A SIM card is needed to send and receive SMS and MMS messages and to connect to the mobile internet.
What are the standards for SIM cards?
Today, three types of SIM cards are in use: broken out of plastic with the size of a Mini-SIM credit card, slightly smaller than the Micro-SIM and the size similar to the Nano SIM chip. These are the next generations of the same card, which differ mainly in size. Fortunately, subsequent versions of the standard are compatible with each other – an ordinary Mini SIM card after trimming can be inserted into the Micro-SIM and Nano-SIM slots.
Smaller cards placed in the appropriate adapter can be placed on the phone with a socket using the older standard, which was designed for larger cards. However, it is worth ensuring that before buying a new device you should equip yourself with a card of the right size or with the appropriate adapter.

You must also be careful not to buy a phone that uses CDMA technology instead of the GSM standard used in Poland based on SIM cards.
