Not Receiving WhatsApp SMS Code? 2025 Solution — GrizzlySMS
WhatsApp remains the world's most popular messenger, and any issues with number verification can completely block communication. In 2025, 14% of new users face delays in receiving SMS codes during registration or account transfer. Below, we'll examine the reasons, perform a quick diagnosis, and show how a GrizzlySMS virtual number can solve the problem in under 5 minutes.
Why WhatsApp Stays Silent
-
SMS gateway overload (especially during peak evening hours).
-
WhatsApp's security timer after three incorrect code entries.
-
Local carrier blocking international SMS.
-
Using VPN or proxy (IP address doesn't match the number's country).
-
Outdated app version.
These reasons cover 90% of cases. The timer and SMS blocking can only be resolved by changing your number.
Quick Checklist

Disable VPN and Wi-Fi, switch to mobile data.
-
Update WhatsApp to the latest version.
