GoIPPro Verify uses real SIM cards in 30+ countries to test whether your SMS actually arrive. Detect fake delivery reports, content manipulation, and sender ID changes — before your customers do.
You pay an SMS aggregator to deliver 1 million messages a month. They report "97% delivered." Looks great on paper. Here's what actually happens:
Your provider reports "delivered" — but the message never reached a real phone. The DLR was generated by an intermediate hub, not by the destination network. You're paying for air.
Your OTP says "Your code is 4821." What the customer receives: "Your code is 4821. Download our app: [spam link]." Grey routes inject ads into your messages.
You send from "YourBrand." The customer sees a random number or a different sender name. Your brand looks like spam. Trust evaporates.
Messages to certain operators or countries simply vanish. No error, no DLR failure — just silence. Your customers can't log in, can't verify, can't transact.
You can't fix what you can't see. That's where GoIPPro Verify comes in.
Four steps. Real data. No guesswork.
Through your provider's normal route — same API, same flow. The destination is one of our test numbers.
On a real SIM card, on a real device, on a real local network. Not a virtual number. Not a SIM farm.
Delivery status, content integrity, sender ID, latency, SMSC identification, MNP support — all in one report.
Keep the provider. Switch the route. Negotiate a discount. Or just sleep better knowing the truth.
The SMS testing market has established players — TelQ, Testelium, TestMySMS. Here's why GoIPPro Verify is a fundamentally different proposition.
Other platforms maintain dedicated test number pools. Smart providers learn to recognize and whitelist them. Our SIMs are part of a live B2B traffic network — they receive real calls and SMS every day. There is nothing to whitelist because there is nothing unusual about them.
Most testing platforms excel in Western Europe and the US. Try testing delivery to MTN Nigeria, Irancell Iran, or Jazz Pakistan. GoIPPro has local SIMs actively working in these exact markets. We don't stretch to cover them — we live there.
Our SIMs carry real daily traffic and rotate naturally. We don't need to "refresh" test numbers artificially. The SIM that tests your delivery today received 15 real calls yesterday. No provider can whitelist what they can't distinguish from regular traffic.
Testing platforms build SIM networks specifically for testing — expensive. Our SIM network already exists and is funded by our core traffic business. Verification is an incremental service on top of existing infrastructure. Better prices, same quality.
| Feature | What It Checks |
|---|---|
| Delivery Verification | Did the SMS actually arrive on the handset? Compare real delivery with your provider's DLR. |
| Fake DLR Detection | Identify when your provider reports "delivered" but the message never arrived. |
| Content Integrity | Was the message text modified, truncated, or had content injected? Character-by-character comparison. |
| Sender ID Check | Does the recipient see your brand name or a random number? |
| Delivery Latency | Real time from send to handset receipt — not SMSC timestamp. |
| SMSC Identification | Which SMS center handled the message? Reveals grey routes vs. direct connections. |
| MNP Testing | Does your provider correctly route to ported numbers? |
| Encoding Check | Was the character encoding preserved? Critical for Arabic, Chinese, Cyrillic. |
| Long SMS Handling | Was a multipart message delivered correctly or split/lost? |
| Scheduled Testing | Automated tests at set intervals — 24/7 monitoring without manual effort. |
Millions of OTPs and promotional SMS monthly. If even 5% are silently undelivered — thousands of users can't verify, can't deposit, can't play. Every undelivered OTP = lost revenue.
OTP delivery is a security requirement, not a nice-to-have. If your SMS provider silently fails, you have a compliance gap. Get proof of delivery — or proof of failure.
Order confirmations, shipping updates, return codes. When they don't arrive, support tickets spike and NPS drops. Know which routes work before customers find out they don't.
You resell SMS routes. Your reputation depends on delivery quality. Audit your upstream suppliers, catch grey routes, and prove quality to your own clients.
Campaign ROI depends on delivery. If 30% of your SMS never arrive, your campaign analytics are fiction. Verify real delivery and optimize your provider mix.
If your users can't receive verification codes, they can't log in. Period. Test your 2FA delivery across every operator and country you serve.
REST API, Dashboard, SMPP — pick what works for you. Typical API integration takes 1–2 hours.
// Send a test SMS POST /api/v1/test { "destination": "+90532XXXXXXX", "sender_id": "YourBrand", "content": "Your verification code: {{test_id}}" } // Webhook response { "delivered": true, "latency_ms": 4200, "sender_id_received": "YourBrand", "content_received": "Your verification code: A7X9K2", "content_match": true, "smsc": "Turkcell SMSC", "timestamp": "2026-03-24T14:22:07Z" }

TelQ uses dedicated test number pools. We use live SIM cards that are part of our active traffic network — they receive real calls and SMS daily. This makes whitelisting practically impossible. We also have stronger coverage in emerging markets (Turkey, Nigeria, Pakistan, Iran, Egypt) where most testing platforms are thin.
Our SIMs carry real daily traffic — voice calls and SMS from our B2B network. They are indistinguishable from regular subscribers. We also rotate SIMs naturally as part of our normal operations. There's nothing to whitelist because there is nothing unusual about them.
Yes. GoIPPro Verify can test voice delivery, CLI pass-through, and call quality (ASR/ACD) using the same SIM network. Contact us for voice testing details.
30+ countries with active local SIMs across all major regions — Asia, Africa, Middle East, Europe, Latin America. Full coverage list available on request.
REST API integration typically takes 1–2 hours for a developer familiar with webhooks. Dashboard access is instant — no integration needed.
