This article offers several tips for developers of Wireless Application Protocol (WAP) content with Wireless Markup Language (WML) WMLScript from Martin Frost, author of Learning WML and WMLScript from O'Reilly & Associates.

One basic error is failing to check the application on a variety of browsers, displays and devices. Incompatibility, especially among WAP browsers, remains a serious problem until an official test suite and certification program are more widely used. Other common pitfalls include deploying files too large for available bandwidth, using server-side scripts rather than WMLScript to check user entered values, using timers, relying on image alignments and failing to use and widely test character entities.
