Second Phone Number for Business: Options Compared

The main ways to get a second phone number for business are a second line on your existing phone (eSIM or dual SIM), a separate business phone, a calling app, or a cloud business phone system. For one person who only needs to make and take calls, a second line is simplest. As soon as anyone else needs to answer, text from the same number, or you want after-hours routing, a cloud phone system is the better fit.

This guide compares the options on what matters day to day: who can answer, where texts live, what happens after hours, and how costs grow as you add people.

What you need a second number to do

Answer these before comparing products:

1. Will anyone besides you ever answer it?
2. Will you text customers from it?
3. Do you want calls to stop ringing outside business hours?
4. Do you need call recording, voicemail transcription or analytics?
5. Will you list it publicly, on Google, your website or a vehicle?
6. Might you sell the business or hand the number to a partner?

If every answer is no, a second SIM line is fine. Each yes pushes you toward a system the business owns.

Option 1: Second line on your phone (eSIM or dual SIM)

Many current phones hold two plans. Apple documents Dual SIM with an eSIM for iPhone XS and later, and lists separate business and personal numbers as a typical use.

Pros: cheap, simple, works on the cellular network without data.

Cons: only your phone rings; texts and call history stay on one device; no shared inbox, ring groups or business hours routing.

Option 2: A second phone

A separate handset and plan for the business.

Pros: clear separation; you can leave it behind on weekends.

Cons: two devices to carry, and still only one person can answer.

Option 3: Calling and texting app

Apps that give you a second number over data. Features vary widely: some are personal-use products, others are business tools with team features.

Pros: no new hardware; often quick to set up.

Cons: depends on data or Wi-Fi; business features and texting registration support vary; check who owns the number if you cancel.

Option 4: Cloud business phone system

The number lives in a hosted system. Calls ring browsers, desk phones or cell phones; texts go into a shared inbox; routing follows your hours.

Pros: teammates can answer; history stays with the business; business hours, voicemail transcription, recording and analytics are usually included or available.

Cons: monthly cost; app or browser side needs a data connection.

How costs grow with team size

Most business phone systems charge per user. Using each vendor's published list price for its lowest plan that includes calling and texting, billed monthly and checked on September 28, 2026:

Vendor and plan	Per user	5 users
Quo Starter	$19	$95
Ooma Office Pro	$24.95	$124.75
RingCentral RingEX Core	$30	$150

Prices exclude taxes and fees, Ooma charges a one-time activation fee, and annual contracts lower some prices. Check each vendor's pricing page before deciding, because these change.

Per-user pricing is reasonable for one person and adds up as you add part-timers and seasonal staff. Our guide on budgeting for a phone system walks through the full cost, including fees that do not show on pricing pages, and hidden fees on business phone bills lists what to check.

Texting from the second number

If you plan to text customers from a local number, US carriers require businesses to register their brand and campaign through the 10DLC system administered by The Campaign Registry. Unregistered business texts are often filtered. Ask any provider:

• Do you handle the registration?
• What is the fee, and is it one-time or monthly?
• How long does approval usually take?

Then get consent before you text. See how to get consent to text customers.

Local, toll-free or keep your old number

• Local numbers suit businesses serving a region; customers recognize the area code. See how to choose an area code.
• Toll-free suits national sales and support. See local vs toll-free numbers.
• Existing number: if customers already know a number, port it rather than starting fresh. See how to port a business phone number.

Decision checklist

• I know who will answer the number now and in a year
• I know whether I will text from it, and how registration works
• I have priced the option for my current and next-year team size
• The business, not an individual, will own the number
• I can port the number out if I switch
• After-hours calls will go somewhere other than my pocket

For the reasons to separate lines in the first place, read why to separate business and personal numbers, and for running the line on the phone you already carry, see using a business number on your personal cell.

Mistakes to avoid

• Picking the cheapest option for today's team and paying to switch in six months.
• Letting an employee's personal app account own the number your customers call.
• Choosing a provider that makes porting out hard, so you're stuck if service slips.
• Printing the new number everywhere before testing greetings, routing and texting.

Where Callata fits

Callata is a cloud business phone system priced at $99 a month with five users included and $20 a month for each additional user. The plan includes up to three local numbers, unlimited inbound calling, 1,500 pooled outbound US and Canada minutes per user each month (then $0.01 a minute), a browser softphone and cell ringing that shows your business number, a shared texting inbox after carrier registration (a one-time $49 fee), voicemail transcription, call recording with AI summaries, business hours routing and E911 on every number.

If you need a second number today and expect to add people later, start with Callata; the base price stays the same until you pass five users. At five users that is $99 a month, compared with $95 to $150 for the plans in the table above.
