The limited number of sites and unattractive charges are problems arose in the process of operators and icps deploying the service and the restrictions on the terminals mostly refer to the small - sized displays of the handsets and the inconvenience of entering characters through the keyboard, which are manufacturers problems. as to slow connectivity, it seems to be the weakness of wap. however, the fact is that there is a limit of 9600 bits on the circuit - switched data services provided by the gsm network and this is the very bearer mode that is currently selected by wap established on the network layer. this only means that people do not accept wap over csd
站點少、資費並不具吸引力等缺點是運營商與icp在對該業務推廣的過程中所顯現的問題；來自於終端的限制則是手機製造商的問題，雖然各大廠商都推出了支持wap的手機，但用戶的批評大都集中在手機屏幕太小及輸入不方便；至於連接速度慢，這似乎是wap本身的缺陷，但事實是gsm網路所能提供的基於電路交換的數據業務存在9600bits的限制，而建立在網路層之上的wap目前選擇的恰恰是這種承載方式，因此只能說wapovercsd這種業務提供模式人們不能接受。
