Why "Instant Setup" actually matters.

In 2026, buying a business phone number shouldn't be harder than ordering a pizza. Yet, traditional carriers still force you to visit a store, sign a contract, or wait 3-5 business days for a physical SIM card to arrive in the mail.

At +OneCallix, we built our infrastructure on VoIP (Voice over IP) technology. This allows us to bypass the physical limitations of SIM cards completely.

The Speed Gap: Us vs. Them

We ran a test. We tried to set up a new business line with a major US carrier (Verizon/AT&T), a "Second Line" app, and +OneCallix. Here is the time-to-first-call data:

Why we are cheaper (The Math)

Most second-line apps charge between $10 and $25 per month. Why? Because they are reselling expensive outdated infrastructure.

We built our own stack. By stripping away "enterprise bloat" (features freelancers don't need, like faxing or conference bridges), we pass the savings directly to you.

Feature Comparison Breakdown

Here is the raw data on features relevant to freelancers and gig workers.

Feature	Carrier Add-on	Sideline/Burner	+OneCallix
Monthly Cost	$15.00	$9.99	$2.00
Privacy Protection	Low	Medium	High
Desktop Calling	No	Rarely	Yes
Contract Required	Yes (12mo)	No	Never

The Verdict

If you need a complex phone system with desk phones and fax machines, go with a traditional provider. But if you are a freelancer who just wants to separate work from life and look professional instantly, +OneCallix is mathematically the best choice.
