oneSMS vs NumZer0: which virtual number for your OTPs?
oneSMS vs NumZer0 compared: per-SMS pricing, country coverage, Mobile Money payment, French support. Which one for WhatsApp and Telegram verification?
TL;DR
- oneSMS (1-sms.com) is a per-SMS OTP platform: around $0.10 for Telegram Global, $0.18 for ChatGPT, no subscription shown.
- Its weak spot for Central Africa: publicly undocumented payment methods, English-only interface and support, unconfirmed Cameroon coverage.
- NumZer0 answers all three: MTN MoMo and Orange Money payment, French support, Cameroon plus 24 countries listed in black and white.
- If you pay by international card and target US/EU services, oneSMS remains an option. If you pay with Mobile Money from Cameroon, NumZer0 is the rational choice.
What oneSMS offers
oneSMS, operated via 1-sms.com, is an online OTP reception platform with a bulk-sending API. The model is simple: you pay per received SMS, with no subscription. Observed entry prices are aggressive: Telegram Global around $0.10, TikTok around $0.16, ChatGPT US/EU around $0.18. For a developer automating bulk verifications with an international card, it reads well.
Where it gets complicated is everything around the price: the exact list of covered countries is not published, accepted payment methods are not publicly documented, and everything (interface, support) is English-only. For a user in Douala or Yaounde, these three blind spots are deal-breakers: no way to know before paying whether the target service works, or how to top up without an international card.
What NumZer0 offers
NumZer0 sells temporary virtual numbers for SMS verification on a credit model: you top up a pack, each verification spends credits, and any SMS not received within 20 minutes triggers a full automatic refund. No subscription, no forced rental.
Three structural differences with oneSMS:
- Local payment first. Top up with MTN Mobile Money, Orange Money, bank card, or crypto. This changes everything in Cameroon: no international Visa needed.
- Displayed coverage. 25 countries listed publicly, including Cameroon, Ivory Coast, Nigeria, and Senegal, each with its own page (see all covered countries).
- French-language journey. Interface, support, and docs in French and English, with the automatic refund guarantee written on the product pages, not buried in an unfindable FAQ.

Who is each service for?
Pick oneSMS if you are English-speaking, equipped with an international payment method, and your verifications target US/EU services in bulk via API. The headline price is unbeatable there.
Pick NumZer0 if you are in Cameroon or francophone Africa, you pay with Mobile Money, you want verifiable country coverage before buying, and support that answers in French. The true cost of a verification also includes time lost when the SMS never arrives: automatic refunds change the math.

Verdict
oneSMS wins on headline per-SMS price for high international volumes paid by card. NumZer0 wins on everything that makes a verification actually possible from Cameroon: paying with MoMo, knowing which countries are covered, getting refunded automatically on failure. For individual or low-volume use in francophone Africa, it is not close.
