5sim and sms-activate vs NumZer0: price is not enough
5sim and sms-activate vs NumZer0 compared: prices from $0.008, 180+ countries, but no Mobile Money and pricey rentals. The alternative built for Cameroon.
TL;DR
- 5sim (5sim.net): leader since 2015, 1,100+ services, activations from $0.008, 150 to 180 countries. Cheapest per SMS, no subscription.
- sms-activate (sms-activate.io): 180+ countries, 20-minute activation + rental from 4 hours to 4 weeks. Cameroon rental from ~$10.14.
- Their shared blind spot: no Mobile Money, limited cards in Africa, English- or Russian-speaking support, pricey rentals for one-off use.
- NumZer0 does not play the cheapest-cent game: it makes checkout possible (MoMo, card, crypto), coverage verifiable (25 listed countries), and failure free (auto refunds).
5sim: unbeatable on price, unreachable on payment
Hard to argue with the numbers: 5sim advertises activations from $0.008, 1,100+ supported services, per-service success-rate stats, and a decent API. For a European user or an arbitrageur paying in crypto (22 coins accepted, 0.55% fee), it is the global cheap reference.
But read the help pages instead of the homepage: Visa/Mastercard are suspended outside South Africa and Nigeria, and there is no way to pay with MTN MoMo or Orange Money. In practice, a Cameroonian user without crypto must first buy crypto (fees plus an obstacle course) just to buy a $0.008 SMS. The headline price collapses once you count the cost of accessing payment.
sms-activate: the giant with a huge catalog and pricey rentals
sms-activate plays in the same league with 180+ countries and two modes: short activation (20 minutes, e.g. Telegram Russia ~$0.07, WhatsApp US ~$0.45) and rental (4 hours to 4 weeks). The catalog is gigantic and the aggressive affiliate program makes it a reselling tool too.
The flip side: a dense, intimidating UX for beginners, English/Russian-speaking support, and above all rentals that make no sense for the most common real use (a single verification). Renting a Cameroon number from ~$10.14 to receive one WhatsApp code has no economic logic next to a pay-per-use model. Add the absence of Mobile Money and you get an excellent service... for someone else.

| Cameroon covered | Likely, CM price unverified | Yes, rental from ~$10.14 | Yes, dedicated page | |
| Subscription | No | No (but 7-30 day rentals) | No, pay-as-you-go credits | |

The true-cost math
Never compare the SMS price alone. The true cost of a verification is:
SMS price + payment-access cost + (failure probability x lost SMS price) + time spent.
5sim wins the first term and loses the other three for a MoMo user: buying crypto to pay, no systematic refund documented, support unreachable in French. NumZer0 flips the equation: native payment, free failure, French-language journey. For 10 monthly verifications from Douala, the facially "pricier" option becomes the truly cheaper one.

Verdict
5sim and sms-activate remain the kings of international volume paid in crypto or international cards. But if you pay with Mobile Money, verify occasionally, and want to know before paying whether your country is covered: NumZer0 is built exactly for that case. The lowest price on the market is worthless if you cannot pay it.
