A SIM card is a chip used in mobile phones to identify the user to its mobile carrier. Blank SIM cards, on the other hand, are different from normal SIM cards as they don’t have any personal data of the users, and are free of information. Their main purpose is to be used in either new phones or as replacements in the old phones. They allow you to change the phone number, back up your information, or clone your existing SIM card for dual functionality. If you want to back up or copy the information from your old SIM, make sure the blank SIM card comes with sufficient memory to copy all the data.
Compatibility of the blank SIM card
Mobile handsets have different slot sizes to accommodate the SIM card. Thus, before purchasing a blank SIM card, ensure that its size is compatible with the handset you will use. Most people who buy a blank SIM card are those whose original SIM card is either damaged or has become unusable. Before buying this type of SIM, check your device’s user manual to see what size SIM card it is compatible with.
Apart from size, there is one more limitation you may face while buying a blank SIM card. Some mobile phone companies enable their handset to work with some specific SIM cards only, which are usually based on brands. Ergo, it is recommended to check the software/electronic compatibility of the blank SIMs with your phone, otherwise, it will make the card useless. Also, this kind of SIM card may have a phone number that will become your device’s number. In such a case, choose the number wisely so that you can easily remember it. The number gets activated when your SIM card gets active.
How to use a blank SIM card?
Using a blank SIM card is like using a digital clean slate. There is no information on the card, that’s why the users have to re-enter their cell phone account details. To make such SIM cards worthy of use, you may require a SIM card reader/writer to transfer or modify the information from the existing SIM card to the empty one. Thus, contacts, text messages, and other such information can exist on both SIM cards.
Cloning a SIM cards
By cloning, you can make a blank SIM card the exact duplicate of the original one. The information on both the SIM cards would be the same, including the phone number. After the cloning process is done, the user may use the cloned SIM card to make calls and send texts, and the charges will be billed on the original SIM card. However, it is important to note that the cloning of SIM cards is illegal in most countries. With that in mind, a blank SIM card shouldn’t be obtained for this purpose. It is okay to clone a SIM card for educational purposes. If you need that sort of thing, we have a step-by-step guide for cloning the SIM card.
Where is a blank SIM card available?
Blank SIM cards are usually cheap and available online on many websites. They can be purchased from cell phone company websites too. If you are buying blank SIM cards for cloning, you should undoubtedly remember not all SIM cards are clonable. As a reminder, only the COMP128v1 version SIM cards are. The other versions have secure firmware which prevents cloning as no company wants to keep its users a duplicate/cloned SIM card with or without authentication.
Decided to buy one for the carrier in case your original SIM card is lost or damaged? Then the original SIM card will be voided by the company as soon as your blank SIM card is issued and activated.
A blank SIM card is like an empty key you can mold and program on a whim, based on your needs. Remember that blank SIM cards shouldn’t be cloned, as no mobile operator allows this. These SIM cards are generally issued by the telecom operator to you in case you have lost or damaged your SIM card. Most blank SIM cards provided by the company are preprogrammed. However, there are many blank SIM cards available in the online market that are writable and used as prototypes, dummy SIM, or backup purposes, among others.
