When sms-activate.org shut down on December 22, 2025, I had 3 production systems relying on their API. Here's what happened when I tested every alternative I could find.
The Test Methodology
I wasn't going to trust marketing pages. I spent $50 on each service and ran identical tests:
- 10 WhatsApp verifications (hardest — aggressive VoIP detection)
- 10 Telegram verifications (moderate difficulty)
- 10 Instagram verifications (inconsistent)
- 5 Google account verifications (very strict)
- 5 random service verifications (Discord, TikTok, etc.)
All tests used US, UK, and Indonesian numbers. I timed everything and noted the exact failure modes.
The Results
Success Rates (% of codes received)
| Service | Telegram | Overall | Avg. Delivery Time | |||
|---|---|---|---|---|---|---|
| VerifySMS | 78% | 90% | 55% | 40% | 66% | 34s |
| 5sim.net | 72% | 88% | 48% | 35% | 61% | 41s |
| sms-man | 65% | 82% | 42% | 30% | 55% | 52s |
| SMSPool | 80% | 85% | 60% | 45% | 68% | 28s |
| TextVerified | 92% | 95% | 88% | 80% | 89% | 15s |
| Receive-SMS (free) | 5% | 15% | 2% | 0% | 6% | N/A |
Takeaway: TextVerified crushed everyone — but it's US-only and costs $2-5 per number. For international coverage at a reasonable price, it's a different game.

Cost Per SUCCESSFUL Verification (the metric that matters)
This is what most reviews ignore. If a service costs $0.30 but only works 50% of the time, your effective cost is $0.60.
| Service | Sticker Price | Success Rate | Real Cost | Auto-Refund? |
|---|---|---|---|---|
| VerifySMS | $0.20-0.80 | 66% | $0.30-1.21 | ✅ Yes |
| 5sim | $0.15-0.60 | 61% | $0.25-0.98 | ❌ Manual |
| sms-man | $0.10-0.50 | 55% | $0.18-0.91 | ❌ Manual |
| SMSPool | $0.30-1.00 | 68% | $0.44-1.47 | ❌ Partial |
| TextVerified | $2.00-5.00 | 89% | $2.25-5.62 | ✅ Yes |
Critical note on refunds: Without automatic refunds, your "real cost" is the sticker price divided by success rate. With auto-refunds (VerifySMS, TextVerified), failed attempts cost you nothing — so the "real cost" is just the sticker price for successful ones.
Service-by-Service Breakdown
5sim.net — The Obvious First Choice
Everyone from sms-activate migrated here first. The interface is similar, the API is compatible.
What works: Huge country selection (180+), decent API, crypto payments.
What doesn't: The web interface feels like 2015. No mobile app. Refunds require opening a support ticket. Some numbers are recycled too aggressively — I got a number that was already linked to someone else's WhatsApp.
Verdict: Good for developers who need API compatibility. Not great for end users.
sms-man.com — Budget Option
Cheapest per-number pricing I found.
What works: Low prices, especially for social media services.
What doesn't: Slow. Average delivery was 52 seconds (vs. 15-34s for others). Interface is confusing — I accidentally bought 3 numbers for the wrong country because the UX is that bad. No mobile app.
Verdict: Use if budget is the only concern and you don't mind waiting.
SMSPool — The Privacy Option
Claims to use non-VoIP numbers, which means better success rates for services that block virtual numbers.
What works: Genuinely good success rates. Their non-VoIP numbers do work better for WhatsApp and Instagram.
What doesn't: Smaller inventory. Popular country/service combos are often out of stock. Pricing is opaque — different prices for different "quality tiers" that aren't well explained.
Verdict: Best raw success rates in the budget category. Stock issues are frustrating.
TextVerified — The Premium Option
Real US carrier numbers. By far the best success rates.
What works: Everything works. 89% overall success rate is unmatched. Fast delivery.
What doesn't: US numbers only. Expensive ($2-5 per number). Limited availability — popular services sell out fast.
Verdict: If you only need US numbers and budget isn't a concern, nothing beats this.
VerifySMS — Disclosure: I Built This
Full transparency: I'm the developer behind VerifySMS. That's why I ran these tests — I needed to know where we actually stand.
What works: Automatic refunds (this is genuinely the feature I'm most proud of), native iOS app, 150+ countries, 40 languages.
What doesn't: Success rates for Instagram and Google are mediocre. We're still building our provider network. No Android app yet. No developer API yet.
Verdict: I won't claim we're the best. We're competitive on price, strong on UX, and the automatic refund policy makes the effective cost lower than the numbers suggest. But if you need US-only with maximum success rates, TextVerified is better.
Free Services (receive-sms-online.info, etc.)
I tested 3 free services. 6% overall success rate. Numbers are shared publicly, meaning they're already burned on every major platform. Don't bother.
API Migration Guide
If you're migrating from sms-activate's API, here's a compatibility matrix:
| sms-activate Endpoint | 5sim Equivalent | sms-man Equivalent |
|---|---|---|
getNumber |
GET /v1/user/buy/activation/{country}/{operator}/{product} |
POST /get-number |
getStatus |
GET /v1/user/check/{id} |
POST /get-sms |
setStatus (cancel) |
GET /v1/user/cancel/{id} |
POST /set-status |
getBalance |
GET /v1/user/profile |
POST /get-balance |
My recommendation: Don't build provider-specific integrations. Build an abstraction layer:
interface SMSProvider {
getNumber(country: string, service: string): Promise<{id: string, number: string}>;
waitForCode(id: string, timeoutSeconds: number): Promise<string>;
cancel(id: string): Promise<void>;
getBalance(): Promise<number>;
}
Then implement this for each provider. When a provider goes down — and they will — you swap in the next one without touching application code.
Final Rankings
For developers needing API + international: 5sim > VerifySMS > sms-man
For end users wanting ease of use: VerifySMS > SMSPool > 5sim
For US-only, maximum reliability: TextVerified (no contest)
For budget: sms-man > 5sim > VerifySMS
Avoid: Free services, any service without a clear refund policy
These results are from January-March 2026. Success rates shift constantly as platforms update their detection. I'll update this post quarterly. Follow to stay updated.
Disclosure: I'm the developer behind VerifySMS. I've tried to be as honest as possible, including where competitors beat us. If you think my testing methodology is flawed, call me out in the comments.
