Part 2 > Q122: SIM Card > Caution point regarding SIM card adapter
Q : The Galaxy S4 I purchased uses a different size SIM card to my existing device.
What should I do for this problem?
A : If you have a SIM of a different size to that used on the S4 please contact your SIM provider / Network operator to request a
new SIM card for use with your Galaxy S4.
Samsung does not make SIM card adaptors nor recommends their use with its devices.
Note: If you try to use a "Nano" to "Micro" SIM card adaptor with your Galaxy S4 and this has resulted in the reader
being damaged the device is classed as OUT of WARRANTY.
