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 percent battery life.
Does Smart Switch need to be installed on both devices or only the new one? For Android devices, Smart Switch should be installed on both devices. For iOS devices, the app only needs to be installed on the new Galaxy device.
Items that cannot be backed up with Smart Switch
Contacts: Contacts saved on the SIM card, social networks (Facebook, Twitter, etc.), Google accounts, and work email accounts are excluded.
Your phone number follows your SIM card
This means that whatever phone you put your SIM card in will then have your phone number – as long as it's unlocked, of course.
In most cases, you can take a SIM card out of one phone and put it into another, and the new phone will work for calls and texts like the original one had. However, this can depend on the exact model of the phones, the way your phone company authenticates devices, and if the phones are locked.
No. SIM cards do not store data.
If you buy a new phone, Google makes it easy to transfer most of your data, letting you pick up where you left off. However, text messages won't automatically be transferred to your new phone. So any important texts you have from family, friends, doctor offices, or other sources will be lost.
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.
If you've gotten a new SIM card and a new phone, you should still remove your old SIM card. Keeping it inserted means that anyone who calls your old number will still make your old phone ring. Removing the SIM card will disable your ability to make calls, use mobile internet, and send or receive SMS text messages.
But people seem to forget (or not know) about wiping the phone's internal memory. That's where we found data on the five phones that still contained some. Removing the SIM card stops the phone from communicating with the network, but doesn't erase the email and contact lists already on the phone.
Turn off your phone. Locate your SIM-eject tool. If you don't have one, use a small paperclip. Insert the tool (or paperclip) into the small hole next to the SIM tray and push gently but firmly until the tray pops out.
You'll still have your contacts, messages, app and even your wallpapers. Find out more about what happens when you switch your SIM card via our guide. One thing that will be removed is your phone number, since that information is tied to your individual SIM card.
SMS messages and contacts
Entries that contain multiple phone numbers and additional phone numbers are usually not stored on the SIM card.
In layman's terms, a SIM (Subscriber Identity Module) card is a tiny, portable memory chip that stores information about you as a cell phone user. On it, there's a seventeen-digit code that designates its country code of origin, the system carrier (such as AT&T or Verizon), and a unique user ID.
On Android, texts are stored directly to the device that can be backed up to Google Drive or Google Drive Samsung Cloud for a Samsung device. Some phones allow you to save texts to the SIM card memory at least temporarily for the purpose of transferring cards between phones.
Back-up Your Data
Your data is precious, and whether it is old photos or your favorite music, you will want to make sure it is there on your new phone! There are several ways to do this, and it all depends on what device you have. In general, you can find the Back-Up / back-up & reset option in your settings.
Your new Android phone will automatically install all available apps from the Google Play Store again. Unfortunately, some apps will remember you, but some will need you to log in again.
Secondly, unless you're planning on switching phone numbers too, you need to take the SIM card out of your current iPhone and put it into the new one. The SIM card is a small data chip that carries your phone number and cell carrier account information.
