Can I move my cell phone service just by moving my SIM to a new phone?

When you move your SIM, you keep the same cell phone service. SIM cards make it easy for you to have multiple phones so you can switch between them whenever you like. These phones have to be either provided by your cell phone provider or they have to be unlocked phones.

With unlocked phones, you can always switch your phone service between different phones as easily as popping out the SIM card and moving it.  You can also use different phone service plans in a single unlocked phone, say one for work and one for personal, by switching the SIMs.  The opposite of an unlocked phone is a locked phone.

In contrast, only SIM cards from a specific cell phone company will work in its locked phones. These phones were locked to protect subsidies, i.e. the amount that your cell phone operator subsidized to have you sign a contract with early termination fees.

    I have an iphone 5 with 16 GB and want to change to another iphone 5 with 32 GB. The 2nd phone has no contract nor SIM card. Can I not just take the SIM card out of the original phone and pop it in the 2nd one

      If it’s compatible yes

    If I switch my SIM card does it transfer all memory data, like apps and photos?
    I have to know because I’m getting a new phone soon and I’m going to transfer my SIM card into that phone. (I have an Android Motorola G phone by the way)

      If you transfer your contacts from your phone to your SIM card you can take your address book. But the SIM won’t stores your apps, photos or videos. You’ll have to back those up to something like Google Drive or Dropbox, and download them on the new phone.
