Testing a South Sudan sign-up flow without a +211 SIM

The problem: a South Sudan launch and no local SIM on the team

Picture a product that already serves East Africa and is adding South Sudan to its country picker. QA needs to confirm that a +211 number passes validation, receives the code and lands the user on the right screen. Nobody on the team is in Juba, international roaming is slow to arrange, and borrowing a colleague's personal phone for test accounts is a habit worth breaking.

A remote South Sudan verification number solves the narrow part of that problem: getting one real code onto a +211 line, on request, from a script or a browser. Our QA testing page covers the wider workflow.

What does OTP Route offer for +211 numbers?

The OTP Gateway assigns a South Sudan number for a single verification. Pick the service and the country, use the number in the app, and the code is delivered to the dashboard and to your systems. The activation stays open for 20 minutes, and you pay only if the SMS arrives.

The current snapshot shows more than 900 services for South Sudan, including WhatsApp, Facebook, imo, Telegram, Instagram, TikTok, Snapchat, Viber, Signal, Google (Gmail & YouTube), X (Twitter) and Uber. Inventory shifts during the day, so treat that as a guide and query the live list before a run.

How does the South Sudan OTP API work in code?

Point your client at https://otproute.com/api/v1 with a Bearer key (or_live_…) from the Developer console. The country id is ss.

• GET /api/v1/prices?country=ss&service=<id> returns today's price for the pair.
• POST /api/v1/activations with {"service": "imo", "country": "ss"} reserves the number.
• GET /api/v1/activations/{id} lets you poll for the code; POST /api/v1/activations/{id}/cancel releases it early.

For parallel suites, a webhook beats polling. Subscribe to activation.sms_received and activation.expired, verify X-OTPRoute-Signature (HMAC-SHA256 of <t>.<raw body> with the endpoint secret), throw away stale timestamps, and make the handler idempotent on the activation id. Pipelines in particular benefit, as described in SMS OTP testing in CI pipelines. Each account may hold 10 keys and 5 webhook endpoints, with throughput capped at 300 requests per minute.

No developer handy? Use the dashboard

1. Sign in and open the OTP Gateway.
2. Choose South Sudan, then the service you are testing.
3. Check the price shown, confirm, and copy the +211 number.
4. Enter it in your app and wait on the same page for the code.
5. Cancel if the test is called off; the amount goes back to the wallet.

Number format, language and local context

South Sudan received its own country code, +211, after independence in 2011, so older contact data and some legacy validation libraries can still behave oddly. Mobile numbers are nine digits after the country code. When written for local dialling they usually carry a leading 0; drop it when converting to E.164 and store +211 plus the nine digits.

English is the official language, and Juba Arabic is widely spoken, so verification texts may arrive in English or Arabic depending on the app's locale. Testing both templates, plus the right-to-left rendering of any Arabic copy, is a sensible addition. Teams also test here for humanitarian and logistics operations, regional business accounts, and diaspora users who keep a +211 number abroad.

What if the code doesn't arrive?

• Let the 20-minute window run before retrying.
• Check whether the service accepts virtual numbers; some decline them.
• Try again later, or switch to a different service route, rather than placing orders in a rapid loop.
• Confirm your webhook endpoint is not rejecting valid signatures.

An expired or cancelled activation refunds itself; there is nothing to claim. Further ideas are in reducing failed OTP deliveries.

Long-term lines, wallet and sandbox

South Sudan has no self-serve long-term number on OTP Route. Dedicated Numbers, from $1.95/month, are available only in the United States and Canada. If you need a lasting +211 line, write to [email protected]; whether it can be arranged depends on local rules.

Payment is a prepaid USD wallet with no monthly fee: top up by card or USDT/USDC, receive a PDF invoice for each top-up, and see live rates on the pricing page. For development, a sandbox mode can be enabled on request to return simulated numbers and codes, so the integration can be proven before real spend.

Frequently asked questions

Can I receive a South Sudan SMS OTP without being in the country?

Yes. The OTP Gateway gives you a +211 number remotely, and the code appears in the dashboard and through the API.

What is the API country id for South Sudan?

Use ss when creating activations or asking for prices.

Should I store +211 numbers with the leading zero?

No. Strip the local 0 and store the E.164 form, +211 followed by nine digits.

How many services work with South Sudan numbers?

The live list currently holds more than 900 services, though availability changes through the day.

Can I test my app's South Sudan sign-up flow from a CI pipeline?

Yes. Create the activation with country ss from your job, receive activation.sms_received on a signed webhook, and submit the code in the same test step. A sandbox account lets you rehearse this without spending wallet funds.

What happens if I cancel an activation?

The full amount returns to your wallet automatically, the same as when the 20-minute window expires without a code.

Is a +211 number for testing allowed for any use?

No. Use it to test or operate your own legitimate products, follow each service's terms, and keep to the OTP Route Acceptable Use Policy.
