Many “SMS verification” products are simulated or recycled routes. For production B2B workflows, a real SIM inbox on the same platform as your farm hardware reduces integration risk.
Virtual / simulated SMS
- Cloud phones often cannot receive carrier SMS to a real inbox
- Some API routes return codes without a durable number lifecycle
- Country mismatch triggers platform fraud checks
Real SIM OTP
- Codes arrive on actual carrier routes — needed for sign-up, 2FA, and app-store flows
- Wallet billing per successful receive is common in B2B
- Match country/region to the app or ad market you test

市面不少「接码」为仿真或不稳定通道。生产级 B2B 流程需要真实 SIM 收件箱，与农场硬件同站可显著降低对接风险。
虚拟/仿真短信
- 云手机常无法真实收运营商短信
- 部分 API 只返回码、无稳定号码生命周期
- 国家不匹配易触发平台风控
真实 SIM OTP
- 验证码走真实运营商通道 — 注册、2FA、应用商店流程常用
- B2B 常见按成功收信钱包计费
- 号码国家/地区需与业务市场一致
