SIM cards, SIM types & how they work

SIM Cards

SIM stands for Subscriber Identity Module and comes in many sizes but usually: Nano, Micro and Standard. A sim card is like a computer only much much smaller. Your sim card tells your phone which network to use when calling, sending text messages, browsing the inernet, using apps, send pictures or videos etc...

Each sim card contains an International Mobile Subscriber Identity (IMSI) Number and authentification key. When you turn your phone on it gets your IMSI number from the sim card and sends this number to your network. Your network then checks to see if the IMSI number belongs to them. If it does, it can then monitor your use and bill you for the correct amount or check your texts, calls and data use against your allowances.

Different parts of a SIM Card

SIM Card different pins

You'll see that a SIM Card is split into multiple areas. Each individual area is called a Pin and each pin has it's own job.

  • Pin 1 is for connecting to the phone’s power supply
  • Pin 2 is to reset the SIM if required
  • Pin 3 provides the SIM with a clock signal for its processor
  • Pins 4 and 8 are reserved for future uses
  • Pin 5 is to ground the chip
  • Pin 6 can be used to communicate with an NFC enabled mobile phone
  • Pin 7 controls the interaction between the phone and the SIM

Different sizes of SIM cards

Standard or Mini SIM (15 x 25mm): The Standard SIM card is used in most of the older mobile phones, it was launched in 1996 and is used in mobile phones such as; BlackBerry Curve 9320, HTC Desire,Huawei Ascend P1 and Samsung Galaxy Ace to mention but a few.

Micro SIM (12 x 15mm): The Micro Sim card was launched in 2003 and is used in mobile phones such as; Apple iPhone 4, Apple iPhone 4s, HTC One S, LG Stylus 2 and Motorola Moto G4 Plus.

Nano SIM (8.8 x 12.3mm): The Nano SIM card was launched in 2012 and is the smallest of the 3 SIM cards. The Nano SIM card is used in most of the newest smartphones, such as; Apple iPhone 5 and all versions since the Apple iPhone 5, Samsung Galaxy S8, Samsung Galaxy S8+.

See our comprehensive list below 'Which SIM card does my mobile phone use' to find the SIM card you need for your mobile phone.

Standard SIM Card, Micro SIM and Nano SIM sizes

Introducing the Mulit SIM

SIM Cards

A Multi SIM card is a three in one SIM card which can be used in every type of smartphone or tablet. Most networks now provide Multi SIM cards. The size of the SIM card is definded by the plastic around it. The Multi SIM card contains a Standard, Micro and Nano SIM card within it. It makes financial sense to the networks, why pay manufacturers the cost of making 3 different types of SIM card when you can pay for one SIM card that contains all three.

If your mobile phone requires a Standard SIM card you can just pop the SIM card you recieve from your network straight in to your mobile phone.

If your mobile phone requires a Micro SIM card, just pop or cut the SIM card you recieve along the outer dashed/dotted line.

If your mobile phone requires a Nano SIM card, just cut or pop the SIM card you recieve along the inner dashed/dotted line.

How to keep your existing mobile phone number

Make sure you can switch network: Check with your existing network to make sure there are no cancellation charges if you switch network. These cancellation charges will usually apply if you are still within the contract time length of your current contract.

Choose your new SIM Only deal: Keeping your existing mobile phone and taking out a SIM Only contract is a great way of saving money, in some cases it could half your current monthly cost. We have hundreds of SIM Only deals for you to choose from, from all the networks and retailers in the UK.

Get a Porting Authorisation Code (PAC code): Once you have decided to leave your exisitng network and choosen your new SIM Only deal, you need to call your existing network and ask them for a PAC Code. If you phone your existing network up, Ofcom have insisted that they have to give you your PAC Code immedialety. At this stage your network may try to tempt you to stay with them, offering you a better deal.

Give your PAC code to your new network: If your existing network has been unable to tempt you to stay with them, call up your new network and give them the PAC Code you got from your exisitng network, once you have given your new network the PAC Code, it usually take 24 hours for your mobile phone number to be switched to your new network.

SIM ONLY FAQs

There are three different SIM card sizes: Standard also know as Mini, Micro and Nano. There are several ways to find the type of SIM Card your mobile phones uses; you can visit our SIM Card Finder, look on the packaging your phone came in or the internet for specifications on your mobile phone. However here are some general tips that might help you.

  • Multi SIM can be used as a standard, nano or micro SIM card. Simply pop out the SIM size you need.
  • Standard SIM will fit mostly older phones.
  • Micro SIM will fit most Android or Windows phones (including iPhone 4/4S, Samsung Galaxy S4 and Samsung Galaxy S5)
  • Nano SIM will fit most iPhones (eg. iPhone 5 and iPhone 6 Plus)

A SIM only deal offers a package of minutes, texts and mobile data for a monthly cost, much the same as a traditional mobile phone contract. The difference, however, is that you don’t get a new handset; you get the SIM…only.

If you are looking for a SIM only deal with your current network, they already have all your details so a credit check is highly unlikely.

You'll have to pass credit check if your looking for a monthly rolling contract or a 12 or 24 month SIM deal contract with another network. If you fail a credit check there are some great Pay As You Go SIM only deals on the market, the only possible disadvantage with this, is you have to regularly top up.

Sometimes the lesser know names offer the best value for money in allowances (text, calls and data). The lesser know networks use the bigger names networks, so the quality of the signal is no different, as an example GiffGaff and Tesco use the O2 network, Virgin uses the EE network.

SIM Only deals are ideal if your happy with your current phone. A large percentage of your monthly bill will actually go towoards the cost of the handset.

As an example, on a SIM Only deal you could get 8GB of data and Unlimited calls and texts (allowances) on EE for £23, similar allowances with the latest phone could cost upwards of £45.00 not including an upfront cost of over £100

If you take a 1 Month SIM Only deal, it also gives you the ability to change networks regularly to take advantage of any offers.

We think we do, we have all the networks and all the largest retailers, giving you hundreds of SIM Only deals to choose from, for phones, tablets and wifi. Below is a current list of our existing Network SIM Only deals.
