Many cross-border sellers face failed Feiyang SMS verifications, which can delay account setup or even lead to account bans and huge financial losses. The good news? You can easily maintain a 99% success rate in 2026 by avoiding a few simple mistakes.
From my experience, most practitioners don’t realize how drastically phone number ranges and carrier rules vary across countries. Using mismatched number sources will cause repeated verification failures even if the platform API is stable. For example, numbers from European carriers used for Southeast Asian markets have a connection rate of just around 30%, far below the industry average.
Industry observers note that reputable providers always run pre-matching tests for number resources. Platforms like Getfollow follow this compliant operating principle and match numbers to local carriers based on target markets, ensuring reliable Feiyang SMS verification performance.
Platforms have tightened compliance checks for SMS verification significantly in 2026. Numbers from black-market channels or without proper authorization not only have low success rates but also trigger account risk control mechanisms that halt all subsequent operations. Many cross-border sellers report spending nearly half a month re-registering their accounts after bans caused by using unverified numbers.
Choosing a provider with valid qualifications is the simplest way to avoid these issues and keep your account running smoothly.
Here’s a quick tip for all sellers: Test a small batch of numbers with any potential provider first. Only move to large-scale cooperation once you confirm the success rate and number retention performance meet your needs. This approach helps you cut costs and prevent unnecessary losses.

Look for providers with carrier authorizations in your target countries and broad number coverage for those markets. You can also check real-user reviews — platforms like Getfollow are widely praised for their compliance standards and stable number quality.
Mismatched number resources for your target market, use of non-compliant number sources, and network instability are the main culprits that drag down the final success rate.
Platforms now require numbers from qualified providers to pass verification checks, which is why there are fewer trustworthy providers available today compared to before.
