Hi Experts,

a remote user that using Ipad want to access B1 8.8 SP00 PL20 from remote site. Sap b1 integration components and mobile application for Ipad are installed. How to do that ?

We have used mifi umts wireless router huawei E585. if the Ipad do not have simcard but only wifi, I think it is impossible, what about iphone, could Iphone access B1 from remote site if the iphone have simcard ? Pls advice. TIA
