Which SIM to use in the iPhone
As just mentioned, all newer iPhone models use the Nano-SIM (technically called 4FF cards) but in the second-hand market there are still more dated "melafonini" using Micro-SIM (technically called 3FF). In light of this I would say to make a brief summary and to see, together, which are the iPhone models that use the Nano-SIM and which, however, are stuck to the "old" Micro-SIM.
- The iPhone models that use Nano-SIMs are: iPhone 6s Plus, iPhone 6s, iPhone 6 Plus, iPhone 6, iPhone SE, iPhone 5s, iPhone 5c ed iPhone 5.
- The iPhone models that use Micro-SIMs are: iPhone 4s, iPhone 4.
How to insert a SIM in the iPhone
insert iPhone SIM, regardless of the model of "iPhone by" in your possession, you must take the metal paper clip included in the sales package: you can find it in the white card placed immediately under the device.
Not sure how to use the metal paper clip in the iPhone box? Don't worry, this is really a no-brainer. Insert the paperclip into the tiny hole that you find on the right side of the device and exerts a fairly firm pressure. You may need to tilt the tip of the paper clip slightly outward, then downward, to get the SIM slot to eject.
If you have lost the clip that is supplied by Apple, or in any case you do not have it at hand at the moment, you can also extract the "drawer" with a common metal paper clip (the ones used to hold documents together), you do not have to other than slightly distorting the tip outwards.
When the operation is completed, a click will signal the exit of the SIM "drawer". At this point, completely remove the SIM module from theiPhone (with your hands), fit the Nano-SIM into it making it match the shape drawn on the front and you're done.
To put the slot back into its slot, push it with your hands and apply some pressure. Be careful not to move the card.
After taking steps insert iPhone SIM, the card will likely be locked by a PIN. To unlock it and start using the phone freely, press the button Unlock that appears on the screen and enter the code of the card. Next, if you want to prevent the iPhone from asking you for the SIM PIN on every reboot, go to Settings iOS device (the gear icon located on the home screen), select the item Mobile phone (or on that Telephone, if you are using a version of iOS prior to 11) from the menu that opens and go to the section SIM PIN. At this point, move up OFF the option toggle SIM PIN and re-enter the card unlock code to disable the PIN request each time it is turned on.
Please note: if you are inserting the SIM in an iPhone that has just been purchased or has just been restored to factory conditions, before unlocking the SIM and using the phone you will have to complete the initial iOS configuration procedure. During this procedure - which cannot be completed without first inserting a card into the phone - you must choose the language in which to use the operating system and you must indicate your country of residence. Next, you have to connect to a Wi-Fi network, you have to choose whether or not to activate the location services and, if you have an iPhone with a Touch ID sensor, you have to configure the unlocking of the phone by fingerprint. After this step too, set an unlock code for the phone, choose to configure the terminal as a new iPhone and create or configure your Apple ID. In conclusion, accept the terms of use of iOS, configure Siri and confirm the sending of the usage data to Apple and the developers.
How to adapt a SIM for iPhone
At the moment you cannot go to a center of your telephone operator to request a Nano-SIM? If you have five minutes of free time you could "manually" fit your old SIM into an iPhone card. All you need is a pair of scissors, a little bit of double-sided tape, a line, an felt tip pen it's a PDF template to print.
To better understand what I am referring to, linked to this Web page and click on the item Download original PDF file which is located at the bottom to download on your computer a module that includes the schemes to adapt Mini-SIM (ie traditional SIM) in Micro-SIM and Nano-SIM and Micro-SIM in Nano-SIM. If the document is not downloaded but viewed directly in the browser, click on the icon of arrow or the floppy disk to start the download.
After the download is complete, print the PDF to a sheet A4 using the 100% zoom level (in order to respect the aspect ratio of the original document) and position the card in the correct place of the template using a little double-sided tape. If you need to turn a standard SIM into a Nano-SIM, place the card in the field MiniSIM (2FF) to NanoSIM (4FF); if you need to transform a standard SIM into a Micro-SIM, place the card in the field MiniSim (2FF) to MicroSIM (3FF), while if you need to transform a Micro-SIM into a Nano-SIM, place the card in the field MicroSIM (3FF) to NanoSIM (4FF).
Now, trace the points on the board to be cut using a line it's a marker, cut out the SIM with normal ones scissors (being very careful not to nick the chip) and use a nail file or of the sandpaper to file the edges of the card.
For completeness of information, I would like to point out that in the very first iPhone models, such as theiPhone 3GS (which by now we can consider a technological antique product) Nano-SIM or Micro-SIM are not used but the classic SIM (technically called Mini-SIM). The procedure to follow to install them on the smartphone, however, is similar to that seen for iPhone 4 and successors. In fact, you need to take the metal paper clip included in the package of the device and exert a firm pressure in the hole located in the upper part of the iPhone (not on the side, as in the most recent iPhones).
Finally, you need to extract the card slot, insert the SIM in its "drawer" and reposition everything. In short, the steps to be taken are always the same, nothing that requires particular commitment or who knows what knowledge in the technological field, you just need a pinch of patience and attention while handling the card.
