TL;DR



GrizzlySMS (grizzlysms.com) is an active sms-activate compatible SMS verification service running roughly 2,401 services. It uses real physical SIMs (not VoIP) so delivery on WhatsApp, Telegram, and Google is solid, but coverage is narrow compared to full-catalog competitors. VirtualSMS offers the same sms-activate compatible API (so existing GrizzlySMS code works with a base-URL change) plus 145+ countries via our global activation network (GrizzlySMS focuses on a smaller country set), plus dedicated real-SIM rentals (1-30 day periods), a use case GrizzlySMS does not support. WebSocket live delivery is available today; reseller webhooks land in the next API release. Alternatives also include DaisySMS (shut down on March 26, 2026), SMS-Activate (shut down Dec 2025), 5sim, SMS-Man, SMSPVA.



If you searched for grizzlysms, grizzly sms, grizzly-sms, grizly sms, or GrizzlySMS, you're in the right place.













## Virtual SMS is an account verification platform, not just an SMS API




One account, four products:





- SMS verification : one-time codes for 2,500+ services on real carrier SIM cards, from
 $0.05

 , pay only when the code arrives.
- Dedicated number rentals : keep a real SIM number for
 1-30 days

 for 2FA, account recovery, or business use.
- Proxies : residential & mobile proxies to pair with your verifications (match IP geography to number geography).
- Cloud Browser sessions (Beta) : run verification and multi-account flows in a hosted browser.
- MCP server + REST API + webhooks : wire numbers and codes into AI-agent and automation pipelines.





Every service compared on this page sells SMS codes and stops there.







## What happened to GrizzlySMS ?




- 2021


### GrizzlySMS launches as budget sms-activate clone

 grizzlysms.com launches as a Russian-origin sms-activate compatible marketplace targeting the budget segment with a smaller service catalog than sms-activate or 5sim.
- June 2023


### r/GrizzlySMS subreddit opened

 GrizzlySMS creates r/GrizzlySMS as an owned-media channel for content marketing. Growth is modest (~22 subs/month) and posting cadence is sparse (every few weeks), signaling execution-light marketing operations.
- 2024-2025


### Duplicate content + AI-slop tone surface

 The same Reddit post ("How to Use WhatsApp Without a Phone Number") was published four times identically without editorial review. Content style trends toward AI-assistant patterns (emoji-heavy openers, "Look no further!"-style CTAs), signals of automated content with minimal human QA.
- December 2025


### SMS-Activate shuts down, Grizzly absorbs displaced users

 With SMS-Activate offline, sms-activate-API-compatible services (GrizzlySMS, DaisySMS, SMS-Man, VirtualSMS, SMSPVA) absorb migrating users. GrizzlySMS sees traffic bump but is constrained by narrower country coverage.
- 2026


### Quality + coverage differentiation matters more

 As the remaining sms-activate compatible services compete for migrated users, the differentiators become real-SIM quality (most now use real SIMs), country coverage (services like VirtualSMS with broader global coverage win here), and advanced API features (WebSocket live delivery today; webhooks on the next API release), GrizzlySMS has basic API parity without these extensions.







## Why switch from GrizzlySMS ?



Common pain points users report, and how VirtualSMS addresses them.









### Limited Global Reach



GrizzlySMS has a smaller inventory than what DaisySMS users need. VirtualSMS offers 145+ countries through our global partner network.










### No Dedicated SIM Rentals



GrizzlySMS doesn't offer dedicated real-SIM rentals. VirtualSMS provides dedicated real carrier-issued SIM numbers for long-term rentals (1-30 days).










### Limited Coverage



GrizzlySMS has limited country coverage and stock. VirtualSMS offers 145+ countries with massive inventory via global providers, plus dedicated real-SIM rentals.










### Basic API Features



GrizzlySMS has basic sms-activate compatibility but lacks WebSocket live updates today; area-code filters and carrier selection land on VirtualSMS in the next API release.











## One URL change. That's it.



GrizzlySMS uses the sms-activate compatible API format, and so do we. Change the base URL and
 you're done.










 GrizzlySMS (old)




// GrizzlySMS (sms-activate compatible)
const BASE_URL = "https://grizzlysms.com/stubs/handler_api.php";








 VirtualSMS (new)


 // VirtualSMS, more countries, dedicated real-SIM rentals, same API
const BASE_URL = "https://virtualsms.io/stubs/handler_api.php";

## GrizzlySMS Alternative: Frequently Asked Questions



Everything users asked us while migrating from GrizzlySMS.






