Mais Voz is a Brazil-based mobile communications brand. Its website states that it is a brand under DRY COMPANY DO BRASIL TECNOLOGIA LTDA and that it holds the relevant qualifications under Anatel Resolution 550/2010, with mobile phone services provided by Surf. Its focus is on “real 5G,” physical SIM/eSIM, number portability, top-ups, and recurring plans. Overall, it is positioned more like a consumer-facing MVNO mobile operator than an email marketing, bulk SMS, or developer communications API platform.
In terms of channels, Mais Voz covers voice calls, SMS activation/number-porting confirmation, WhatsApp customer support, and billing notifications. It also notes that eSIMs can be sent via WhatsApp or email. Its plan highlights include unlimited WhatsApp usage, with text, images, and voice calls not counting against data; when plan data is used up, the connection remains active but is throttled; unused data and minutes can roll over to the following month; and most plans support unlimited calls to any operator and region in Brazil. The website claims to offer “the largest 5G coverage in Brazil,” but it does not provide quantitative details such as a coverage map, speeds, SLA, delivery rate, or call completion rate.
The website does not disclose specific plan prices, unit rates, or a tariff table in the main content. It only states that users can freely choose a plan, with no billing surprises and no contract lock-in. For recurring top-ups, users can receive billing information every month via WhatsApp. If using a credit card, the system charges automatically; if using Pix, the bill is sent via WhatsApp on the due date. This is convenient for local Brazilian users, but the lack of transparent pricing makes it difficult to assess its true value for money in comparisons.
Its strengths include strong localization, support for number portability with a bonus of up to 5GB, both eSIM and physical SIM options, and short-code instructions for processes such as activation, top-ups, and checking the phone number. Customer support channels include WhatsApp, Call Center, *288, 10543, and email. The drawbacks are also clear: no public plan pricing; no API, SDK, Webhook, or enterprise integration documentation; missing key performance information such as SMS delivery rate, voice call completion rate, and 5G speeds; and compliance is limited to mentioning Anatel qualifications, without further details on LGPD, privacy, or anti-abuse policies.
Mais Voz is suitable for individual users who live or work in Brazil, or who need a Brazilian mobile number, 5G internet access, WhatsApp communication, and number portability. If a business needs SMS verification codes, voice notifications, email delivery, or IM interfaces, the Mais Voz website does not demonstrate those capabilities, and alternatives such as Twilio, MessageBird, or local Brazilian operator solutions may be more appropriate. The main content does not provide information on access from mainland China, and payment methods are mainly credit card and Pix, which creates a relatively high barrier for non-Brazilian users.
