iPlum vs Line2: Which Business Phone App Is Actually Worth It?
This isn't a close call. One product has 199 G2 reviews and a 4.3 rating. The other has 14 reviews, a 2.7 rating, and zero recent G2 activity. With 41.6M business VoIP lines now active in the US, there's no shortage of second-line apps - but the iPlum vs Line2 matchup is lopsided. We've compared dozens of these tools, and this is one of the most one-sided we've seen.
30-Second Verdict
iPlum is the better business phone app for almost everyone. It's cheaper on annual billing ($8.99/mo vs $13.75/mo), has dramatically better user reviews, and it's the only option here that clearly includes HIPAA compliance with a signed BAA on its Professional plan. Line2 is only defensible if you're already locked in and have zero compliance needs.
Pricing Compared
iPlum's pricing page is straightforward. Line2's is confusing - their pricing page header advertises $9.99/month ($7.99 annually), but the actual Starter plan is listed at $15.99/month ($13.75 annually). That's a real discrepancy, and it doesn't inspire confidence.
| iPlum Standard | iPlum Professional | Line2 Starter | Line2 Business | |
|---|---|---|---|---|
| Monthly | $13.99 | $20.99 | $15.99 | $25.99 |
| Annual (per mo) | $8.99 | $14.99 | $13.75 | $21.83 |
| HIPAA/BAA | ❌ | ✅ | ❌ | ❌ |
| Call Recording | ❌ | ❌ | ❌ | ✅ |
| Auto-Attendant | ✅ | ✅ | ❌ | ✅ |
iPlum also offers an Enterprise tier at $25.99/user/month on annual billing (or $30.99 monthly) with call recording and 10-year archiving. Toll-free numbers run +$5/month, and carriers now require TCR texting registration - that's a one-time $20 fee per business.
Line2 advertises "unlimited" calls and texts for US/Canada, but its unlimited plans are subject to overages per its Terms of Service. Read the fine print. They do offer a 30-day money-back guarantee, which partially offsets the pricing confusion.
HIPAA and Compliance
If you're in healthcare, legal, or financial services, this comparison is basically over before it starts.
iPlum Professional ($14.99/user/month on annual billing) includes a signed Business Associate Agreement and secure encrypted texting. Line2's marketing pages don't position the product around HIPAA, don't mention a BAA, and don't reference encrypted messaging. For regulated industries, there's nothing to debate here.
Picking a phone app takes 20 minutes. Building a list of verified decision-makers to actually call? That's the real bottleneck. Prospeo gives you 125M+ verified mobile numbers with a 30% pickup rate - and 143M+ emails at 98% accuracy. Data refreshes every 7 days, not 6 weeks.

What Real Users Say
Line2's Decline
Line2 carries a 2.7/5 on Trustpilot from 760 reviews. The pattern is consistent: messages don't arrive unless you sign out and sign back in, the app freezes or disconnects mid-call, and customer service takes forever to respond. Capterra tells a similar story - 3.6/5 overall, with ease of use at 4.0 but customer service dragging at 3.2/5. Multiple reviewers describe porting out as a nightmare, with port requests that weren't received or got rejected over weeks of back-and-forth.
Zero recent reviews on G2 is a stagnation signal that should make any buyer cautious.
iPlum Holds Up
iPlum sits at 4.1/5 on Trustpilot from 225 reviews and 4.3/5 on G2 with 40 recent reviews.
The G2 sub-ratings tell the story: iPlum scores 9.2 for "Meets Requirements" vs Line2's 6.7, 8.4 for support quality vs Line2's 6.3, and 8.6 for product direction vs Line2's 3.5. It's not perfect - a Reddit thread from therapists flags texts not sending and a frustrating bug where deleting and reinstalling the app wipes your entire text history. But the complaint volume is a fraction of what Line2 generates.
Who Should Pick Which
Use iPlum Professional if you're in a regulated industry. HIPAA compliance plus a signed BAA at $14.99/user/month annually is genuinely hard to beat at that price point.
Use iPlum Standard if you just need a reliable second line. At $8.99/user/month annually, it's cheaper than Line2's Starter and has better reviews across every platform that matters.
Stay on Line2 only if you're already using it, it works for your specific setup, and you have zero compliance needs. But know the risks - porting out later may be painful, and the app's reliability track record isn't reassuring.
Here's the thing: if your average deal size is under a few thousand dollars and you're a solo operator, even iPlum might be overkill. Google Voice is free and handles basic second-line needs. But the moment you need compliance, call trees, or professional texting, iPlum is where you land.
When the Problem Is Finding Who to Call
A business phone app gives you a number. It doesn't tell you who to dial. If you're in B2B sales or outbound, the harder problem is building a list of verified contacts worth calling - and we've watched teams spend hours on that bottleneck after spending 20 minutes picking a phone app.
Prospeo handles that side of the equation with 300M+ professional profiles, 98% email accuracy, and 125M+ verified mobile numbers. There's a free tier, no contracts, and data refreshes every seven days. Once you've picked your phone app, it's the logical next step.
You just saved $5-$13/month picking iPlum over Line2. Now invest that clarity in the contacts you're calling. Prospeo's 300M+ profiles cost roughly $0.01 per verified email - 90% cheaper than ZoomInfo - with no contracts and a free tier to start.
A second line without a pipeline is just a number ringing into nothing.
FAQ
Can I port my number from Line2 to iPlum?
Yes, both support number porting. Line2 users consistently report porting-out friction - lost requests, rejected transfers, and weeks of back-and-forth. Budget extra time and note that iPlum charges a $19.99 port-out fee.
Is Line2 HIPAA compliant?
Line2 isn't positioned as HIPAA-compliant on its official marketing pages, and those pages don't mention offering a BAA. iPlum Professional at $14.99/user/month annually includes a signed BAA and encrypted texting - the minimum viable option for healthcare, legal, or financial communications.
What if I need verified contact data, not just a phone line?
A second-line app gives you a number, not a pipeline. If your bottleneck is finding decision-makers rather than reaching them, a B2B data platform like Prospeo - with 143M+ verified emails and 125M+ direct dials - will move the needle more than any phone app upgrade. The free tier includes 75 email credits per month.
