Can You Have 2 Phones with the Same Number? Pros, Cons & Options

A phone with 2 working SIM cards will not surprise anyone. Phones with dual SIM cards are a part of modern people’s lives, where users can have two numbers on one phone. Why is this necessary? Primarily for work or travel.
But can you have 2 phones with the same number? This scheme seems a little more complicated because the SIM card is issued in a single copy, and you cannot get a copy of it.
However, there are several ways to use one number on two phones at once. Read the article and find out about these ways to implement them next time.
Why Would Someone Want 2 Phones with the Same Number?
The first reason for using the same number on 2 phones is to eliminate the risk of losing the phone number if one of the devices is lost. In addition, this scheme allows you to clearly separate work and personal life, keeping in touch with clients and loved ones from the same number.
Travelers, for example, appreciate the opportunity to stay connected by changing their device depending on the situation β whether it is a business smartphone at a hotel or a secure device on the road that they do not mind losing.

Can You Have 2 Cell Phones with the Same Number?
Can you have 2 different cell phones with the same number? As you know, one phone number can be linked to one device since the SIM card for the number is issued in a single copy by the mobile operator. However, today you can bypass any restrictions and find out if your carrier supports services such as MultiSIM or the USA eSIM. You can connect the phone number to several devices at once and use it at the same time.
*Note: In countries with more advanced telecom infrastructure, this feature has already become the norm, while in others, it is not yet available or access is limited.
What Technology Allows This
The MultiSIM service allows you to connect one SIM card to multiple devices. eSIM makes it possible to use the same number on different smartphones with technology support.
Some carriers also offer cloud solutions where calls and messages are synchronized over the Internet. It all depends on what technologies your carrier and your devices support.

Methods to Use One Number on Two Phones
Now, letβs discuss in more detail the methods that will help you use one number on two phones at the same time.
Using Dual SIM and Twin SIM Options
As mentioned above, some mobile operators offer MultiSIM. This service involves using one mobile line, and, accordingly, one number on two or more SIM cards. This is convenient if you want to receive calls and messages on different devices, such as a smartphone and tablet.
How it happens in practice: the operator creates copies of the SIM profile, synchronizing them through its network. When an incoming call is received, the signal goes to all connected devices, and the response from one of them terminates the connection to the rest.
*Note: The service is paid. The cost depends on the specific mobile operator.
Using eSIM to Share One Number Across Devices
eSIM is a built-in digital SIM card that allows you to download and activate a mobile number without a physical card. Such a SIM card works remotely via the Internet, and you do not need to visit the mobile operator’s office to activate it.
Some operators allow you to install the same eSIM profile on multiple devices β for example, a smartphone and a smartwatch β while maintaining a single number.

VoIP and Cloud-Based Number Sharing
In addition, to use a single number on multiple devices, you can choose VoIP services like Google Voice, which allows you to link a single virtual number to multiple devices. You can receive calls and send messages from the same account on different phones, tablets, or laptops β everything works via the Internet. This is especially convenient for travel, work, or backup communications. The main thing is a stable network connection and the availability of the application.