 Is GrizzlySMS legit?




 It's an operating sms-activate-compatible service, but Trustpilot skews low (~2/5) over pre-used numbers and refund refusals; it's strongest for Amazon/Telegram/Discord, weaker on WhatsApp/Instagram.





 Does GrizzlySMS resell or own its numbers?




 Users report recycled/pre-used numbers arriving "already verified." VirtualSMS uses real carrier SIMs that aren't shared-pool, with an auto-refund if a code doesn't arrive.





 What is the best GrizzlySMS alternative?




 VirtualSMS: same API (one URL change), broader coverage, real non-recycled SIMs, plus rentals + proxies + Beta cloud browser.





 What do people on Reddit recommend instead of GrizzlySMS?




 Real-SIM services with broader coverage and auto-refund; VirtualSMS fits that profile.





 Is grizzly sms down?




 As of 2026, GrizzlySMS (grizzlysms.com) is operational. The domain is Cloudflare-protected and serves the production marketplace. If you are getting errors, check your VPN or Cloudflare challenge, GrizzlySMS aggressive bot detection sometimes blocks legitimate users temporarily. If the issue persists across networks, check r/GrizzlySMS or their Telegram support channel for service status.





 Does GrizzlySMS have an API?




 Yes, GrizzlySMS implements the sms-activate compatible API standard (/stubs/handler_api.php endpoint, getNumber/getStatus/setStatus action names, standard response format). This means code written against sms-activate, DaisySMS, VirtualSMS, SMS-Man, or SMSPVA can use GrizzlySMS with only a base-URL change. GrizzlySMS does NOT offer WebSocket live delivery; VirtualSMS adds WebSocket today, with webhook callbacks and area-code filters on the next API release.





 Will my GrizzlySMS code work on VirtualSMS?




 Yes, change one line. Both services implement the sms-activate compatible API: same /stubs/handler_api.php endpoint, same core action names (getBalance, getNumber, getStatus, setStatus), same response format, same api_key parameter. Replace https://grizzlysms.com/stubs/handler_api.php with https://virtualsms.io/stubs/handler_api.php and your code runs unchanged. You also get access to WebSocket live delivery today (if you want to upgrade from HTTP polling); reseller webhook callbacks land in the next API release.





 How is VirtualSMS different from GrizzlySMS?




 Four differences. (1) Country coverage: VirtualSMS has 145+ countries via our global activation network; GrizzlySMS has a smaller catalog focused on core markets. (2) Dedicated rentals: VirtualSMS provides dedicated real carrier-issued SIM rentals for 1-30 day periods, GrizzlySMS doesn't offer long-term rentals. (3) WebSocket live delivery today: instant SMS via WebSocket instead of 3-second HTTP polling. (4) Reseller webhook callbacks land in the next API release, GrizzlySMS lacks them entirely.





 Is grizzlysms cheaper than VirtualSMS?




 Per-activation pricing is comparable, both target the budget-to-mid segment of the sms-activate compatible market. GrizzlySMS sometimes runs temporary promotions on specific services. VirtualSMS's value comes from broader country coverage (145+ vs narrower), real-time delivery (WebSocket), and long-term rental options (dedicated real-SIM numbers for 1-30 day periods), use cases where GrizzlySMS either charges more or doesn't offer the service at all.





 GrizzlySMS reviews: what do users say?




 Mixed. Reddit threads (r/GrizzlySMS, r/smsverification) report solid WhatsApp/Telegram delivery but limited service catalog and occasional stock-out issues for less popular services. Reported quality patterns match the budget-tier positioning: good for high-volume common services (WhatsApp, Telegram, Google), less reliable for long-tail services or specific countries. Support responsiveness varies, GrizzlySMS's Telegram support is faster than their ticketing queue.





 Does VirtualSMS or GrizzlySMS have a Telegram bot?




 VirtualSMS: yes, @VirtualSMSioBot. Full marketplace in Telegram (buy numbers, receive SMS, top up balance, check activations). GrizzlySMS: uses Telegram primarily for support/community (r/GrizzlySMS Reddit farm is their main owned-media channel); their main marketplace is web-only. For users who prefer a mobile-first Telegram flow: VirtualSMS bot is the faster option.
