The SIM card has enough memory to typically store up to 250 contacts, some of your text messages and other information that the carrier who supplied the card can utilize. Photos are not stored on SIM cards, so make sure they are backed up.
Does a SIM card store data? Yep, SIM cards do store data, like your phone's information. They can also show your data usage.
No. SIM cards do not store data.
Data that SIM cards contain include user identity, location and phone number, network authorization data, personal security keys, contact lists and stored text messages. SIM cards allow a mobile user to use this data and the features that come with them.
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.
And as you may have guessed, no phone number in your phone means no calling or texting. Losing these capabilities is only temporary of course. Once you reinsert your SIM card in your phone and get your signal bars back, everything will return to normal and you won't lose any data or information.

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.
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.
Remove your accounts, SIM and memory card
As part of the final preparatory process, you want to remove all your accounts configured on your device before doing a factory reset. A Factory reset will not remove your accounts from that device.
Take the SIM card out
The Subscriber Identity Module card stores information about you and your cell phone, including phone numbers, text messages, billing information, and data usage. When you sell your phone, the new owner will need his or her own SIM card so there's no reason to leave it in your phone.
The typical SIM card only contains about 128 to 256 kilobytes of user-writable data. This is just enough to store basic information such as your contacts' names and numbers and in some cases a small number of text messages You cannot increase the memory in your SIM card.
Regardless of the device you're switching from, don't switch your SIM card until the entire transfer is complete. Before you get started, you'll also want to make sure both your old device and your new device have at least 20% battery life.
Text messages are stored on your phone, not on your Sim. Therefore, if someone puts your Sim card into their phone, they will not see any text messages that you have received on your phone, unless you have manually moved your SMS's to your Sim.
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.
A SIM card is a pseudo-memory card, as it does have some memory inside. However, as you know now, that memory is used for storing a limited number of phone book contacts and SMS messages. The memory on a SIM card cannot be used for saving photos, videos, music, documents, or any other type of file.
If you remove the SIM card from your phone, your text messages should not be deleted from the phone, as they are typically stored in the phone's internal memory or on a memory card (if you have one inserted).
Changing your SIM card doesn't mean you'll lose your data. Your contacts, app, music, photos, and other data not stored on the SIM card will remain accessible. The only data that will be deleted is your old SIM card account information. Your Apple ID and iPhone settings are not affected.
When you have an unlocked phone, you can use any SIM card. Prior to the invention of 4G LTE, networks were split between GSM and CDMA operators. Now, since the introduction of 4G LTE phones, new iPhones and Android devices are compatible with both GSM and CDMA networks.
