Zadarma Review 2026: Pricing, Pros, Cons & What Users Actually Think
$0/month for a cloud PBX sounds like a dream - until you're uploading a selfie holding your passport just to activate SMS. We set up Zadarma's free tier and had a working PBX in under an hour, but SMS activation took three days and two rounds of document uploads. Here's the full breakdown so you can decide before you commit.
30-Second Verdict
Zadarma's ratings tell a split story: 4.4/5 on G2 (21 reviews), 3.7/5 on Capterra (62 reviews), and 3.3/5 on Trustpilot (651 reviews). People who survive setup love the value. People who hit verification walls leave angry.
Best for: budget solopreneurs and micro-teams needing international numbers in 110+ countries. Skip Zadarma if you need reliable SMS, responsive support, or a system running by Friday.
Zadarma Pricing Breakdown
Zadarma runs three PBX plan tiers: Standard, Office, and Corporation. Pricing varies by region - G2 shows Office at $39/month in the US/Canada and $22/month in Europe, so check the rates for your location before signing up.
If you're comparing options, it can also help to scan a few Dialpad alternatives and MightyCall alternatives to sanity-check total cost and setup time.
| Standard | Office | Corporation | |
|---|---|---|---|
| Price (US/Canada) | $0/mo | $39/mo | $79/mo |
| Users | 5 | 10 | 20 |
| Virtual numbers | 0 | 4 | 8 |
| Included minutes | 0 | 500 | 1,000 |
| Toll-free numbers | 0 | 1 | 2 |
| Toll-free minutes | 0 | 200 | 600 |
| AI agent minutes | 0 | 100 | 200 |
| Speech recognition minutes | 0 | 400 | 1,000 |
| Recording storage | 200MB | 2GB | 5GB |
| Concurrent calls | 4 | 4 | 8 |
Additional PBX/CRM users and phone numbers run $2/month each. Per-second billing applies across all tiers, and incoming calls on virtual numbers are free (except toll-free).
The EU CallerID Trap
On the Standard calling plan, you get 100 free minutes/month to five destinations - US, Canada, Poland landlines, Spain landlines, Germany landlines - but only with a monthly top-up, and minutes expire after 30 days. After that, rates are reasonable: $0.012/min to the US, $0.006/min to Canada.
Here's the thing most people miss. Those cheap European rates only apply when you're calling from an EU number set as your CallerID. Without it, Spain jumps from $0.015/min to $0.48/min and Germany from $0.01/min to $0.39/min - a 32x difference for Spain. Check Zadarma's rate page before assuming you're getting the headline rate.
Virtual Numbers and SMS
US and UK numbers run $4/mo or about $2/mo paid yearly. Germany is $6/mo ($3/mo yearly). Numbers are available in 110+ countries.
Want SMS? You'll need to prepay the number for three months and pass identity verification with a passport or ID upload. Most users don't discover this until after purchase - and it's the source of a huge chunk of negative reviews. (If SMS is core to your outbound motion, read up on cold texting before you commit to any provider.)
Zadarma gives you cheap calls - but cheap calls to wrong numbers still waste rep time. Prospeo's 125M+ verified mobile numbers deliver a 30% pickup rate at ~$0.01/lead, so every dial your team makes actually connects to a real decision-maker.
Stop burning call blocks on dead numbers. Start dialing verified mobiles.

- AI voice agent included on paid plans, supporting 8 languages at no extra cost
What Users Hate
Verification Friction
This is the #1 complaint across every review platform. Zadarma requires your passport, a utility bill, and a selfie holding your ID - sometimes across multiple rounds. The requirements stem from legitimate regulatory compliance for virtual numbers, but the process is poorly communicated, rejections feel arbitrary, and setup can stall for days. In our experience, what should've been a 30-minute setup stretched to three days. Software Advice reviewers call it "ridiculous." Zadarma has publicly responded on review platforms, attributing the requirements to local telecom regulations.
Support Quality
Zadarma advertises 24/7 support, but it's ticket-only, and users report multi-day response times. Capterra's customer service sub-score sits at 3.2/5 - the lowest of any category. We tested it ourselves: support replied within 48 hours but with a generic template. If something breaks on a Friday, don't expect a real fix before Tuesday.
SMS Unreliability
Between the 3-month prepay requirement, mandatory identity verification, and reports on r/VOIP of users who can send but not receive SMS, this isn't a platform for SMS-dependent workflows. Full stop.
Call Reliability Concerns
Trustpilot reviews mention calls cutting out after roughly 5 minutes. A Reddit user reported calls stopped completing entirely - Zadarma support said outgoing calls require a Zadarma-connected number as CallerID, a requirement that wasn't clear at signup. That kind of gotcha erodes trust fast.
Who Should Use Zadarma
Zadarma is a technical VoIP platform sold to non-technical buyers. Most complaints stem from that mismatch, not from the product being broken. If you're a budget-conscious solopreneur or small remote team under 10 people who needs international numbers and can tolerate bumpy onboarding, the value-to-cost ratio is hard to beat once you're through verification.
Skip Zadarma if you need SMS reliability, same-day support, or a system that works out of the box. Dialpad and OpenPhone cost more but offer cleaner UX and faster setup.
Let's be honest about something most VoIP reviews won't tell you: a cheap dialer paired with bad contact data is still expensive in wasted rep time. Once your phone system is live, data quality becomes the real bottleneck. We've seen teams pair a budget phone system with Prospeo's 125M+ verified mobile numbers and hit a 30% pickup rate at roughly $0.01/lead - that combination keeps cost-per-conversation genuinely low. If you're building a repeatable outbound motion, a documented cold calling system and a reliable sales prospecting database matter more than shaving $10 off your VoIP bill.
You just spent days fighting Zadarma's verification process. Don't pair that effort with unverified contact lists. Prospeo refreshes 300M+ profiles every 7 days and verifies every mobile through a 5-step process - so your reps spend time talking, not leaving voicemails at disconnected numbers.
Your phone system is live. Now give it numbers worth dialing.
FAQ
Is Zadarma legit?
Yes. Zadarma has been operating for over 18 years, with virtual numbers in 110+ countries and millions of clients. The verification complaints reflect regulatory compliance requirements, not a scam - though the process is poorly communicated and frustrating.
Does Zadarma SMS actually work?
Only after you prepay your number for three months and complete identity verification with a passport or ID upload. Multiple users report being able to send but not receive. If you need SMS on day one, look elsewhere.
How does Zadarma compare to Dialpad or OpenPhone?
Zadarma is dramatically cheaper - $0-79/mo for a team versus $15-27/user/mo for Dialpad or $15-23/user/mo for OpenPhone. You trade money for time and convenience: Dialpad and OpenPhone offer polished UX, faster setup, and better integrations at a premium. For teams that just need a working phone system without a learning curve, the extra spend is worth it.
What's the best way to get accurate phone numbers for cold calling?
Your dialer handles the calling, but your connect rate depends entirely on data quality. Pairing a budget VoIP system with a verified contact database keeps your cost-per-conversation low without sacrificing pickup rates.
