Using 2 numbers on 1 phone FAQs (Dual SIM)

Q: What is a Dual SIM device? What does "DSDS" mean?

A Dual SIM device has 2 (or more) SIMs. Device manufacturers determine how many and what type of SIM a mobile device can have (e.g., 2 SIM cards, or 2 eSIM's, or 1 SIM Card and 1 eSIM). Some new smartphones can store up to 8 eSIMs. Important: If you want a Dual SIM smartphone that can have 2 active plans/numbers at the same time, it must also be Dual SIM/Dual Standby (DSDS). Without DSDS, a mobile device may be equipped to store multiple eSIMs, but it can only have one of them activated with a carrier at a time.

Q: What can I do with a device that has multiple SIMs?

If your device has more than 1 SIM and is DSDS-capable, you can have multiple numbers on 1 phone (e.g., your business and personal numbers on the same phone). With DSDS, each SIM can be activated on a separate mobile phone number. Options include: Add a Second Number plan from Verizon, for just $15/mo. Have 2 numbers from 2 different carriers (domestic or foreign). Have 2 numbers from different Verizon accounts or with different Unlimited plans. Note: For laptops with Dual SIM, you can only use one SIM at a time. Important: You can only use data on one SIM at a time, for any device.

Q: How can I tell if my mobile phone is dual-number capable?

To have 2 usable, active mobile numbers, a smartphone must have: At least 2 SIMs: Each SIM is identified by an IMEI code. Dual SIM Dual Standby (DSDS) capability, enabled. Check the manufacturer's website to see if your smartphone is Dual SIM and DSDS-capable.

Q: How do I activate each SIM for my Dual-SIM device?

Find out how to activate a SIM card with Verizon. Important: If you're buying a Dual SIM device from Verizon, there's a 60-day SIM lock to prevent fraudulent activity. This means you must wait 60 days before activating another carrier's service on the second SIM. If you need to add a second carrier sooner, contact us.

Q: How does calling and messaging work when I have 2 numbers on 1 phone?

With a Dual SIM device that's DSDS-capable, you can make and receive calls and messages from either phone number. Only 1 line at a time can be selected for data. You decide which of your SIM is primary (the default) and secondary. The first number you had is the default, but you can change the assignments and the names of each SIM. Each time you place a call or start a text thread you can choose which number to use. If you get a call while you're on the phone, calls to that number go to Call Waiting. Calls to your alternate line go to that number's voicemail (you won't get a missed-call notice). Verizon's Call Filter app will work on one Verizon line of service at a time.
