SIM

The small microchips known as “subscriber identity modules” or SIM cards that are required for mobile phones to log on to a phone network will soon be 25 years old. While mobile phones and network technology have progressed in leaps and bounds, SIM cards are still lodged in handsets.

If you frequently switch SIM cards on your phone, you should consider using a call forwarder app. What a call forwarder app does is forward all the calls from your old device to the new one. So whether you have changed your phone number or the phone itself with a new SIM card, you will still receive calls that were for your old number. While there may be a number of apps that help you forward calls on an Android phone, here we have chosen some of the best ones for you.

TechCrunch reported about Apple’s new SIM card, Apple SIM. With this new SIM card, you will be able to change carriers with ease instead of having to buy a new SIM card if you want to switch between AT&T, Sprint, or T-Mobile. Now you just need to go through the settings menu on your device and select your carrier.
