Can Two Phones Have the Same Number?
Not as two full smartphones. Your number can ring a smartwatch, tablet, or computer, and calls can forward to a second phone. Here is what works and how.
Quick answer
Not as two full smartphones, each with its own SIM. A carrier number is active on one phone's SIM or eSIM at a time. You can still share your number with a smartwatch through your carrier, answer calls on a tablet or computer, or forward calls to a second phone.
Your phone number belongs to one SIM or eSIM on your carrier's network. When you activate the number on a new phone, the old SIM stops working. That is why there is no setting that puts the same number on two smartphones at once.
Copying a SIM to make a second one is not an option either. The FCC describes phone cloning as a form of cell phone fraud.
What you can do depends on the second device and on what you need it for.
Share your number with a smartwatch
This is the closest thing to one number on two devices, and carriers sell it for watches.
An Apple Watch with cellular uses your iPhone's number. In Apple's words, "your iPhone and Apple Watch share the same number," and the watch must use the same carrier as the iPhone.
Carriers offer the same idea for other watches:
- Verizon Number Share lets a smartphone share its number with smartwatches and a few other connected devices, up to five per phone. Verizon's FAQ lists a $15 monthly line access charge for each wearable and says tablets are not eligible.
- AT&T NumberSync syncs your smartphone number to compatible devices such as an Apple Watch with cellular, an iPad, a Mac, and some smartwatches, so you can make and receive calls on them.
- T-Mobile has changed its same-number watch plans over time. Check the current options with T-Mobile before you buy a cellular watch.
- In Canada, Bell's NumberShare lets "a connected device and smartphone share the same phone number." Rogers and Telus sell shared-number smartwatch plans under their own names.
Each watch usually needs its own plan on your account, even though it uses your number.
Answer calls on a tablet or computer
You do not need a second phone plan to pick up calls on another device you own.
iPhone: With Calls on Other Devices, your iPad or Mac can make and receive calls using your iPhone's number. The devices must use the same Apple Account and the same Wi-Fi network as the iPhone, unless your carrier supports Wi-Fi Calling on other devices. Text Message Forwarding does the same for SMS on your Mac or iPad.
Android: Samsung's Call & text on other devices works between a Galaxy phone and a Galaxy tablet, watch, or PC on the same Samsung account. On Windows, Microsoft's Phone Link can make and receive calls from your Android phone on your PC over Bluetooth.
Google Fi: With an Android phone on Fi, you can also call and text from the web. Google says this feature is not available for iPhone and iPad users.
These features extend your phone. They do not replace it, and most of them need the phone to stay on and connected.
Forward calls to a second phone
If you carry two phones and want calls to your main number to reach the other one, use call forwarding. Verizon, for example, lets you forward mobile calls to another number, including another mobile phone, with no monthly fee on most plans.
Forwarding works one way. Calls and texts you send from the second phone still show that phone's own number.
Ring several phones from one app number
Google Voice can ring your linked phones when someone calls your Voice number. That number is separate from your carrier number, so this is a different way to give several devices one number people can reach.
What to check first
- Carrier and plan: Number sharing is a carrier feature. Check that your plan supports it and what each connected device costs.
- Device: Watches usually need to match your phone, for example an Apple Watch with an iPhone or a Galaxy Watch with a Samsung phone.
- Account: Calling on other devices needs the same Apple, Samsung, or Microsoft account on each device.
- Moving, not sharing: If you are switching phones, transfer the number instead. On iPhone, eSIM Quick Transfer moves it to a nearby new iPhone and deactivates the old SIM.
Need the opposite: two numbers on one phone?
If what you need is separate numbers rather than one number everywhere, a single phone can hold two numbers through Dual SIM, eSIM, or a second-number app. See how two phone numbers work on one phone and how to add a second number on iPhone.
Want a separate number instead?HashPhone adds a second US or Canadian number for calls and texts to the phone you already carry.
