How to Cut a Sim Card & Make A Nano-Sim for iPhone And Android

We are using sim cards in our daily life. It’s like we cannot imagine our lives without sim cards and without phones. Well, our world is growing in technology very fast, as time passes we are developing systems that have more capacity but requires less space. In the same manner, experts deal with the sim cards. We are mainly focused on cutting the sim card to the Nano size for an iPhone, but prior to that, I would like to share some elaborated information about sim cards, their sizes and a little bit about history.

What is a Sim card Stands For?

Most of us are unfamiliar with the fact that to which word SIM stands for, so SIM is actually an abbreviation of subscriber identity module or subscriber identification module.
It is an integrated circuit that is intended to secure the international mobile subscriber identity (IMSI) and its related keys. This is useful to identify and authenticate the subscriber on mobile telephony devices like a computer or mobile phone.

 Which Can Operates The Sim Card?

Sim cards can be used for saving the contact information. It can be used on mobile phones like GSM phones, CDMA phones, they are only needed for new LTE capable handset. Moreover, some computers do have the capability to operate a sim card as it is operated in the phones. Some other phones like satellite phones also use a sim card. Other than this there are some cameras and smart watches in which sim cards can be used easily.

Sim Circuit

It is the part of the function of UICC i.e. universal integrated circuit card, physical smart card, which is usually made of PVC embedded with conductors and semiconductors.

Portability

Sim cards are easily portable. These are transferable between different mobiles. You can carry it anywhere within the range of mobile and most importantly within the range of the service provider, the sim network you are using. Like every country has its own specific range. You cannot use sim of one country in the other country except a few ones that give you network access by paying some additional fees.

Earlier Times Sim Card/history Of The Sim Card

European telecommunication institution was the first to specify the sim card with the specification number. So the question is why there was the need to specify a sim card. This is actually that sim card specification number describes the behavior of sim card logically and physically.

Which Can Operates The Sim Card

Every sim card has its own personal identity. This identity is called as its serial number. This is ICCID, international mobile subscriber identity number (IMSI), security authentication and ciphering information, temporary information related to the local network, a list of services a user is provided with, and two passwords: a personal identification number (PIN) for ordinary use, and a personal unblocking code (PUC) for PIN unlocking.

ICCID

ICCID is the identifier of the actual SIM card itself – i.e. an identifier for the SIM chip. Nowadays ICCID numbers are also used to identify sim profiles, and not only physical SIM cards. Each SIM is internationally identified by its integrated circuit card identifier (ICCID). ICCIDs are stored in the SIM cards and are also engraved or printed on the SIM card body during a process called personalization.

International Mobile Subscriber Identity

SIM cards are identified on their individual operator networks by a unique International Mobile Subscriber Identity (IMSI). Mobile network operators connect mobile phone calls and communicate with their market SIM cards using their IMSIs. The format is:

  • The first three digits represent the Mobile Country Code (MCC).
  • The next two or three digits represent the Mobile Network Code (MNC). Three-digit MNC codes are allowed by E.212 but are mainly used in the United States and Canada.
  • The next digits represent the mobile subscriber identification number (MSIN). Normally there are 10 digits, but can be fewer in the case of a 3-digit MNC or if national regulations indicate that the total length of the IMSI should be less than 15 digits.
  • Digits are different from country to country.

  • The Nano-SIM measures 12.3 × 8.8 × 0.67 mm and reduces the previous format to the contact area while maintaining the existing contact arrangements.
  • It is only 0.67mm thick, its length is 12.30mm and width is 8.80mm only.

So it’s easy to cut your sim card by yourself into micro sim dimension. If you are more daring you can also cut your micro sim card with ruler and pair of scissors easily, But I don’t recommend this I am strongly against this Because if you don’t cut it properly you may face some abnormalities in your sim card or it can damage the handset as well.If you are switching to Nano sim card, it is not recommended to cut it yourself. This is because of the fact that Nano sim cards are slightly thinner than the micro sim card and you cannot cut it properly at home if you don’t own the sim cutter. We, Will, Does not Discuss the Process Of Change on Each Mobile But Only For The IPhones.

How to Cut a Sim Card to Nano Fit For an iPhone

Well Nano fit in the iPhone started in 2012 with the invention of iPhone 5. IPhone 5 was the first model in which Nano sim card was used, now all IPhones and IPads use Nano sim cards. This is the advancement that you can fit the sim within the smaller area but it can be a bit problem for the people while switching their devices.

The technology is same as in the standard sized sim or in the micro sim. The same metallic part is installed in Nano sim but the difference is that the extra plastic around the sim is cut off, this features enable us to settle Nano sim in even smaller space. You can cut it at home but if you don’t want to take a risk as above, so you can order a Nano sim on exchange policy. To cut your SIM card down to Nano-SIM size you need the following equipment:

Requirements- What You Need?

  • Standard or micro-SIM card
  • Nano-SIM card (for measurement)
  • Pencil
  • SIM ejector tool (or paperclip)
  • Small pair of straight scissors
  • Nail file
  • Once you have all these to hand it’s time to get started.

The Procedure of Cutting The Sim

First, if you have a standard or micro sim card, you will need a Nano sim, as a sample, for the exact measurement. Place the sample sim over the sim you want to cut. Then mark the boundaries using the pencil. The step ahead needs more care. Be caution. It is better to trim the sim card a little bit and then proceed further. Ou can cut it using the pair of nail scissors. We use the smaller pair for more accuracy. Then you can make the boundaries smooth using the nail filer. It’s better to trim it slightly large and squeeze it in, rather than cut off too much and it be wiggling around inside the SIM card slot. Trim off the corner manually.
