MethodHow we scored these tools▾
Prices are from each vendor's pricing page on October 6, 2026. Apollo phone credit rules follow our Apollo phone numbers post. Per-mobile dollars are our math from printed credit prices.
Who for
buy if
- You need B2B mobiles or direct dials and want a price per found number.
- You already pay for Apollo and need a fill tool for phone misses.
- You want pay-on-find enrichment instead of a big annual data contract.
- You are done with consumer reverse-lookup search results.
skip if
- Skip this if you want enterprise file append (Melissa / Experian class). That is a different buyer.
- Skip this if you only need Clay table logic. Clay is a spreadsheet enrichment product, covered elsewhere.

Cost per found mobile is the unit
FullEnrich's pricing page (and pricing.md) prints mobile = 10 credits and $0.055 per credit at 1,000 credits a month ($55). That is about $0.55 per found mobile. Failed lookups cost 0.
Search results rarely show that math. They sell categories. Budget the find.
Coverage beats a cheap reveal · with a vendor label
Derrick, a phone-finder vendor, published a test on 100 hard enterprise profiles. FullEnrich returned 87%. Apollo returned 42%. Derrick's own product returned 91%. ProntoHQ returned 93%.
FullEnrich did not win that test. The useful contrast is FullEnrich vs Apollo on the same hard list, with the vendor bias stated. Cheap per-reveal pricing is a different thing from cheap per found number on hard accounts.
Apollo is a seat you may already own
Apollo bills phones when a reveal finds a number. Our Apollo phone numbers post uses 8 credits per found mobile. Office and HQ numbers can be free with an email request.
Keep Apollo for the seat you already pay for. Keep FullEnrich as the mobile fill when the list is hard or the Apollo find rate drops.
BetterContact listed-price math
BetterContact Starter is $15 for 200 credits. Pro is $49 for 1,000 credits. A mobile is 10 credits, so about $0.75 and $0.49 when valid.
A competitor post on October 2, 2026 worked those same public listed prices into per-mobile dollars. Use that writer's math. FullEnrich still comes first for mobiles.
Phone append and reverse lookup are different buyers
"Phone append" search results lean Melissa, Experian, and Accurate Append. That is enterprise file append.
"Email to phone" and reverse lookup results lean consumer tools. This guide covers GTM waterfall finders for B2B mobiles. Shop those other lanes only when that job is the one you have.
