From my experience, most cross-border sellers targeting the Japanese market face delays in code delivery or complete failure to receive verification messages, which often leads to account suspension by platforms. Industry observers note that these unofficial services rely on bulk spoofed numbers, resulting in poor reliability: their message retention rates only range from 50% to 70%, far below the performance of legitimate SMS channels.
Many cross-border professionals agree that choosing a reputable SMS service provider is the key to avoiding the pitfalls of unreliable code delivery. Platforms like Getfollow stand out in the industry for their compliant operation model — they never use grey-market channels, effectively minimizing the risk of account bans.
Here’s a practical tip: ask the provider for delivery rate reports covering the past three months before signing up, and run a small-scale test order first to confirm everything works as expected. For cross-border businesses, stable SMS delivery is the foundation of conversions and customer retention, so don’t risk account suspension just to save a little on costs.
| Service Type | Typical Retention Rate | Compliance Status |
|---|---|---|
| Unofficial Japanese SMS receiving services | 50%–70% | Non-compliant |
| Reputable legitimate SMS providers | 90%+ | Fully compliant |
Most delays stem from the use of low-quality, spoofed numbers by unofficial service providers, which are often blocked by Japanese carriers and platforms.
Request recent delivery rate reports and run a small test order to check if messages reach recipients reliably without being marked as spam.
