Both SIM cards need to have unique numbers so it is NOT possible to have dual sim cards with the same number. This is because your number is linked to one unique SIM card and cannot be divided at the moment. This means you won't miss any incoming calls or texts on one phone number while the other number is in use.
Can I use a duplicate SIM card?
No, from a number of perspectives. Each card has a unique “burned-in” serial number called an Integrated Circuit Chip ID (ICCID). It cannot be legally cloned. Far more importantly, cloning a SIM card is illegal and unethical - depending on your purpose of doing so.
What happens when you clone a SIM card?
Though the techniques are different, the end result of SIM swapping and SIM cloning is the same: a compromised mobile device. Once this happens, the victim's device can no longer make calls or send and receive text messages. The attacker in turn can use the acquired SIM for a variety of malicious purposes.10 Oct 2019
Can I use 2 SIM cards in 2 phones?
You can not use same sim number on two mobile simultaneously. As when you register on gsm or cdma network with sim card. You can not register with same sim card number on same gsm network. Sim card is used to get network.
Can you clone a SIM card and use both?
When you put the cloned SIM card into another mobile phone, it will work. In the future, when someone calls you, both phones will ring, but you can only answer from one phone while the other will fail to be answered. Also, if you make two calls at the same time, only one of them will connect successfully.18 Oct 2021
Can I use a duplicate SIM card in another phone?
Yes, it's possible. The phone number (MSISDN) is not on the SIM, instead an identity called IMSI is used for all operations in the radio network. A mobile operator can associate a single MSISDN to multiple SIM cards, each having a different IMSI and cryptographic authentication secrets.Yes, it's possible. The phone number (MSISDNMSISDNThe MSISDN is used for routing calls to the subscriber. The IMSI is often used as a key in the home location register ("subscriber database") and the MSISDN is the number normally dialed to connect a call to the mobile phone.https://en.wikipedia.org › wiki › MSISDNMSISDN - Wikipedia) is not on the SIM, instead an identity called IMSIIMSIThe international mobile subscriber identity (IMSI) /ˈɪmziː/ is a number that uniquely identifies every user of a cellular network. It is stored as a 64-bit field and is sent by the mobile device to the network. An IMSI is usually presented as a 15-digit number but can be shorter.https://en.wikipedia.org › wiki › International_mobile_subscriInternational mobile subscriber identity - Wikipedia is used for all operations in the radio network.

What happens if you duplicate a SIM card?
Each SIM card is unique, with a unique ID. This ID is mapped to your mobile number. So when you get a “duplicate” SIM, it's not really duplicate - but the network is set up to recognise it and allocate your number to the new SIM ID when you activate the new SIM in your phone.
