Claro is a scam

I paid for claro flex and got stuck in the esim installation process, then that was the last of it, my account was erased from their system, contacted customer report, they said they issued a refund, which never came, similar things happened in their offline store another time, their business model is built upon deceiving and scamming.

App não atualiza as informações

Esse app está muito ruim, troquei meu plano por um plano superior por orientação de um próprio atendente para tentar resolver um problema já que estou no Exterior, e o app não atualiza, não consigo migrar meu chip para um Esim, mesmo estando com um celular que suporta apenas Esim, não tem entrada pra chip, ou seja, estou pagando por um serviço que não estou usando. Se não conseguirem resolver meu problema vou ter que entrar com uma reclamação.

Olá, PsWilliamLeite! Estou aqui para te auxiliar. Por favor, acesse o link abaixo e compartilhe os detalhes sobre o ocorrido. Dessa maneira, posso verificar o que houve e te oferecer todo suporte necessário nessa questão: https://www.claro.com.br/chatflex Fico à sua espera! Estamos à disposição sempre que precisar. :)

Consegui colocar cartão, mas erro na descrição de vocês…

Realmente após digitar todos os dados como vocês descrevem, não prosseguia. O erro de vocês, está no campo, digitar seu nome como aparece no cartão. No meu cartão está com uma quantidade de carácteres que vocês erraram na programação e não aceita somente o número que o meu cartão possui. Então eu coloquei meu nome completo, que Não é como aparece no meu cartão de crédito. Ou vocês erraram na programação de quantidade de carácteres mínimos, ou na descrição desse campo, tem de ser para digitar seu nome completo. Ainda vai ficar 1 estrela.

Olá! Lamentamos pela sua experiência. É importante que seu aplicativo esteja atualizado na última versão! Faça a limpeza de cache, reinicie o app, caso esteja preenchendo os campos colando os dados do cartão, é necessário apagar um dígito e depois digitar manualmente, de todos os campos que colou, após essa ação o botão é habilitado, faça um novo teste. Se persistir, nos contate através do link: https://www.claro.com.br/chatflex que iremos te ajudar.

THEY CANCELED THIS PROGRAM

As of January 14, 2026, they no longer issue these flex passes. But they didn’t remove the app from the store. App will let you register and even pay before you find out that it doesn’t work.

International users eSIM suspended!

Ok I get it the flex plan is not offered anymore but why not telling this right away.
Spent 45 minutes had to chat with support to get this:
“. ..that's because Claro Flex Pass sales are temporarily suspended, as for now we still don't have a date to resume the service”
