Buy a phone of your choice
It is of utmost importance that you must buy a cell phone of your choice. You must think of the features you are looking for in a mobile phone and decide your budget. If you do not want to buy the cell phone on cash, you must consider the packages of different companies and choose the one that is best suitable to you. Remember that the days when the SIM card was of a standard size has passed and now SIM cards come in different sizes, depending upon your cell phone.
Know the SIM card size
If you have purchased a phone that was introduced a few years ago, then you will not have any trouble in obtaining the SIM card of your desired size. Note that the SIM card of these phones is of standard size. However, if you have bought a recently introduced phone then you must know about the size of the SIM card. It would be mentioned on the phone box or feel free to ask the shop owner. For example, iPhone 5 requires it users to obtain a Nano SIM card.
Find the spot
After you have purchased the SIM card of your choice, you must now insert the spot to insert it into your phone. Note that the SIM card will only be activated, after you have placed it in the proper spot. For most of the phones, all you have to do is to remove the back cover of your phone and battery and look for the spot underneath your battery. If you are using iPhone, then you must take a look at the user manual as it demands the user to insert a pin into the space provided and only then, the SIM jacket comes out.
