AI chatbot useless and support unresponsive. Good way to waste some money ### 1/5 — Spam/Arnarques *2026-07-13, version 5.53.0* Numéro rempli de spam/arnarques ### 1/5 — No answer from customer support and technical issues with payment system *2026-05-20, version 5.51.0* I have been trying for 4 days to renew my Onoff number, but the payment system keeps failing. I tried different bank cards, browsers, clearing cookies, and both the app and website. Nothing works. I contacted customer support several times through tickets, forms, and emails, but received no response at all. Now my account is suspended because of a technical issue on their side. I urgently need this number for professional purposes, as recruiters use it to contact me. Very disappointing customer service and no support when it matters most. ### 1/5 — SERVICE CLIENT INEXISTANT ! *2026-05-19* J’étais l’une des premières à prendre un numéro sur cette application, je l’ai utilisé pendant des années, et puis un jour j’ai une proposition d’un abonnement bien plus avantageux, une offre spéciale limitée dont j’ai souscrit. Seulement à un moment donné, je me suis retrouvé avec deux offres, donc deux paiements, alors j’ai donc supprimé une des offres, mais malheureusement quelque chose a mal fonctionné et les deux offres se sont supprimés. J’ai mis du temps à m’en rendre compte, j’ai directement envoyé un e-mail au Service Client, j’ai reçu un message automatique m’assurant que mon message avait été reçu et que j’aurai une réponse aux 48 heures. Cela fait des semaines maintenant, et je n’ai toujours pas eu de réponse, je viens de voir que mon numero a été attribué à quelqu’un d’autre !! Gros problème, mon numero me sert pour beaucoup de comptes dont j’ai besoin de récupérer l’accès via des SMS, donc je suis coincée aujourd’hui et également c’était mon numéro professionnel donc je ne peux plus joindre aucun de mes clients, et j’ai également perdu tous les messages qui était lié à ce numéro dont des choses très importantes! Je viens ici en espoir d’obtenir cette fois de l’aide et de prévenir les nouveaux utilisateurs ! **Developer response:** Bonjour, Merci pour votre message et nous sommes sincèrement désolés pour la situation que vous décrivez. Nous comprenons parfaitement l’impact que cela peut avoir, notamment lorsque le numéro est utilisé à des fins professionnelles et pour l’accès à d’autres services via SMS. Lorsqu’un abonnement est supprimé ou arrive à expiration sans renouvellement, le numéro peut être remis en circulation après un certain délai, conformément à nos conditions de service. Une fois un numéro réattribué, il n’est malheureusement plus possible de le récupérer ni d’accéder aux anciens messages associés. Concernant votre demande au support, nous sommes désolés pour le délai de réponse anormalement long que vous avez rencontré. Nous comprenons votre frustration et prenons votre retour très au sérieux afin d’améliorer notre réactivité. N'hésitez pas à nous contacter à service-client@onoffapp.com si vous souhaitez être accompagné au mieux dans cette situation. Belle journée, L’équipe Care d'Onoff. ### 1/5 — Try google voice *2026-04-07, version 5.49.0* This app is not working getting messages that someone is trying to contact me but no call or message is getting in or out, feel like is a scam ### 1/5 — Not working *2026-04-07, version 5.49.0* The his app was working great until recently have so many issues and now my business is not getting connected with customers ### 1/5 — terrible, menteur *2026-03-27* Ils vous font payer avant même de vérifier votre identité. Je ne peux pas la vérifier car cela nécessite d'appeler un numéro français, et mon téléphone portable, comme la plupart des gens, ne permet pas d'appeler en France. J'ai demandé au service client s'il existait un autre moyen de vérifier mon identité, et ils m'ont répondu que non. Ce service est donc une arnaque. **Developer response:** Bonjour, Merci pour votre retour. Nous comprenons parfaitement la difficulté que représente cette étape depuis l’étranger. Cependant, la vérification d’identité par appel téléphonique est obligatoire pour des raisons légales et de sécurité . Il n’existe malheureusement pas de méthode alternative pour le moment pour valider l'identité que par appel. Si vous souhaitez annuler votre achat suite à ce blocage, je vous invite à revenir vers nous à l'adresse service-client@onoffapp.com, afin que nous puissions vous accompagner dans la démarche. L'équipe Care d'Onoff. ### 1/5 — Expérience extrêmement décevante *2026-03-26, version 5.48.0* J’ai tenté à plusieurs reprises d’ouvrir un compte en fournissant les documents demandés, mais aucun des fichiers envoyés n’a été reconnu par leur système, sans explication claire ni assistance efficace. Malgré cela, des frais m’ont été facturés, ce qui est totalement incompréhensible au vu de l’impossibilité d’accéder au service. Le manque de transparence, l’absence de réponse du support et cette facturation injustifiée donnent une très mauvaise image de cette société. Je déconseille fortement. ### 1/5 — Vérification 0/5 *2026-03-10, version 5.47.1* Tout allait bien en utilisant on off, que j’ai d’ailleurs recommandé à pas mal de personnes, cependant 1 an plus quand ça m’as demandé de vérifier à nouveau mon téléphone impossible de le faire , 0 retour du service client , bloqué pendant 20 jours sans pouvoir appel ni recevoir des appels , tout mon business est bloqué et aucun soutien ni aide de on off , une honte ### 1/5 — De la *2026-03-02, version 5.47.1* Rien à rajouter. Une horreur. ## Frequently asked questions about Onoff Numbers ### What does Onoff Numbers do?
