TL;DR: If you are hunting for a Lusha alternative because your mobiles reach the wrong person, a new provider will rarely fix it. Every provider sells numbers that go stale once you export them. The fix is to check your numbers before you dial, whichever provider you keep, and to judge cost by price per number that reaches the right person.
Three pitches.
One of our callers dialled 110 numbers in a day and got to pitch 3 people. The rest were bad numbers, personal numbers, or people who would not engage. On another day it took more than 200 dials to get about 3 people on the phone. That is demoralising.
The bad numbers and the personal numbers hurt most. They kill the chance of a meeting before the rep gets a sentence out.
So you start looking for a Lusha alternative. You read a Kaspr vs Lusha review, then another. You run a trial. For two weeks the new data feels better. Then the same calls come back. "Wrong person." "This is my private phone." "He retired years ago."
We see this pattern on every list we touch. The answer sits after the export, in what happens to a number once it leaves the provider.
Is a Lusha alternative going to fix wrong-person mobiles?
Not on its own. A Lusha alternative swaps one database for another, and every database has the same weak spot. Mobile numbers belong to people. Private phones end up on business records. Numbers land on the wrong name. Carriers recycle old lines. People change jobs and keep their phone. Switching provider resets the clock for a few weeks. It does not stop it.
Answrd is part of Profitbl, which runs cold calling campaigns across Europe. Our teams have dialled lists from Kaspr, Lusha and others. The wrong-person calls show up on all of them. The share moves a little from list to list. It never goes away.
Why do bought mobiles reach the wrong person?
Bought mobiles reach the wrong person for four reasons, and none of them is a broken provider. Here is what we see on European lists, biggest problem first:
- The mobile is personal. This is the biggest problem in Europe right now. In our own campaigns, Kaspr, Lusha and our own enrichment have returned numbers from a different country than the person. A Luxembourg contact on a Belgian or French mobile is almost always a cross-border worker's private phone. We take those out before anyone dials. We once reached a head of department's wife on what we thought was his mobile.
- One number ends up on the wrong person. A shared phone, a typo in a signature, a merged record. We once dialled a spa while trying to reach an executive.
- The carrier recycled the number. The old owner dropped the line. The carrier gave it to someone new. Now a stranger answers a call meant for a CFO.
- The person left and kept the mobile. The number still reaches the right human, but he works somewhere else now. Some have left work altogether. We have called people who retired 10 or 15 years ago.
Every provider faces these four. They draw on similar inputs. Lusha's own help page says it "aggregates professional contact information from public sources." Public sources age at the same speed for everyone.
Shouldn't you just switch to the provider with the best accuracy claims?
You can, but the claim will not tell you what reaches your rep's headset. Accuracy figures are the vendor's own numbers, measured on the vendor's terms, at the vendor's chosen moment. The decay happens after you export. No accuracy figure covers the months your list sits in a CRM.
Look at how these figures travel. A Kaspr vs Lusha comparison on Appvizer states that "Kaspr achieves 97% verified data, Lusha 95%" (as of October 2026). The page gives no test behind either number. Both figures may hold on the vendor's own test. Your problem starts after that test ends.
Ask three questions of any accuracy claim:
- Verified against what? A number can be "verified" because it exists on a network. That says nothing about who answers it.
- Verified when? A figure from the day of the check says little about the day your rep dials.
- Verified for which country? A strong US figure tells you little about a Belgian mobile.
What is the right way to compare Kaspr vs Lusha on price?
Compare price per number that reaches the right person, and ignore price per number. A cheap number that reaches a stranger costs you a credit, a rep's time, and a bad first touch. The real unit is a right-person conversation. Price everything against that.
Here is an illustrative example. We made up the figures to show the maths. They are not our data and not any provider's data.
- Provider A: €0.50 per mobile. Say 60 out of 100 reach the right person. That is €50 for 60 right numbers, or €0.83 per right number.
- Provider B: €0.35 per mobile. Say 40 out of 100 reach the right person. That is €35 for 40 right numbers, or €0.88 per right number.
Provider B looks 30% cheaper on the price page. Per right number, it costs more. And we have not yet counted the rep's time on the 60 wasted dials.
Now add the rep. Say each wrong dial eats two minutes, between the ring, the confused stranger and the CRM note. On Provider B, 60 wrong dials cost two hours of selling time per 100 numbers. That cost never shows up on a pricing page.
If you want to run this on your own list, the pickup rate calculator shows what your current numbers cost per conversation.
