remove your SIM card, which may contain your phone number, security information and billing info. To remove, locate the SIM tray (usually on the right side of your device) and insert a paperclip into the hole to pop out the tray.
