Or, if the thief is someone close to you and directly interested in your private life, without an active SIM PIN, he or she might be able to also listen to your voicemail or read your new messages.

SIM card protection. You can lock and unlock each SIM card you use on your device with a PIN (Personal Identity Number). When a SIM card is locked, the subscription linked to the card is protected against misuse, meaning that you have to enter a PIN every time you start your device.
To protect your SIM card from others using it for phone calls or cellular data, you can use a SIM PIN. Then, every time you restart your device or remove the SIM card, your SIM card will automatically lock and you'll see "Locked SIM" in the status bar.
The reason many network providers SIM lock their phones is that they offer phones at a discount to customers in exchange for a contract to pay for the use of the network for a specified time period, usually between one and three years.
Lock your phone number with your service provider

This type of fraud is easy to execute and does not require any code, but it has devastating effects on victims' lives. A SIM card swap is a gateway fraud; scammers can easily hijack your phone number — and then steal your identity.
Scammers don't have to gain physical access to your phone in order to access your SIM card. Instead, SIM swap scams occur when fraudsters pose as you and trick your phone carrier into providing them with a SIM in your name.

SIM jacking or SIM swapping
Finally, SIM jacking, also known as SIM swapping or SIM hijacking, is a form of attack that involves the hacker accessing the victim's mobile device in order to take control of their SIM card. This is done by sending spyware code to the phone to break into the device.
The best way to quickly check whether a mobile phone is locked or not is to slip the SIM card out, and put in one from another network. If it can make calls, send texts, and connect to the internet, that means your phone is unlocked. Just make sure that the two SIMs don't actually connect to the same network.

If you're noticing unusual activity on social media accounts, that may be the result of SIM card hacking. Hackers may use SIM swapping to get into your social media accounts to impersonate you and scam your friends or family members for money.
To perform a SIM card hacking through a SIM card swap, a hacker will first call up your phone provider. They'll pretend to be you and ask for a replacement SIM card. They'll say they want to upgrade to a new device and, therefore, need a new SIM. If they are successful, the phone provider will send them the SIM.
Excess water, spraying, splashing, or submerging can be enough to damage a physical eSIM and prevent it from working. Spillage with corrosive or hot liquids also risks damaging a SIM card if they leak into the SIM tray.
No. SIM cards do not store data.
The short answer to this is yes. It's absolutely possible for someone to clone or even hack your SIM card. However, it's not that common – in fact installing spyware onto a victim's device is a much more common practice used by hackers.
According to TRAI consumer handbook, a sim card is deemed to be deactivated in case of non-usage for over 90 days (about 3 months). The non-usage here means zero incoming or outgoing calls/messages, no data sessions, no use of value-added services, and any related payment.
If your phone has a SIM card, it may store your personal information. Remove the SIM card. If you're going to keep the same phone number, you may be able to transfer your SIM card to your new phone. If you're not going to reuse the SIM card, destroy it.