Is calling the wrong person on a mobile a GDPR problem?
Yes, it can be. A mobile number linked to a name is personal data. If the link is wrong, you hold inaccurate personal data about two people: the one you meant to reach and the one who answered. The GDPR accuracy principle asks you to fix that.
The UK regulator puts it plainly. The ICO's guide to the accuracy principle says personal data must be "accurate and, where necessary, kept up to date." It adds that you "must take reasonable steps to correct or erase" data you find is wrong. The same principle sits in Article 5 of the EU GDPR.
We hear what that means on the phone. Several people we reached on the wrong number were angry about GDPR, most of all in France and Switzerland. They ask where you got their number. Your data provider sold it to you. You made the call. The risk lands on you.
Cross-border personal mobiles make this worse. A French private number on a Luxembourg prospect's record puts someone's home phone, in another country, on your call list. Checking a number before you dial is the reasonable step, and it protects your pickup rate too.
How do you stop dialling the wrong person, whichever provider you keep?
Check your numbers before you dial them. Keep the provider you trust. Pull your mobiles from Kaspr, Lusha or FullEnrich as usual. Then check them before they reach the dialler, so your reps only call numbers that pick up and reach the person you meant.
Here is the routine we run on our own campaigns:
- Export from your provider as usual. Keep your current stack.
- Check every mobile before the first dial. Flag wrong, dead and wrong-person numbers.
- Dial only what passes. Your reps stop burning the morning on strangers.
- Check again before you retarget. A list you checked in March has aged by September.
That is what Answrd does. You upload the numbers you already have. You get back numbers that pick up, with the wrong and dead ones flagged. You pay €0.75 per verified number, with credits that never expire. We do not sell data. If you need a source, we will point you to providers like Kaspr, Lusha or FullEnrich, and you pick.
The results on our own campaigns:
- Engineering services campaign: real pickup was 6% before verified numbers and 17% after.
- Security software campaign: 12.8% real pickup, against a history of between 2% and 5%.
- One recent list: of 131 numbers checked, 13 were bad. Of the good ones, most reached the right person and the rest reached a named voicemail.
A tool that only checks if a line is live will miss the private and job-change cases. We cover why in our post on the limits of HLR lookups. And if your pickup still drags after the numbers are clean, look at the dialler. Our power dialer vs parallel dialer post shows why parallel dialling halved our pickup.
Frequently Asked Questions
What is better than Lusha?
For mobile numbers, no provider beats Lusha on every list in every country. They all decay after export. The bigger gain comes from checking whichever numbers you buy before you dial them. That is the step that raises pickup.
Is Lusha trustworthy?
Lusha is a B2B data provider with public help and privacy pages. Those pages say it collects professional contact data from public sources. Like every provider, its numbers age once you export them. Check them before you dial, the same as you would with any other source.
How did Lusha get my details?
Lusha's help centre says it "aggregates professional contact information from public sources." Under GDPR you can also ask any provider what data it holds on you and where it came from.
Kaspr vs Lusha: which one has more accurate mobiles?
Both publish accuracy claims, and third-party reviews repeat figures like 97% for Kaspr and 95% for Lusha. Those are the vendors' own terms, measured before export. On a live European list, the gap between the two matters less than how old your list is. Test both on the same 100 contacts and count right-person pickups.
Are there good Cognism alternatives for European mobiles?
Teams selling in Europe often look at Kaspr, Lusha and FullEnrich. Whichever you pick, the same four problems apply: private mobiles, wrong links, recycled numbers and job changes. Pick on price per right number, and check numbers before you call.
Why do my Lusha numbers go to the wrong person?
Most often the number is a private mobile, sometimes from another country. Other times it sits on the wrong name, the carrier recycled it, or the person left and kept the phone. The number aged after export, which happens with every provider.
Is it legal to cold call a mobile number from Lusha or Kaspr in Europe?
Rules differ by country, so check the local rules before you call. GDPR also asks you to keep personal data accurate. Calling the wrong person on a private number is the clearest way to break both. Check numbers first and log where each one came from.
Keep your provider. Check the numbers.
A Lusha alternative will not fix wrong-person mobiles on its own. Every provider's numbers go stale after export. Keep the source you like, check every mobile before the first dial, and measure cost per right-person number.
Start with your own list. Test 100 numbers free and see how many of your current mobiles reach the right person. If you would rather talk it through, book a 15-minute call.
