What is a Sim Network Unlock Pin?

A“Sim Network Unlock Pin (NUP)” or“Network Unlock Code (NUC)” will remove the carrier lock built into GSM mobile phones by services providers to restrict the use of these phones to specific countries and/or networks. These are usually referred to as "Network (NCK)" or "Service Provider (SPCK)" locks and can be removed using the corresponding unlock codes, which are unique to each phone depending on its IMEI.Typically, a locked handset will display a message if a restricted SIM is used, requesting the unlock code. On recent phone models running Android software, the phone will display a message saying “SIM network unlock PIN” or “Enter Network Lock Control Key” if network locked. Windows phones will display the message, “This SIM card can only be used on specific networks".Unlocking the phone is universally legal so there are more reliable services like https://www.unlockradar.com, that will unlock your cell phone so you can use it with other carriers.The unlock code is verified by the handset and is generated by the manufacturer, typically using an algorithm such as a one way hash or trapdoor function. Sometimes big telecom providers change the original factory unlock codes as an extra layer of security against unlocking services. For various big brands such as Samsung and Motorola there is no algorithm but just a random code generator where the unlock codes are programmed in the phone itself and then saved in a big database managed by the manufacturer. The unlock companies like Unlockradar have access to these databases and that is how they can deliver unlock codes to their customers.

I just put my old SIM card in my new iPhone and it works fine, but AT&T is telling me that I need to use the new one that came with the new iPhone, why?

I believe that your IPhone 5 works well on 3 G networks and your new IPhone 6 works best on 4 G networks.So the old SIM card may work fine in the new phone but is unable to communicate or detect WiFi or to activate Bluetooth .Do you use these functions or services? WiFi is very useful to you when you need to access the internet. Some places provide free access to the internet, mainly in Malls, or food and beverage providers.The new SIM card that came with the new phone, has been configured, such that you will be able to utilize the full functions of your phone. Your phone number is attached to your new phone through the New SIM card. You can Google IPhone 6 for details of the phone.So, do worry about charges or the government spying on you, unless you are a Person of Interest, being seek by the CIA, FBI, NSA or the Homeland Security.Phone charges were agreed by yourself when you sign up or when you bought the IPhone 6.That being said, charges incurred by your usage of your IPhone for downloading of data or making Long Distance calls are chargeable by the Service provider or phone companies.Hope the above explanation has been useful to you.

Can we use a 4G SIM card in a 3G smartphone?

A SIM card is not at all connected with the technical features of a phone. The SIM card is simply a sort of ID card: it identifies you to the device and the network by giving your unique subscriber ID. It does have some storage capacity, where you can store, say, your contact numbers. It’s a legacy feature for most people now, because smartphones have much more space for storing contacts and other info, and they’re much easier to sync with other software, etc - old featurephones did not have such luxury, so people used to store that information on SIM cards.Apart from that, your SIM card does nothing else.The speed of data access relies on two things: your smartphone and your service provider. Every mobile phone does have a radio module that is responsible for talking to the network. It is this piece of hardware that either can or can not use latest communication technologies: if the phone does not support 4G, you will not get that speed whatever you try. Many smartphones today do support 4G, even more support LTE (a variation of 4G), so that shouldn’t be an issue.The carrier can also limit your speed: after your phone identifies with your SIM card ID, the carrier can look up what type of access is available to you (what option did you purchase) and let the phone use only the access speed you actually paid for. That means that your very fast 4G phone will use 3G if your contract with the carrier states that this is the speed you’ll get from them.If the phone is incapable of using the speed you’ve subscribed to, the network will switch to the best available option for that phone.To conclude: swapping SIM cards in and out of phones will transfer only your subscriber ID and data that you might have had stored on the SIM card, but it will not affect the speed of connection or the data/applications you have on the phone (for that you have other ID, such as Apple ID or Google account). The only issue here is that there are three different sizes of SIM cards, so you might have to cut the SIM card to size or use an adapter if the SIM is too small.
