What It Is

Dexub positions itself as a QR Verification & SMS Platform. The core workflow is to upload an image in the dashboard, use the camera, or read a QR code from the clipboard; after decoding the link, you copy the SMS link on the page back into the system, which then parses the phone number and message content and sends the SMS. It is not a traditional SMS marketing platform, but more of a tool for QR-triggered verification workflows.

Core Capabilities

In terms of channels, the extracted text clearly supports only SMS; there is no mention of email, voice, or IM. For regional coverage, Dexub claims it can send international SMS to most countries worldwide via API providers, but it does not provide a country list, routing types, or localized sender information. For APIs and integrations, Dexub offers a reliable sending API and also allows administrators to connect their own GSM modem through local bridge software, which gives some flexibility to users with local SIM resources or special routing needs. Security features include Google OAuth, encrypted sessions, real-time logs, and complete sending history.

Pricing and Performance

Pricing is very simple: registration is free, there is no subscription, and 1 SMS credit costs $4, corresponding to 1 verification SMS. Credits do not expire. The terms state that charges apply only when a message is successfully sent, and credits are not deducted for failures caused by technical errors. However, credits are generally non-refundable, with only a few cases such as duplicate charges or account theft handled on a case-by-case basis. On the performance side, the service only describes itself with terms such as reliable API and real-time logs, while also explicitly stating that uninterrupted service is not guaranteed. SMS delivery depends on third-party carriers and APIs, and there is no data on delivery rates, latency, SLA, or throughput.

Pros, Cons, and Who It’s For

The advantages are a clear onboarding path, no subscription requirement, manageable costs for low-frequency use, and support for a self-owned GSM modem bridge. The downsides are that $4 per message is extremely expensive for regular verification codes or notification SMS, making it unsuitable for bulk use; coverage, delivery quality, and compliance details are also insufficiently disclosed. Dexub is better suited to individuals or small teams with low-frequency or temporary needs who need to extract and send verification SMS from QR-code-based workflows.

Access from China

The available text does not provide information on network connectivity from mainland China, Chinese-language support, or RMB payments; the only payment-related item mentioned is Stripe payment details. If the service is intended for China-facing business, it is advisable to first evaluate local alternatives such as Alibaba Cloud SMS and Tencent Cloud SMS. If an international SMS API is needed, it can be compared with Twilio, Vonage, MessageBird, and Telnyx.
