Ukrainians were explained why the physical SIM card needs to be changed periodically

Inside almost every smartphone or mobile phone there is a SIM card from the operator. The SIM card device is quite complex – inside there is a small processor, as well as permanent and random access memory. The memory stores the mobile operator's data for connecting to the network.

There are at least 3 reasons to change the physical SIM card every few years. Let's talk about them.

Connection problems

There are situations when the phone starts to glitch – lose the network in places where other phones do not experience problems. If your SIM card was released a long time ago, then perhaps changing the SIM card to a new one will eliminate these problems. The SIM card software also changes and improves, and very often this method helps to get a stable connection.

Getting a new SIM card is simple – just come to any operator office: the number remains the same.

Physical wear of the SIM card

Any SIM card has permanent memory, which stores various settings, as well as SMS and numbers. If there are problems with saving contacts, SMS and SIM card settings, it is possible that the memory is worn out.

Memory wear can also affect the quality of communication. By the way, it is better to change the SIM card once every 5 years to avoid possible problems, for example, a complete loss of communication at the most inappropriate moment.

New technologies

Cellular operators are constantly improving their communication quality. For example, if your SIM card was released 15 years ago, it may not support 4G. Also, operators can now accelerate 4G and improve the quality of data transmission – to take full advantage of such, it is advisable to replace the SIM card with a new one. When you receive a new SIM card, you also receive an updated menu from your mobile operator.

Virtual eSim

If the smartphone supports a virtual SIM card, it is better to use it. Firstly, such a SIM card will never fail, and secondly, you can add several phone numbers from different operators and switch between them. This function is especially convenient when roaming abroad – you don't need to physically insert the SIM card, just switch to the selected number.

By the way! If your smartphone often loses the network and calls are interrupted, you can try to wipe the contacts of the SIM card with an alcohol wipe. Oxidation may have occurred and contact occurs once in a while.
