A useful solution starts with context.
A virtual number is not interchangeable across every country, provider or application. I help check the geography, supported voice or SMS capabilities, verification requirements and expected usage before a purchase decision. Routing may connect calls to an app, PBX or forwarding destination, with voicemail and billing controls where available. Number rental and per-minute charges are separate from configuration work. Kandrex provides context for business communications and number management, but this service does not guarantee a number can receive third-party OTPs. We test the agreed communications use case and leave account ownership and provider billing visible to you.
What I can help with
- Supported geography and capability review
- Provider KYC and number selection guidance
- App/PBX routing, forwarding and voicemail setup
- Usage and recurring billing explanation
Bring the problem, not a finished specification.
Share the current situation and your priorities. We’ll identify missing information together before agreeing to build.
- Your business use case and desired country
- Expected voice/SMS volume and destination
- Provider-required verification completed by you
You complete sensitive verification yourself. Never send passwords, PINs, tokens or OTPs in a message.
A clear sequence, with review built in.
- 01
Confirm the supported use case and jurisdiction.
- 02
Review availability, capabilities and recurring charges.
- 03
Guide legitimate provider verification.
- 04
Configure routing and test permitted functions.
- 05
Explain number management and billing controls.
What you receive
- Number selection and routing guidance
- Verified configuration for agreed capabilities
- Recurring-cost and usage notes
The final checklist is agreed in the scope. If an external decision or dependency prevents completion, the status and the next available step are made clear.
Pricing & running costs
Setup is quoted after provider review. Number rental, calling, SMS and subscription charges are separate and may vary by geography.
Before starting, we agree what is included, who pays third-party charges and what would require a revised quote. No fixed price or processing timeline is assumed.
Important limitations & privacy
Availability and KYC approval belong to providers. A number is not guaranteed for OTP verification; calling and messaging must comply with country and provider rules.
Only necessary information is requested for the agreed task. Sharing, access and document retention are discussed before handling sensitive material. Read the privacy notes.
Before you get in touch
Will it work for every OTP?
No. Third-party services and carriers may reject virtual numbers.
Can I choose any country?
Only supported geographies and number types are considered after verification checks.
Who owns the account?
You should control the provider account and understand renewal and usage charges.
